Earthquake rumblings
I reviewed this very interesting story (“Seismologists in a rumble over quake clusters,” SN: 5/7/11, p. 5) this morning, and it occurred to me that the connection between all of these very severe earthquakes might possibly be the change in weight distribution throughout the planet, resulting from temperature increases due to climate change with the melting of the glaciers: decreased weight where the glaciers were and increased weight of water on the ocean floors.
