Is San Salvador erupting right now?

There is no open NASA EONET event for San Salvador right now. NOAA NCEI dates its most recent eruption to 1900–1963, and the last eruption in its significant-eruption database was in 1917. Volcano observatories can raise alert levels before an eruption starts, so check the national observatory for the current alert level.

No satellite thermal hot spot was detected within 10 km of the summit in the latest NASA FIRMS data, so there is no sign of lava at the surface large enough for VIIRS to see (clouds can hide it).

Earthquakes near San Salvador

USGS has no earthquake within 50 km of San Salvador in the past 30 days. Outside the United States USGS mainly lists quakes above about M4, so small volcanic tremors recorded by the local observatory will not appear here.

About San Salvador

San Salvador is a stratovolcano in El Salvador, rising to 1,893 m (6,211 ft). NOAA NCEI classes its eruptive history as "Historical".

Stratovolcanoes are steep cones built from alternating lava and ash layers; their eruptions are often explosive, with ash columns that can reach cruising altitude.

The nearest large town is Santa Tecla, about 6 km S of the summit; 5 other cities lie within 250 km.

Flights and volcanic ash

No major hub airport is within 400 km (the closest is Cancún, 851 km away), but ash clouds from explosive eruptions can drift for thousands of kilometres along flight routes.

Volcanic Ash Advisory Centres (VAACs) issue the official ash advisories that airlines and air traffic control follow.

Other volcanoes in El Salvador

El Salvador has 5 volcanoes on this site that erupted since 1900 or are active now. The closest other one is Izalco, 38 km away.
