will provide California, Oregon, and Washington with advanced warning of potentially
damaging shaking. The hopes for early warning systems are high, but the reality of what
can be expected from earthquake early warning is nuanced. Earthquakes don’t happen
in an instant and don’t tell us how big they will become. This means that any forecasts
that we make will be imperfect, and the amount of warning will be short: in many cases,
only a few seconds of warning will be possible. In spite of these limitations, there could
still be significant value to earthquake early warning, especially for people who are
willing to adopt a “better safe than sorry” strategy of taking protective action for
earthquakes that have only a small chance of causing damage. What kind of warning
system would you prefer? One that issues alerts for weak shaking, but also sends alerts
for many events that do not go on to produce strong shaking? Or an earthquake early
warning system that issues alerts only once ground shaking is expected to be
damaging, but there is an increased chance that the alerts could be issued too late?
During this talk, you will discover how an earthquake early warning system works, how
warnings are issued and how much warning is possible.
