## Masaya Volcano Study
Satellite radar observations from January 2018 to February 2024 show ground movements beneath Nicaragua's Masaya volcano.
## Dual Magma Reservoirs
Researchers found a deeper reservoir gaining magma at 3,200 meters and a shallower one losing it at 200 meters.
## Ground Movement Shift
Ground north of Santiago crater moved 3 centimeters away from satellite between 2018 and mid-2022, then reversed direction.
## Volcano Impact
About 2 million people live within 13 miles of Masaya near Nicaragua's capital Managua.
## InSAR Technology
Interferometric synthetic aperture radar tracks surface changes through clouds in tropical areas like Masaya.
## No Immediate Danger
Penn State says their findings do not indicate immediate danger to communities or a future eruption timetable.
## Key takeaway

Satellite radar shows Masaya volcano has two magma reservoirs: one gaining magma deeper underground and another losing it near the surface.
