[ghsc-seminars] GHSC Seminar - Today, Thurs. 2/28 @ 10am - Dave Wald: Earthquake Early Warning

[Rigler, Erin (Josh)]

*Earthquake Early Warning: *
*A Timely Assessment *

*David Wald*
*U.S. Geological Survey *

Earthquake Early Warning (EEW) is coming to the U.S. West Coast. Can it
deliver on what’s been promised? I’ve asked this question, and others, to
many EEW advocates and skeptics alike—among them geophysical and social
scientists, seismic network operators, earthquake engineers, and utility
operators. I’ve explored their science and contemplated their feedback. On
this basis, I believe that EEW should and will be delivered to the public.
Yet, basic seismological principles, substantial lessons learned from the
EEW experience in Japan, and a realistic appraisal of the EEW communication
challenges and possible response actions associated with EEW all point to
more limited opportunities to warn and protect than promised. In short,
potential warning times for the U.S. west coast are less impressive—and
possible mitigation actions are likely to be less effective—than often
purported. What is called for, then, is more transparency and balance in
our EEW discussion: along with its potential, we must depict and present
EEW’s inherent and practical limitations. I will review EEW, describe its
potential benefits and practical limitations, and suggest some potential
ways to better communicate these realities.

* The hour-ish seminar and Q/A will be followed by an optional ½ hour round
table discussion on the topic. Feel free to stay, or head back to work!
