Today’s M=6.6 earthquake shook one of the most seismically active regions on earth.
The Mendocino Triple Junction is one of the most seismically active regions on earth, while the Northern San Andreas is extremely quiet.
While most people think of volcanoes when they think Hawaii, the region is also very seismically active.

At 5:02 Saturday morning, a Magnitude 5.6 earthquake struck 14km NW of Pawnee, Oklahoma. This was a fairly shallow quake occurring about 6.59 km below Earth’s surface, and it caused strong shaking.
Based on early reports, the USGS estimates that there will be no casualties or major damage. However, some injuries or economic losses may still be possible.
It’s been over four months since we wrote about the powerful Kumamoto quake sequence: The 15 April 2016 Mw=6.2 (Mjma 6.5) Kumamoto, Japan, shock, which was succeeded 28 hours later by the very damaging Mw=7.0 (Mjma 7.3) shock on the same fault system. We can now give you a preview of crucial new discoveries by Japanese and other researchers.
At 4:37 am Friday morning, a M=7.1 earthquake struck off the east coast of New Zealand, 166 km northeast of Gisborne. This was a moderately deep quake, occurring about 20 km below Earth’s surface, and it caused moderate to strong shaking on land.
Last week’s M=6.2 Italy earthquake left many parts of the medieval city of Amatrice in ruin. In the old part of the city, most buildings were made of unreinforced masonry, leaving them susceptible to collapse [Guidoboni and Valensise, 2015]. Amatrice was all but destroyed in three large shocks over 19 days in 1703, and so the part of the town that was highly damaged on 24 August 2016 was composed of buildings largely constructed about 300 years ago. In contrast, the newer construction in the east side of the town came through the M=6.2 quake relatively unscathed.
