This devastating earthquake comes as mexican emergency officials are already preparing for hurricane katia. The cat2 storm is expected to make landfall along the gulf coast of mexico tomorrow. People had a short time to get to safety in mexico. It has an earthquake Warning System and this latest quake proves it works. So why doesnt california have one . Ktvus tom vacar joins us now with why were behind places like mexico and japan in Early Warning detection systems. Tom. Reporter its a nationwide system in mexico. Even a few seconds can help people avoid panic, get out of harms way, and function with some warning. Earthquake alarms in mexico city sounded more than a minute before the shaking from a massive 8. 2 magnitude quake that hit southern mexico 500 miles away. Japan also has a nationwide earthquake Warning System. No such truly widespread system is available yet in california. Why . Apparently, not enough dead people. Jennifer strauss of the Uc Berkeley Seismology Lab is also regional coordinator of the california shake alert committee. So they started early and in response to sort of major catastrophic earthquakes. Mexico during the 1985 earthquake and then japan after kobe. Reporter in kobe, 6,000 killed, 40,000 injured and 300,000 displaced. In mexico, at least 10,000 to as many as perhaps 45,000 killed, 30,000 injured, and more than 100,000 displaced. Because were not responding to this mass casualty event, um, it first started with just, can you do it . Reporter she likes to quote former state senator padilla who unsuccessfully introduced legislation to head off a major quake. He said that if a major earthquake happened tomorrow, then major funding for this would be found very quickly. Reporter however, dave kroeker, a sign test at the usgss Earthquake Science Center in menlo park says a quake Warning System is being developed. Were well on our way to a shake alert early Warning System. But theres a lot of work left to do. We have a very different geography here that makes these alert times much shorter. Reporter at the current pace, were five years away from a truly instantaneous alert system. But we need more than 550 more shake sensors along with communications to connect to radios, tvs, smartphones, land lines and computers and sirens. Cost, just 38 million plus 15 million a year to operate and maintain this statewide system. Half that time if the funding were available now. It seems that the money always comes out of the coffers after a disaster. And thats true in earthquakes, as well. Reporter so tom, lets talk more about this early Warning System in mexico. How much time did they have and how does it work . Well, watch this tape. This is a revealing. There is this news anchor onset. He is talking. In the background you can hear this little noise. That noise is the earthquake Warning System. 500 miles away, the sensors detected the earthquake. The sensors are there. Lets see what this sounds like. [ buzzing noise and anchor speaking ] its an earthquake in mexico. This siren is going on throughout the city . Yes. Throughout mexico. Throughout much of mexico, yes. Throughout much of mexico. So this is a long time obviously doing his regular newscast in spanish but having this incredibly long time to say, hey, there is something coming. This earthquake is 500 miles away. It takes time for that shock to travel 500 miles. This is instantaneous. Now he starts feeling the motion. Look what happens. He stays on the set . For now. The lights start waving just a little bit. Now they are starting to pick up the shaking. At one point here, he will walk out of the studio to be safe and then they are going found the camera on the city of mexico city. So here it is. This is just incredible because it gives you a sense of just how long they had to, you know, take cover, run out of the building, get under a desk. Right. And sometimes getting out of the building may not be the best thing because you could come into a brick fall. But now here he is talking now its really starting to shake. You know, i think maybe its time for me to get out of dodge. And so what he is going to do is walk away. Now, lights are going. Take a look at what happens out there in the city. You will see what looks like lightning flashes. Oh, my goodness. Wow those are transformers. Now the shaking is taking place but not nearly as bad because its 50 miles away from an 8 500 miles away from an 8. 2. You can imagine how much that help is. Thats the situation. Near california we have two big differences. We have a different kind of fault. We have these subduction faults which is what they have in mexico. Subduction fault. Two plates coming together and one proceeds under the other. Thats a subduction. The other is called a strike slip. The way that works is, its like this. This is what we have here, a strike slip . We have both but we have more strike slips here. Northern california, we have subductions. So the point is, its a little more difficult proposition for us as californians to be able to handle all of those Different Things and thats why the Technology Takes time. But is that Technology Available . Yes. Is there any, um, technological impedance to this . No. Whats lacking is the political will and the cash to put this thing into service, which could be in service as early as two years. How much is Something Like this to put into service . Reporter 38 million to put it all in service and about 15 million a year to monitor to and to maintain it so that it works all the time. Tom, thats almost nothing. Compared to when you look at what our buckets are, thats just a drop. Isnt that interesting . And remember what i said in the package . Probably havent killed enough people. If you killed, um, hundreds of thousands of people in the united states, then something is going to happen. And as an example, look at what happened in texas. Look whats happening in florida. They have raised billions of dollars in Congress Like that were talking about 38 million. Is there a reluctance to do this . Or well get to it later . Why spent money when you dont have to . The way the government works, unfortunately, is the squeaky wheel, in this case the earthquake fault also get the grease but if and only if theres a lot of damage, unless people say we want it, we want it now and we wont take no for an answer. Tom, thank you. Now to Hurricane Irma. The newest forecast is not good news for florida. Hurricane irma is strengthening and taking aim at the state. A half Million People have been ordered to evacuate. So the interstates as you see here heading north are jam packed with people who are trying to get away from the storm. Gas, bottled water and plywood all in short supply as Hurricane Irma gets closer to landfall in the united states. Where is irma . Chief meterologist bill martin is tracking the storm in the weather center. Its off cuba heading our way. It will be here late in the weekend in the east coast and it is strengthening. Its moving into much higher temperature water. The water its moving into, 88, 89, 90degree water that fuels the hurricane. Theres the current imagery. Winds are 155. Thats down. It was 185 earlier. Its a cat4. When it hits the warmer water, models say it will go back to cat5 as it guess ready to make landfall. Theres a big hurricane. There are a lot of hurricanes two others out in the area but this is the one we have our eyes on. This is a day and a half away from florida. But heres what is most striking about this system. Look at the warnings for florida from tampa south into the everglades, miami all the way north. And those could move up. This thing as it moves onshore looks as though the path is going to be and this is almost a worstcase scenario. Its very close to worstcase scenario because youre going to bring the eye wall right here turns into a category 5 just offshore. But youre going to bring the eye wall onshore. Youre also going to put miami in the right front quadrant of this storm. Heres the storm. Heres the right front, right . So right here. Thats where the strongest dynamics are. So as we watch this system begin to get ready to move onshore, you can time it out. Hopefully, as it moves past cuba, it gets friction in cuba the force of the mountains this could weaken it a little bit. Thats one of the hopes is this thing diverges and hits land and slows it down but then you see the model picks it up here as a cat5 just offshore. So this is going to change again. Its been changing i have been watching these models all dame. They have been changing literally every couple hours. But most of the models, here they are now, this is the spaghetti plot, they are all kind of agreeing on this. Right now, they agreed on a little bit further about 70 miles east last night. So we are going to be tracking this for you. Its a big story and its developing. Can i ask you a quick question . Whats that one line there all the way on the left . Thats one of the models. It has it going into the gulf . Thats a model saying our solution, all the models have different inputs but they are essentially the same. Frank is referring to this model here. That could be a problem because this thing could linger for a little bit, strengthen again. Thats just one of the models. Its an outlier. So when we look at these models thats where most of them are. But well watch it and tonight it will change. How long once it does make landfall, how long could it sit . It looks like its going right up the gut of florida. It is. Thats the worstcase scenario. A lot of folks have evacuated into orlando which is well to the north. This storm because its moving over such lowlying land in south florida, it could be a category 2 hurricane when it hits orlando. But its not going to fall apart right away. South florida isnt going to break it up quick enough. Northern florida will because of the topography. Theres a lot of evacuees in orlando. Thats where people went. Theres definitely a lot more to talk about with this. Bill, thank you. As Hurricane Irma barrels toward florida the death toll in the caribbean is growing. 22 people are now confirmed dead from the storm. In florida, governor rick scott is warning people who live in south florida to get out while they still can. Ktvus alyana gomez is following the latest developments for us from our newsroom. Alyana. Reporter thats right, julie. Governor scott is telling residents in south florida they now have just hours left to safely evacuate. 5 1 2 Million People have been asked to evacuate already and irma is expected to make landfall there late tomorrow. Now, there are mandatory evacuations in effect for parts of southeast florida and the freeways are clogged with traffic as people make their way out of town. For those insisting on staying behind, Governor Scott is warning that irma will be more powerful than hurricane andrew which was the most destructive storm to hit florida ever in 1992. Irma is downgraded to a higher end of cat4 and are expecting the winds to pick up and to be back to cat5 when it makes landfall with winds over 150 miles per hour. Its also expected to bring with it a 12foot storm surge. The majority of florida will have major hurricane impacts with deadly storm surge and lifethreatening winds. We expect this along the entire east coast and the entire west coast. Reporter National Guard troops are already being positioned to provide help and plans have already been announced for nighttime curfews in some communities. In miami, there are long lines at emergency shelters and many of them are filling up. The Associated Press is reporting that authorities in florida are forcing Homeless People into shelters against their will. The ap reports police are working with social workers and psychiatrists to get them off the streets where they could die if they stay outside in the storm. The hurricane is now making its way past the bahamas and cuba and were seeing video from cuba. The large storm surge there. The footage from the turks Caicos Islands shows widespread destruction. Take a look at that there. With the death toll in the caribbean now at 22. This afternoon, the National Weather service in key west tweeted this. Quote, this is as real as it gets. Nowhere in the florida keys will be safe. You still have time to evacuate. And it appears from aerial footage that many people are take that advice and getting out of the florida keys and making their way to the mainland. Now, all of this is happening as islands in the caribbean are bracing for yet another storm, hurricane jose, expected to make landfall there tomorrow packing 150mileperhour winds. Is it still too late for people who are hoping to get out of town at the miami airport . Reporter its last flight is 9 30 eastern time tonight but that doesnt mean theres any space. Some of my family had some really big challenges trying to book a flight. Some of them are trying to come here to San Francisco and said they just couldnt find any more flights and some of them really werent, um, affordable, either. So they have gone to shelters there. So the flight situation is pretty challenging. There are no flights scheduled for this weekend. All right. Alyana gomez in the newsroom tonight, thank you. And coming up at 5 30, well take you live to miami which is a virtual ghost town right now as florida braces for irma. A frightening phone call for a Silicon Valley ceo. The caller claimed to be holding his sister for ransom and said he had proof. New information on a very scary scam. And the university of california system takes on President Trump and his decision on daca. Why the lawsuit means so much to the leader of the university. Lets bring our chief meterologist bill martin back. You to, again we have so much going on here with the hurricanes. We have local weather too. We do. A week ago it was 106 in San Francisco. What a difference a week makes. Temperatures mild. Temperatures tomorrow warmer. Towards the weekend warmer still. As you look at the satellite loop theres fog all along the coast right here and, i dont know, not a bad day. We had more sunshine today than yesterday, less humidity and the smoke is gone. As you look at the fog along the coast, there it is, and there it stays. I think it will be patchy fog next couple of days. Theres no reason for it not to be there. But the weekend looks like its going to be nice. A little warmer. You can see up in the hills these lightning strikes continuing up around lake tahoe up around truckee up around kirkwood, south lake tahoe, around yosemite, as well. So if you are going to the mountains this weekend, some more thundershowers possible. These are the highs which are running warmer than they were last night at this time by a few degrees. So remember yesterday . Yesterday was cool. I mean, we had highs it was cool. But it was cooler. Highs were in the 70s and 60s for most of our spots. So right now its 84 in fairfield. Great shot. Its looking straight out to the west now. Theres the fog bank. Well warm up this weekend. Fog stays at the coast. Doesnt get well inland. So temperatures warm on your bay area saturday. They warm a little bit on sun, too. It will be the warmest day. Theres your saturday forecast. Lunchtime 80 in fremont. 92 for daytime high towards the Livermore Valley and the warmer spots. Sunday, well see maybe some mid to upper 90s. So if we break it down a little, theres the fog footprint for the morning. The warmer at the coast. Its the beauty of Stinson Beach because the northwest wind shears off the fog and pushes it away. Inside point reyes, you get a lot of clearing. Thats why places like Half Moon Bay get so much fog because the wind blows it right in. So theres the forecast for your saturday. Sunday is going to be warmer still. Got a 9er game on sunday. A bears cal playing on saturday. I dont know if stanford is home or not. Ill look into that. But a lot going on. Weather looks good. Sunday is hotter. Well talk about that next. Demonstrators protesting the urban shield program today. The 48hour s. W. A. T. Training program is just starting this weekend. The people taking part in urban shield say the training is critical and that every scenario is based on a real life event. Opponents say it leads to a more militarized police force.
