At 07:35:33 UTC (03:35:33 local time) on the 3rd of June 2020 a magnitude 6.8 earthquake struck northern Chile (see map below). The earthquake occurred at a depth of 87 km, locating approximately 200 km east of the city of Antofagasta. Chile experiences very high rates of seismic activity due to its location along the boundary of the Nazca and South American tectonic plates. In addition, the depths at which earthquakes occur in Chile varies greatly, with shallower events occurring along the coast in the west, and deeper events occurring in the east. The largest earthquake recorded in the modern era of instrumental seismology, the M9.5 Valdivia earthquake, occurred in southern Chile in 1960.
The earthquake was recorded at seismic stations worldwide, including stations of the Irish National Seismic Network (INSN), see seismic waveforms below (select figure to enlarge).
