we have seismometers all over that area. what did they tell you? we know there have been at least four or five after shocks that have happened? that s right. our sensors recorded the main shock this morning magnitude 6.4 that occurred just outside of ridgecrest. those are probably felt. and then nine of magnitude four or larger. those will shake up people close to the epicenter. interesting for folks, they don t realize after that large one happens, there could be
6.2 producing energy, and the warning came through. do we have a time of how much warning we got in pasadena? and the final magnitude, of course okay, so in los angeles there were a 48-second warning that was the shaking was arriving. obviously it was not damaging shaking. that s one of the down sides to this only approach we have. the farther away you are the more warning you get and the less likely there is to be damage. and there are censors in satellites? how do we ever know there s an earthquake? we have censors called seismometers distributed around california. we ve recorded about 500 censors seismic network and they are distributed widely so we can try and catch them. as soon as we get enough nearby we can see that an earthquake is under way and we send that
experiments on the slopes and continents. into the great white yonder antarctica the world s biggest expanse of ice and the seventh continent in places the ice is four kilometers think more than two dozen countries are conducting research here at about eighty research stations. germany s noire meyers three is one of them the antarctic offers a unique environment the world s greatest quantity of fresh waters here frozen solid neumeier three sits atop sixteen hydraulic stilts they keep it from sinking into the snow to be crushed like some of its forerunners. here outside the temperature is minus fifty degrees celsius but that doesn t stop the researchers though they measure the sounds of the antarctic ocean and movements in the earth using seismometers. they also collect data
that deadly wave hurtling toward the coasts on both sides of the strait. now the authorities say that their seismometers, their detectors were not rigged basically to detect something of this magnitude. that they re set up to detect earthquakes of 5.0 magnitude or more, and this was actually much lower if you can believe it. so they re adjusting those sensors. they re also starting to test their siren early warning system. take a listen. [ siren ] now some of this is a little bit too little too late because indonesia is vulnerable to tsunamis. there was a horrific tsunami in 2004 that killed hundreds of thousands of people in indonesia and across southeast asia. actually this is the 14-year anniversary of that. a number of countries donated to
