CNN 10 | CNN Student News | February 8, 2018 | Earthquake in Taiwan

An earthquake in Taiwan, an unusually cold Olympics and the drone invention that could save lives are all ahead today  on CNN 10 I’m Carl Azuz at the CNN Center

We’re starting at an island that borders the East China Sea, where a magnitude 64 earthquake struck late on Tuesday One city in Taiwan that  was hit really hard was Hualien It’s on the northeast coast of the island, and it’s where at least eight people were killed and 262 others  were injured  Many people are spending the night outside for fear their homes aren’t safe to sleep in

Dozens of aftershocks have hit the area and an estimated  35,000 people have no running water This isn’t the deadliest earthquake to hit Taiwan Forty people were killed in 2016 when a magnitude 64 quake  struck the island and 2,400 people died in 1999 after a magnitude 73 tremor

Taiwan is on the Pacific Ring of Fire, a horseshoe shaped area that runs around the edge of the Pacific Ocean Earthquakes and volcanoes are common  from Chile to Indonesia Still, residents say their nerves are frayed Dangerously tilting buildings have become symbols of how destructive  earthquake can be Taiwan’s government says hundreds of military troops and firefighters are helping with the rescue effort

(BEGIN VIDEOTAPE) KRISTIE LU STOUT, CNN INTERNATIONAL CORRESPONDENT: Dramatic scenes and devastation from Taiwan after a major earthquake overnight Now, the 64  magnitude quake struck late on Tuesday night, just off the east coast of Taiwan, near Hualien county Rescue crews are racing to save lives In  fact, 236 people have been rescued so far

  The president of Taiwan, Tsai Ing-wen, took to Twitter earlier to thank first responder, saying this, quote: Thank you to our first responders for  their tireless efforts in Hualien Rescue operations have been continuing night and day Right now, 145 people remain unaccounted for We will not  rest until all are found Now, again, that tweet was sent a few hours ago

The number of accounted for now stands at 85 Now, at least four buildings in the quake zone are  tilting or already collapsed and we are keeping a close eye on the Marshal Hotel, the Beauty Inn and Yun Men Tsui Ti building all in downtown Hualien  This is where rescue workers are scrambling to find any additional survivors To save lives, rescue workers are racing against time They’re  also racing against the danger of more aftershocks

In fact, a 54 magnitude aftershock hit near Hualien shortly after the larger quake Kristie Lu Stout, CNN, Hong Kong (END VIDEOTAPE) AZUZ: Moving north from Taiwan to where the 2018 Olympic Winter Games are just a day away It’s cold

Pyeongchang, South Korea, is surrounded by  mountains The forecast for the day of the opening ceremonies predicts high temperatures will be around 42 degrees Fahrenheit, but a plunge to the  20s during the day and the teens at night follows, before things warm up a little next week This could be one of the coldest Winter Olympics in history The "Reuters" news agency says in training runs, extremely cold snow has warped some  athletes’ skis, forcing coaches to throw them away You’d think that this means there’d be plenty of natural snow on the ground, but February is a  very dry month at Pyeongchang

(BEGIN VIDEOTAPE) PAULA HANCOCKS, CNN INTERNATIONAL CORRESPONDENT: Snowmaking started earlier in South Korea this season October saw the first artificial snow  hit the ski slopes and it hasn’t stopped since Pyeongchang certainly doesn’t have the same problem that Sochi in Russia had four years ago Any natural snow that falls here is going to say on  the ground It is cold enough

But the issue is, there’s just simply not that much natural snow After all, winter in Korea is the dry season Ian Honey is the project manager for SMI Snowmakers His company has already made snow for five Winter Olympics He started preparing for  Pyeongchang three years ago

  IAN HONEY, SMI SNOWMAKERS: Here, it’s all 100 percent manmade snow And as I said, we’ve had great temperatures We’ve been very lucky HANCOCKS: So, none of this is natural snow then  HONEY: Yes, 98 percent of the — manmade

  HANCOCKS: This has been the scene for months in Pyeongchang, mountainsides, rock and mist of manmade snow So, how do you actually make  it? HONEY: We’re doing very similar to what Mother Nature does We’re taking water and we’re forcing it into the atmosphere and we’re getting — we’re  generating a crystallize structure But the structure that we’ll generate is a more consistent structure Basically, they’re all the same, where  natural snow is very flake is different

HANCOCKS: Tourists don’t seem to mind the snow is manmade, enjoying the last peaceful day on the slopes before the games begin As for which is  better, natural or artificial, these two ski instructors say there’s no contest UNIDENTIFIED FEMALE: Artificial snow is good for skiing more than because we can more — speeding They’re really good HANCOCKS: And speed is what Olympic athletes want

We’ll no doubt hear soon enough whether they approve of Pyeongchang’s snow  There have been some heavy snowfalls in recent months A few weeks ago, there was a rush to preserve the snow after it fell, carving it into  massive blocks We now see why as the snow festival opens, massive sculptures towering over children who are more interested in the snow than  the art So, while it may not always look like the Winter Wonderland you’d expect from the Winter Olympics, the organizers say they’re ready

Let the games  begin Paula Hancocks, CNN, Pyeongchang, South Korea (END VIDEOTAPE) (BEGIN VIDEO CLIP) AZUZ (voice-over): Ten-second trivia Which of these scientists is famous for inventing a telegraph system? Thomas Edison, Alexander Graham Bell, Samuel Morse, or Johannes Gutenberg? Samuel Morse, the namesake of Morse code, invented an electric telegraph system in the early 1830s (END VIDEOTAPE) AZUZ: It’s hard to pinpoint exactly when the first drones were invented and put to use

Some say that unmanned balloons that were filled with  bombs and put in combat in the mid-1800s were the first types of drones But they weren’t really remotely operated They depended on the wind to  get them to their intended target and that didn’t always happen  Of course, in this century, uses for drones go far beyond war, to include surveillance, exploration, photography, racing And one young inventor is  hoping that smart drones will be able to navigate dangerous places, avoiding obstacles while searching for survivors

(BEGIN VIDEOTAPE) MIHIR GARIMELLA, INVENTOR: I’m Mihir Garimella I’m 18 years old and I’m a student at Stanford University in California I’m building autonomous  drones that can navigate and carry out critical missions in indoors spaces and I hope one day these drones can help save lives I’ve always been curious about how things work and then sort of using that curiosity to actually build things to solve problems When I was 14, I won  the Google Science Fair for building a fruit flies fire drone that can help first responders carry out certain rescues

  It all started with bananas Four years ago, my family went to India on vacation and when we got back, we realize that we left some bananas on the  kitchen counter and by that point, they’re rotting so our house is filled with fruit flies I kept trying to swat them, kept hitting really mad when  they kept escaping, but I also came curious how these tiny organisms, tiny brain, really bad eyesight, how could they possibly escape so effectively? So, fruit flies can’t see in very much detail, but that means that they can process what they can’t see and respond to that really quickly Fruit  flies actually have the fastest visual system on the planet They can see ten times faster than humans can

On the same time drones were just starting to become popular, I also realize that they could have tremendous potential to actually save lives  So, the problem is that they aren’t really good at reacting to their environments And so, I wanted to see whether we could draw this instinct  from the fruit fly that enables them to escape so effectively, to make drones good at responding to their environments And this is something  called bio mimicry, so looking to biology for models on how to design these solutions to really complex engineering problems Birds actually see using the images from each eye separately, and so, that’s similar to how we want to do this with a single camera

Fruit fly  see in terms of edges And so, I designed an algorithm that could sort of use both of those cues to process a stream from a single camera and make a  map of a 3D environment that it could then use to avoid obstacles So, what I’m trying to build now is this intelligence drone platform that can be used for a search and rescue construction, industrial inspection,  you know, inspecting power plants, all these applications, to sort of carry out these really critical lifesaving missions So, the idea is that you  take this drone, plug in different sensors based on whatever tasks you’re trying to accomplish And the drone would use the sensors to carry out  certain missions

  They can tell first responders the locations of trapped victims after an earthquake They can detect rusts in bridges or other infrastructures to  prevent collapse They could go on to nuclear power plant, pinpoint hot spots of radiation and say, you know, these things are going to leak or  these things are leaking because of these reasons  My dream is build something that can improve the lives of a billion people Success for me is these drones, you know, are really saving lives

(END VIDEOTAPE) AZUZ: Getting back to winter sports Not everyone can safely step in skis and sail down snowy slopes at more than 60 miles per hour But dozens of  folks recently did take a seat on a shovel and hurdle down hill at about the same speed at the World Championship Shovel Race It’s an annual event  at the Angel Fire Resort in New Mexico It costs between $20 and $70 to enter, depending on your age and skill level

And whether or not they  finish seated upright, every competitor there got to shovel snow  Hey, at least they had a handle on the challenge They were on the cutting edge of racing They competed at blinding speeds  This is CNN 10 where you know we’ve got the scoop on shovel puns

What will happen during an earthquake?

This simulation shows a magnitude 70 earthquake on the Hayward fault, and the area shown in this animation covers most of the populated San Francisco Bay Area

This is the highest-resolution earthquake simulation ever done for northern California that takes into account 3-dimensional geological structure and topography To achieve this level of detail, the simulation was done on one of the Lab's supercomputers, where the calculation ran on over 86,000 process for 18 hours Let's take a look at what happens The earthquake starts at the northern end of the fault A 50-km section of the fault ruptures, shown as the black line

The intensity of ground-shaking is shown according to the color scale on the right, where red indicates the strongest shaking of up to 1 meter per second–shaking that can damage buildings The blue color indicates shaking that could be felt, but not cause damage The earthquake only takes about 20 seconds to rupture, but the seismic waves traveling away from the fault shake the entire Bay Area for over 90 seconds The intensity of ground shaking varies from area to area, according to the pattern of slip on the fault itself and the geologic structure of the ground For example, low seismic wavespeeds of softer sedimentary rocks amplify shaking compared to harder rocks

That means that sedimentary basins like the San Pablo Bay, San Leandro Basin, Santa Clara Valley, Dublin-Pleasanton-Livermore Valley, and the Delta experience longer durations of shaking because their geologic structure can trap seismic waves Simulating ground motions during and after an earthquake, like in this animation, can help us evaluate seismic hazards and calculate potential damage to buildings The particular scenario represented in this simulation is just one possible rupture of the Hayward fault Future simulations will explore other possibilities, and will continue to help us prepare for earthquakes and their consequences

Observable: An Earthquake Globe in Ten Minutes

hello everybody welcome to Observable I'm Jeremy and today we're going to be visualizing some live earthquake data from the USGS in ten minutes or less so here we go so this is observable and the first thing we're gonna do is create a new blank notebook and this notebooks gonna be about earthquakes so we'll give it that title and then make a new cell and the first place to start when we're going to fetch our earthquake data is the URL of the USGS server that provides a GeoJSON file that has information for every quake that's happened around the world in the last week so we fill in that URL and as you can see that's just a JavaScript a piece of code with a string as the value and we're going to use the fetch web API to fetch the contents of that URL now that gets you a response but we're gonna it gives you a promise for the value we're gonna wait for that promise to resolve and get the JSON out of out of that URL so here we've got a feature collection of GeoJSON with a whole bunch of quakes in it you can see there's Alaska a magnitude 17 let's pull out an example earthquake here so that we can take a look at some of the properties so that's let's say the xxx earthquake in that list and we'll look at its properties and we'll see that it's a 4

6 off Papua New Guinea so we've got all the information we need to plot these earthquakes the next thing we need is a map of the world so mike has published some natural earth world maps in a few different resolutions we're going to go fetch one off of NPM through the unpkg service so we're going to get world add lists at a 110 meter resolution and that's a topo JSON file we'll get the wait for the Jason and get that back out and this gives us countries and raw land as you can see in the inspector there so what we're going to do is change the definition here and instead of just getting the value we're gonna use TopoJSON to pull out just the country's feature of that of that world geography so we'll do a topojsonfeature we'll take the world and we'll extract the countries now this isn't going to work because we've never loaded TopoJSON yet TopoJSON isn't defined so to fix that let's load in TopoJSON from NPM will require it this is a similar kind of thing that returns a promise and once it comes back the world will reevaluate and now we have our array of countries in the world with their geographies we'll also going to need d3 to do this this little map so we'll load in d3 as well and then the next step is to create the canvas that we want to draw the world into so let's set a size we'll start with 500 pixels tall and we'll call it our globe we'll get a canvas element from the standard library so I'm going to get a context for that canvas element which is going to be sized at 500 pixels by 500 pixels we'll pull off the canvas attribute and then return it and we'll see that we have a 500 pixel canvas now in our notebook cool shrink it down a little bit let's make it 400 and let's start to draw with it so the first thing we're going to do is draw the globe we'll start by by drawing the ocean underneath and then we'll draw the land on top so we'll set the line width of our canvas object to 15 fill it with some lovely light blue and then create a path that draws a circle and the circle will be centered at the middle of the canvas so that's as divided by 2 and then it will have it'll have the radius and we'll draw an arc from 0 to 2 pi so that'll be a full circle and we'll fill it and we'll stroke it and then we'll see that I forgot to define radius so let's make the radius be the size of the canvas divided by 2 and we have our nice Alice blue globe centered with the radius being half the width of the canvas all right that's step one now let's draw some land so in order to draw the land we're gonna need to do a d3 projection will use a geo orthographic which will make it look like we're looking at the globe from outer space we're gonna scale it down to the radius of the globe that we're trying to do and we'll move it over to the center of the screen and that that's our projection right there and then we'll make a path generator from d3 a geo path and then we're gonna tell that path to use that projection in that context now we've got our we've got our projection and we can proceed to draw the countries that we loaded earlier so we'll change the line width to make it a little bit thinner and change the color instead of blue will draw sort of a whitish little off-white color and then we'll draw the the world that we loaded in with the fetch API will begin the path will use the d3 geo path and then fill it and Stroke it and wallah we've got our countries but it looks like I made a typo fillStyle was with an I there you go fix the typo and you can see the difference in colors so we have our little d3 sketch being rendered to a canvas here the next thing we're going to do is to draw some earthquakes so in order to draw earthquakes we'll adjust the size of the world and we'll need to make a function for telling us how big those earthquakes should be drawn all we have right now is magnitude as numbers and their latitude and longitude so let's make us a function that gives us the size of the quake radius and pixels based on its magnitude these are quake magnitude So we'll use a square root scale and we'll give it just a starter domain and range and then we'll return a function here that uses that scale to compute the size of an earthquake based on a single quake object so if you pass in a quake let's say that you scale that quake and we can look down in our example quake and see that it's got a magnitude property so that one's 46 so we're gonna we're gonna do a little exponential sort of square root wrong to get a nice magnitude scale because earthquake magnitudes are are very nonlinear in their force and that will be our quick radius function so you can see the value of that cell is a function that takes a quake and it's going to return that radius so it's time to draw the quakes to do this all we have to do is set a color will make the quicks red to start and then we'll set the radius of the earthquake to be that function passing in passing in a quick object and getting back that radius value and then for each earthquake in the data set we will draw that earthquake will begin a path and then will path it pass the quake and then fill it we don't need lines around them we don't need to stroke it there you go a whole bunch of red earthquakes positioned on the d3 globe

This isn't really satisfactory the earthquakes are a little bit overlapping and bright red so let's change the opacity on them instead of just being the string red as the color let's use d3 color set it to red and then we'll change the opacity a little bit and let's make them 025 alpha so that they oh they can overlap and you can see where you have a whole bunch of quakes in one spot now this isn't quite good enough either because the world is stuck in space at 0 degrees of longitude so let's rotate the projection and let's rotate it first by 90 degrees you can see now the Americas we can do 190 and go over into Australia but let's take that value and make it a live variable that we can control so instead of rotating by 90 we'll create a slider down here I'll say I'm going to have a view of rotation is the standard library function called DOMrange which gives you an HTML range input will go from 0 degrees to 360 degrees and that gives me a slider that values from 0 to 360 and now I'll use the value of that slider which is rotation and you can see that as that value changes the code is re-executed and you get a new drawing and notice what i don't have to do here – I don't have to reinstantiate or reload the page or adjust my definition of the function and we can do the same thing for the earthquake size so here we have quake size as a value that goes from 0 to 12 and we'll use that in the quake radius function to say that the range goes from 0 to quake size and you can see without changing anything the chart is updating with sort of dynamically sized earthquakes and it doesn't just work for a number of values it works for any value so let's change the color as well we'll use a a DOM input a color input which is a color picker in the browser and and let's change our sketch to use quake color instead of red so that'll be a color string and now we can use the color picker and adjust our earthquake colors and our size and rotation so I hope you enjoyed that there are lots of other examples of visualizations data analysis and generative art up on the observable website that you can fork and tinker around with and if any of that was too confusing or if there was too much magic going on I encourage you to check out the introduction series of notebooks that walks you through what makes the Observable runtime different than just a regular JavaScript and introduces you to some of the standard library features that can help so cheers from all of us at ObservableHQcom we're certainly having a lot of fun with this and are looking forward to seeing what you make!

>> GOOD MORNING, DAVE THE WARNINGS EXTEND THROUGH BRITISH COLUMBIA AND ALL THE WAY DOWN TO SAN DIEGO IT WOULD TAKE A LONGER TIME FOR THE WAVES TO ARRIVE WHAT DO WE HAVE? A 79

IT WAS DOWN FROM ORIGINALLY WHICH WAS 82 A GREAT EARTHQUAKE THAT DOESN'T SOUND A LOT, BUT IN EARTHQUAKE WORLD IT IS AS FAR AS THE MAGNITUDE THE DEPTH IS IMPORTANT

YOU DON'T WANT A SHALLOW DEPTH 15 MILES IS SHALLOW THAT IS IMPORTANT THE DISPLACEMENT OF THE WATER WITH THAT ENERGY DOESN'T HAVE MUCH TO TRAVEL THE SURFACE WE HAD A BUOY REGISTERING WAVING UP TO 38 FEET

THAT DOESN'T MEAN 38-FEET WAVES ARRIVE TO THE COAST HERE ARE THE WARNINGS THAT EXTEND ACROSS ALASKA AND ALEUTIAN ISLANDS FROM THERE, BEGINNING ACROSS THE UNITED STATES, WHERE WE HAVE THE WATCHES THAT TCONTINUE ALONG TH WEST COAST THIS IS TO PLAY IT SAFE THE BIGGEST THREAT RIGHT NOW IS ACROSS ALASKA

REMEMBER, THE TSUNAMI IS NOT ONE WAVE A SERIES OF WAVES THEY TRAVEL AT A FAST PACE WE ARE TALKING 500 MILES AN HOUR IF THE TSUNAMI HAS BEEN GENERATED AND WE CAN PRETTY MUCH SAY IT HAS AS A RESULT OF THE BUOY, IT DOESN'T TAKE MUCH TIME BECAUSE OF THE EPICENTER AND THE PROXIMITY HOW CLOSE IT WAS TO ALASKA

WE SHOULD GET INFORMATION WITHIN THE NEXT HOUR AS FAR AS WHETHER A TSUNAMI WAVE HAS ARRIVED IN ALASKA AND THIS IS WHAT HAPPENS IN THE NEXT THREE HOURS ANY TSUNAMI WAVES PROPAGATE SOUTH AND IMPACT THE PACIFIC NORTHWEST AND THEY WILL GO TOWARD THE COAST SIX HOURS THE MAIN THREAT IS BECAUSE THIS HAPPENED UNDER WATER, IT IS A TSUNAMI WE ARE NOT CONCERNED AS FAR AS THE SHAKING DAMAGING BUILDINGS IT WAS FAR ENOUGH OFFSHORE

6.1 Magnitude Earthquake Hits Afghanistan and Pakistan

A magnitude 61 earthquake shook Afghanistan and Pakistan, killing at least one person

The US Geological Survey said the Jan 31 quake was centered in northeastern Afghanistan at a depth of over 191 kilometers Tremors could be felt in both the capital cities of Kabul and Islamabad and as far away as India

At least one young girl died and eight other people were injured when roofs collapsed in Pakistan's Balochistan province Meanwhile, a stampede of students trying to get out of a school in the Pakistani city of Peshawar injured four children Three others were injured when a wall collapsed in Afghanistan's Badakhshan province Gul Mohammad Bedar, the deputy governor of Badakhshan said officials are still collecting information from the remote province A magnitude 7
