Worldwide Surge in ‘Great’ Earthquakes Seen in Past 10 Years
WASHINGTON D.C. (Worthy News)– The annual number of “great” earthquakes nearly tripled over the last decade, providing a reminder to Americans that unruptured faults like those in the northwest United States might be due for a Big One, NBC News reported.
Between 2004 and 2014, 18 earthquakes with magnitudes of 8.0 or more rattled subduction zones around the globe. That’s an increase of 265 percent over the average rate of the previous century, which saw 71 great quakes, according to a report to the annual meeting of the Geological Society of America this week in Vancouver, British Columbia.
It’s clear that recent “great” earthquakes “triggered” related major quakes, says study author Thorne Lay, distinguished professor of earth and planetary sciences at the University of California, Santa Cruz. — [wp_colorbox_media url=”http://www.nbcnews.com/science/science-news/worldwide-surge-great-earthquakes-seen-past-10-years-n233661″ type=”iframe” hyperlink=”Source”]
