Two medium intensity seisms were registered in Chile. These quakes are aftershocks of the March 11 Pichilemu earthquake. According to the University of Chile Geological Survey, the first one took place at 9:59 local time (13:59 UTC); its epicenter was located 17 kilometers northeast of Pichilemu, with a magnitude of 4.7. It lasted about ten seconds. The second aftershock had a magnitude of 5.1, and occurred at the 10:57 local time (14:57 UTC), with its epicenter located 15 kilometers north of Cobquecura.

The National Emergencies Office graded the scale of the seisms on the Mercalli scale, which attempts to quantify the amount of physical damage caused by an earthquake. The intensities of the smaller aftershock were determined to be V in Pichilemu, III in Talca and II in San Fernando, while the larger 5.1 magnitude earthquake only hit IV in Pichilemu, but registered a IV in Talca as well, due to its closer proximity to that city.

Thursday morning the Municipality of Pichilemu posted a letter via Facebook to all those affected by the February 27 and March 11 earthquakes in the surrounding areas of Pichilemu, like Ciruelos, Alto Ramírez, and others. However, they didn’t name the village of Espinillo. The mayor of Pichilemu, Roberto Córdova, was criticized for not giving aid to the village. Córdova responded that he was “doing his best to aid [the surrounding areas]. [The Municipality] is going to replace the [balustrades] destroyed by the 11 March earthquake,” and “these places are receiving the aid they require.”
