A M~8.3 Chile earthquake has become more likely
Since 22 April 2017, an earthquake swarm has been in progress offshore the port city of Valparaíso, which has been widely felt in Chile’s capital, Santiago. This sequence began with a M=6.0, and was followed two days later on 24 April, by a M=6.9 earthquake in the same swarm cluster. Today there were M=5.8 and M=5.9 earthquakes. What are the implications of the swarm, in light of historical earthquakes in the region, for what may happen next?
