On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge , such as the Mid-Atlantic Ridge , has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has ...

Volcanic belts are found above zones of unusually high temperature (700 to 1,400 °C (1,292 to 2,552 °F)) where magma is created by partial melting of solid material in the Earth's crust and upper mantle. These areas usually form along tectonic plate boundaries at depths of 10 to 50 kilometres (6.2 to 31.1 mi).

At 5,286 m (17,343 ft), Sangay Volcano is an active stratovolcano in central Ecuador, one of the highest active volcanoes in the world and is one of Ecuador's most active volcanoes. It exhibits mostly strombolian activity; An eruption, which started in 1934, ended in 2011. [73] More recent eruptions have occurred.
An unknown volcano erupted so explosively in 1831 that it cooled Earth’s climate. Now, nearly 200 years later, scientists have identified the “mystery volcano.”
The volcano was dormant for about half of last century, but rumbled back to life with a series of relatively small eruptions beginning in the 1990s. The government ordered evacuations then, and ...
