If you want to survive, HOW ARE WE GOING TO PAY FOR IT ALL ? - Senate Ways & Means Cascadia Subduction Zone Presentation Work Session, ...

SUMMARY:  If you want to survive, recognize that at first you will be all alone and uninsured.  We will need to take care of the after-effects of all of this ourselves.
STILL IT GETS PUSHED TO THE END OF A VERY BUSY AGENDA. This requires that we expect more from our leadership and that we elect serious, sober and somber people into office; NOT bratty, cute, entitled STUPID children.  One member of this committee WALKED OUT, even before this presentation had been concluded.

ShakeAlert (www.shakealert.org ) is an experimental earthquake early warning system (EEW) for the West Coast of the United States and the Pacific Northwest.  ShakeAlert is a product of the US Geological Survey and its partners including the California Institute of Technology, University of California, Berkeley, University of Oregon, University of Washington, Eidgenössische Technische Hochschule Zürich (ETH), California Office of Emergency Services, and California Geological Survey. This animation, produced by IRIS in collaboration with University of California, Berkeley, describes how the system uses sensors to detect P and S waves to determine earthquake location and magnitude, and how that information can be sent to ShakeAlert users to give time to Drop, Cover and Hold On.

Typical values for P-wave velocity in earthquakes are in the range 5 to 8 km/s. The precise speed varies according to the region of the Earth's interior, from less than 6 km/s in the Earth's crust to 13.5 km/s in the lower mantle, and 11 km/s through the inner core.
S-wave velocity tends to increase with depth and ranges from approximately 2 to 8 km/s in the Earth's crust, up to 13 km/s.

Dramatic first footage of the earthquake that struck Mexico City on Sep 19th 2017
Wikipedia - The 2017 Puebla earthquake struck at 13:14 CDT (18:14 UTC) on 19 September 2017 with an estimated magnitude of Mw 7.1 and strong shaking for about 20 seconds. Its epicenter was about 55 km (34 mi) south of the city of Puebla. The earthquake caused damage in the Mexican states of Puebla and Morelos and in the Greater Mexico City area, including the collapse of more than 40 buildings.[2][3][4] 370 people were killed by the earthquake and related building collapses, including 228 in Mexico City,[5][6] and more than 6,000 were injured.[7]
The quake coincidentally occurred on the 32nd anniversary of the 1985 Mexico City earthquake, which killed around 10,000 people. The 1985 quake was commemorated, and a national earthquake drill was held, at 11 a.m. local time, just two hours before the 2017 earthquake.[8][9] Twelve days earlier, the even larger 2017 Chiapas earthquake struck 650 km (400 mi) away, off the coast of the state of Chiapas.[10]
