San Salvador volcano eruptions

stratovolcano 1893 m / 6,211 ft
El Salvador, 13.73°N / -89.29°W
Eruption list: 1917, 1806 (?), 1671, 1658, 1572 ± 2, ?1200, 640 AD ± 30 years


1999 unrest
A small seismic swarm occurred in August 1999, when volcano-tectonic earthquakes about 5 km from the crater were detected. No other signs of unrest were noted.

1917 eruption
Eruption from Boqueroncito (from Kumar, 1957)
Eruption from Boqueroncito (from Kumar, 1957)
The last eruption of San Salvador volcano began on 6 June 1917 following strong and destructive earthquakes lasting for 2 hours. The eruption consisted of an effusive fissure eruption on the NW flank followed by a moderately explosive summit eruption (similar, but smaller in scale, to the Eyafjallajökull eruption in 2010).
The effusive phase produced a large aa lava flow on the NW flank, left a row of cinder cones on the eruptive fissure, and lasted about a week. The second phase started simultaneously with the waning of the waning of the first phase from a fissure vent inside the summit crater. It quickly evaporated a former 400 m wide lake and built the small Boqueroncito cinder cone.
