Summary

Masaya volcano in Nicaragua has been reported producing volcanic ash clouds observed at the surface and up to about flight level 080, drifting west, northwest and southwest at 6 to 20 knots, with forecasts of continued ash at similar levels. Slight changes in the terrain around the volcano were observed. Satellite radar data from 2018 to 2024, reported in Geophysical Research Letters by a Penn State-led team, indicate at least two magma reservoirs, one filling while another drains, with the ground north of Santiago crater rising while land around the crater sinks. Researchers say no immediate danger to nearby residents was identified, but the findings could improve eruption forecasting. The volcano lies about 12 to 13 miles southeast of Managua, a region home to roughly 2 million people.
