Geodetic techniques have been considered a seminal part of volcano monitoring and eruption forecasting for decades. Ground deformation and gravity are used to determine mass change below active ...

New research revealed that a volcano on the moon erupted – and ... Due to the lack of gravity, eruptions do not explode out of the top, but rather spread on the ground level slowly before ...

"These dense structures could be volcanic in origin or could be compact material due to ancient impacts," Root said. "There seems to be no trace of them at the surface. However, through gravity ...
