Arizona Public Media posted the podcast and figures of a lengthy interview I had with them recently on seismicity and earthquake hazards in Arizona.
I was on the road when it was first broadcast but started getting emails from friends and colleagues who heard it Friday morning. The video below was compiled by AZGS staff using a catalog of earthquakes going back to 1852. The apparent increase in earthquakes over time is due to a combination of more and better instruments detecting remote and small events around the state and our seismologist pouring over the records to identify events that would have been overlooked in the past.
