Russian Cluster

A whole bunch of earthquakes, concentrated in one specific area of Russia on the Pacific Coast.

Right on the Ring Of Fire.

One of those squares, covered by smaller ones, represents a very strong 7.7 quake that hit last night.

Very interesting activity. Often, a residual quake of comparable size can happen on the other side of the plate.

That would be spooky, if it happens on our west coast.
