When aftershocks are detected, we will update this section.What are aftershocks?Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.[More info]What about this quake?Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface area of approximately 6 km2 (2 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 4 km (3 mi).[More info]Recorded aftershocks, latest first (0 quake)May 15, 2026 09:59 pm (Santiago)28 minutes ago4.8133 km0 km - This quake85 km NE of Calama, Provincia de El Loa, Region de Antofagasta, ChileMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 1,400 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.04 quakes per year (or 1 quake every 25 years)Mag. 6 or higher: 0.29 quakes per year (or 1 quake every 3.4 years)Mag. 5 or higher: 4.5 quakes per yearMag. 4 or higher: 93 quakes per year (or 7.8 quakes per month)Mag. 3 or higher: 623 quakes per year (or 52 quakes per month)Mag. 2 or higher: 1,400 quakes per year (or 3.9 quakes per day)Mag. 1 or higher: 1,400 quakes per year (or 3.9 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 5 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 25 to 30 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeThe earthquake occurred 11 weeks after a magnitude 5.1 earthquake had hit on Sunday, Mar 1, 2026, at 05:03 pm local time (America/Santiago GMT -3) in 44 km (27 mi) distance to the southwest:Mag. 5.1 earthquake Provincia de El Loa - Tarapacá, Chile - Mar 1, 2026 - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 7.4.
