Mid-Atlantic Ridge Jumpy

17 02 2015

While we watch these big quakes off Japan (ENE News report, Quake Watch report) and the 6.7 quake at the bottom of South America, the Mid-Atlantic Ridge is extra jumpy at the same time as Brazil tremors with 1.5-3M smaller quakes.

Earlier we posted about a series of large quake on the Mid-Atlantic Ridge in 2013.

The RSOE map doesn’t get the Brazil info but they have a good map of the ridge.
