Masaya Volcano Dual Magma Reservoirs Found
Satellite radar reveals two magma reservoirs beneath Nicaragua's Masaya volcano near 2 million people.
In brief
Satellite radar reveals two magma reservoirs beneath Nicaragua's Masaya volcano near 2 million people. Satellite radar shows Masaya volcano has two magma reservoirs: one gaining magma deeper underground and another losing it near the surface. Originally reported by Dallas Express.
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.
The headline
Satellite radar shows Masaya volcano has two magma reservoirs: one gaining magma deeper underground and another losing it near the surface.
