Is Miravalles erupting right now?

There is no open NASA EONET event for Miravalles right now. NOAA NCEI dates its most recent eruption to 1900–1963. 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 Miravalles

USGS has no earthquake within 50 km of Miravalles 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 Miravalles

Miravalles is a stratovolcano in Costa Rica, rising to 2,028 m (6,654 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 San José, Alajuela Province, about 23 km N 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, 1159 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 Costa Rica

Costa Rica has 6 volcanoes on this site that erupted since 1900 or are active now, 1 of them with an open NASA activity report today. The closest other one is Rincon de la Vieja, 21 km away.
