Aftermath of the 2016 magnitude 7.8 Pedernales earthquake in Ecuador

The recent magnitude 7.8 Pedernales earthquake in Ecuador killed nearly 700 people and caused widespread destruction. Nocquet et al. also thought it looked rather familiar. The earthquake may have ruptured at least part of the same fault as a magnitude 7.8 earthquake that occurred in 1942. The repeat points to an earthquake supercycle and the potential for much larger earthquakes than expected from the long-term accumulation of energy along megathrust faults.
