6/17/2015 — Large M7.0 earthquake strikes South-central Mid-Atlantic ridge

A rare, and very large M7.0 earthquake has struck the South Central Mid-Atlantic ridge.

7.0m earthquake mid atlantic june 17 2015


Video report here:


This earthquake started out as a magnitude 6.2, which was then removed from the USGS feeds, and replaced entirely by this M7.0 event.

The European EMSC agency is reporting one single M6.8 event.  Thus this is certainly a USGS upgrade, as opposed to a 2nd earthquake.

This large earthquake activity on the Mid-Atlantic was expected to occur.  A forecast for the Central Mid-Atlantic was issued 7 days ago.

Watch the forecast calling for larger Mid-Atlantic ridge movement here:


In addition to this large earthquake activity, a series of Volcanoes has erupted in the West Pacific over the past day.   These volcanic blasts were also expected to occur, and talked about in the above forecast video.

Mount Bulusan in the Philippines, Mount Sinabung in Indonesia, and Mount Asama in Japan — all three sent off volcanic blasts in the past 24 hours (up to June 17 2015).

Mount Asama in central Japan:
