Volcanoes can erupt suddenly, but satellite technology now detects hidden ground shifts and heat changes. This helps scientists monitor remote volcanoes where ground sensors are scarce. These advanced ...

Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and upper mantle that fit together like puzzle pieces. Think of these plates as massive rafts floating ...

When volcanoes are preparing to erupt, scientists rely on typical signs to warn people living nearby: deformation of the ground and earthquakes, caused by underground chambers filling up with magma ...
