Prediction of volcanic activity, and volcanic eruption forecasting, is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption. Of particular importance is the prediction of hazardous eruptions that could lead to catastrophic loss of life, property, and disruption of human activities.
The most dramatic application of tiltmeters is in the area of volcanic eruption prediction. [6] As shown in this figure from the USGS, the main volcano in Hawaii has a pattern of filling the main chamber with magma, and then discharging to a side vent. The graph shows this pattern of swelling of the main chamber (recorded by the tiltmeter ...

Its caldera at the top is a few miles wide and long, and about 300 feet deep. Unlike other volcanoes around the world that can go centuries between eruptions, this one can be measured in years ...
Volcanoes vary greatly in their level of activity, with individual volcanic systems having an eruption recurrence ranging from several times a year to once in tens of thousands of years. [76] Volcanoes are informally described as erupting, active, dormant, or extinct, but the definitions of these terms are not entirely uniform among ...
Researchers have found evidence that suggests a massive volcano collapse off the coast of Africa caused an 800-foot-high megatsunami.

The Mauna Loa eruption occurred in the summit caldera area of the volcano, containing the bulk of lava within the summit area, although lava started flowing downslope in the northeast rift zone ...
