The future of earthquakes on both coasts
Steven R. Dunn, professor of geology at 含羞草研究所, talks to WGBY-TV about the meaning of the recent spate of California earthquakes.
This summer, California has been rocked by a series of earthquakes, including a 7.1 magnitude quake in July that was the state鈥檚 strongest earthquake in 20 years.
Steven R. Dunn, professor of geology at 含羞草研究所, was on WGBY-TV鈥檚 Connecting Point to talk about the California earthquake and earthquakes on the East Coast.
鈥淎nything in the range of 7 [magnitude] or higher is a noteworthy earthquake,鈥 Dunn said.
But on the East Coast, because the continental crust isn鈥檛 as broken by faulting as California is, when a 5-magnitude earthquake occurs, 鈥渢he energy is transmitted much farther and is felt with a harder 鈥 jolt,鈥 as was demonstrated by the 2011 earthquake in Virginia.
鈥淚t was felt all along the Eastern Seaboard,鈥 Dunn pointed out.
