A large earthquake just hit! Is this the mainshock or a foreshock or an aftershock? Nobody knows until the earthquake shaking starts again in the next day or week. Is another earthquake inevitable? Can the experts predict aftershocks?
During an earthquake, soft story buildings pose an extra risk. Some soft story buildings collapsed in the 1989 Loma Prieta and 1994 Northridge earthquakes. Cities around California are now catching up by adopting soft story ordinances and requiring retrofits. Do you live in a soft-story building?
We get tornado warnings, hurricane warnings, snow storm warnings, but no earthquake warnings. It’s difficult to prepare for something when we don’t know when it is coming. We only know that eventually, an earthquake will happen. Why is this? And is this changing? Can earthquakes be predicted?
Whoa, was that an earthquake last night? Did you check out Nextdoor or Twitter to see if others also woke up? It’s actually good news when earthquakes hit at night instead of during the day. Night earthquakes mean fewer injuries and fewer fatalities. Let’s look into why this is the case.
The 1906 San Francisco earthquake destroyed 28,000 buildings. It left over half the population homeless and claimed the lives of 3,000 people. What did we learn from the earthquake, and what changes did we implement after the earthquake? Have we done enough to prepare for the next big earthquake? In this article, we review discoveries related to geology, earthquake-induced fires, building performance, and the recovery process.
