what type of boundary was the mexico earthquake?
transform - style fault
chile has a long history of massive earthquakes, including the 2010 m 8.8 maule earthquake in central chile, which ruptured a ~400 km long section of the plate boundary immediately south of this 2017 event. the april 24, 2017 earthquake lies close to where the juan fernández ridge enters the subduction zone, in a section of the plate boundary that ruptured in a m 8.0 earthquake in march 1985, and previously in the 1906 m 8.2 valparaiso earthquake (reported by some to be as large as m 8.6). to the north of the juan fernandez ridge, the subduction zone last ruptured in the m 8.3 illapel earthquake in september 2015. this subduction zone also hosted the largest earthquake on record, the 1960 m 9.5 earthquake in southern chile. over the century prior to the april 24, 2017 earthquake, the region within 400 km of this event has hosted 19 m 7+ earthquakes. prior to the april 24 m 6.9 event, the region immediately surrounding this earthquake hosted 9 other events of m 4.5 or larger over the preceding 2 days, including a m 5.9 earthquake on april 23, 2017. the 6.9 shock was also preceded by 4 seconds by a m~4 foreshock. within an hour of the m 6.9 earthquake, 4 aftershocks of m 4.7-5.4 had been located.
