Earthquakes come in species, says Greg Beroza, professor of geophysics at Stanford and an expert in seismology.
There are, of course, the well-known sudden shocks, but there are also “slow earthquakes” that transpire imperceptibly in contrast to the obvious temblors, but which can measure 7 on the Richter Scale or more — a major quake by any standard.
Beroza knows about slow and other species of earthquakes because of a recent explosion in the availability of seismic data recorded by an expansive network of sensors throughout California and elsewhere around the world. One hundred times each second, 24 hours a day, every day, each of these sensors records seismic data. What they reveal is reshaping our understanding of earthquakes. The goal, he says, is not necessarily to predict earthquakes — an ideal that may never be achieved — but simply to understand them better. Beroza says that data can help prepare us for “The Big One.” Join host Russ Altman and earthquake expert Greg Beroza for a deeper look at the evolving and expanding science of seismology.
