The future of earthquakes on both coasts

Professor Steven R. Dunn on WGBY’s Connecting Point.

This summer, California has been rocked by a series of earthquakes, including a 7.1 magnitude quake in July that was the state’s strongest earthquake in 20 years. 

Steven R. Dunn, professor of geology at Mount Holyoke College, was on WGBY-TV’s Connecting Point to talk about the California earthquake and earthquakes on the East Coast. 

“Anything in the range of 7 [magnitude] or higher is a noteworthy earthquake,” Dunn said. 

But on the East Coast, because the continental crust isn’t as broken by faulting as California is, when a 5-magnitude earthquake occurs, “the energy is transmitted much farther and is felt with a harder … jolt,” as was demonstrated by the 2011 earthquake in Virginia. 

“It was felt all along the Eastern Seaboard,” Dunn pointed out.
