On January 7, 2020, Puerto Rico experienced an Mw 6.4 earthquake 8 km offshore the southern coast, near Indios. It followed a series of more than 500 smaller earthquakes and an Mw 5.8 quake one day earlier, which destroyed Punta Ventana, one of Puerto Rico’s most famous rock formations. The event collapsed an elementary school, necessitated hospital patient evacuations, killed one man in his home, and injured several others. In addition, power for most of the island was disrupted. While small earthquakes (Mw≤4) are not uncommon for this area and are regularly detected by the Puerto Rico Seismic Network, events of larger magnitudes are more unusual.
