San Miguel (also known as Volcán Chaparrastique) is a stratovolcano in central-eastern El Salvador, approximately 15 kilometres (9.3 mi) southwest of the city of San Miguel. On January 16, 2002, a minor eruption of steam, gas, and ash occurred from the summit crater,^[1] lasting 3 hours but causing no real damage to life or property. Carbon dioxide emissions had been monitored since November 2001, and their steady increase continued to build up until the eruption.^[1]

Twelve years later,^[2] on December 29, 2013, San Miguel erupted at 10:30 local time spewing ash and smoke into the sky, and prompted the evacuation of thousands of people living in a 3 km (1.9 mi) radius around the volcano.^[3] It was preceded and caused by increased seismic activity beginning at 06:30 local time.^[3]
