Earthquakes as Existential Risks
Earthquakes are not typically considered existential or even global catastrophic risks, and for good reason: they’re localized events. While they may be devastating to the local community, rarely do they impact the whole world. But is there some way an earthquake could become an existential or catastrophic risk? Could a single earthquake put all of humanity at risk? In our increasingly connected world, could an earthquake sufficiently exacerbate a biotech, nuclear or economic hazard, triggering a cascading set of circumstances that could lead to the downfall of modern society?
Seth Baum of the Global Catastrophic Risk Institute and Ariel Conn of FLI consider extreme earthquake scenarios to figure out if there’s any way such a risk is remotely plausible. This podcast was produced in a similar vein to Myth Busters and xkcd’s What If series.
We only consider a few scenarios in this podcast, but we’d love to hear from other people. Do you have ideas for an extreme situation that could transform a locally devastating earthquake into a global calamity?
This episode features insight from seismologist Martin Chapman of Virginia Tech.
Note from FLI: Among our objectives is to inspire discussion and a sharing of ideas. As such, we interview researchers and thought leaders who we believe will help spur discussion within our community. The interviews do not necessarily represent FLI’s opinions or views.
