Is Orosi erupting right now?

NASA's Earth Observatory Natural Event Tracker (EONET) has an open volcanic event for Orosi, last updated Apr 27, 2026 (182 days ago). EONET opens an event when agencies such as the Smithsonian Global Volcanism Program report eruptive activity or unrest, and closes it when activity ends.

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 Orosi

USGS has no earthquake within 50 km of Orosi 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 Orosi

Orosi is a stratovolcano in Costa Rica, rising to 1,659 m (5,443 ft). NOAA NCEI classes its eruptive history as "Uncertain".

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 37 km E 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, 1128 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. The closest other one is Rincon de la Vieja, 23 km away.
