Did you know that probability of a magnitude 6.7 or greater earthquake in the Greater Bay Area in the next 30 years is 63%, or about 2 out of 3? We will see what an earthquake in the Bay Area would look like and try to understand its effects. Just like an earthquake, a nuclear test can cause seismic disturbances that are recorded at monitoring stations around the world. We will learn how seismologists tell the difference between these two sources by sleuthing seismic signals.
