A series of moderate earthquakes have rippled up and down the northern coastline of Chile over the last 24 hours. The strongest of the 4 earthquakes erupting today was a 5.2 magnitude earthquake that struck near the coastal region of Antofagasta. The earthquakes are an indication of mounting tension on the Nazca plate that has been exacerbated by recent quakes on the neighboring Cocos plate in Costa Rica and Revilla Gigedo Islands.
