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.
Volcano and Earth movement monitoring then used the water-tube, long baseline tiltmeter. [2] In 1919, the physicist, Albert A. Michelson , noted that the most favorable arrangement to obtain high sensitivity and immunity from temperature perturbations is to use the equipotential surface defined by water in a buried half-filled water pipe.

About 40 eruptions of VEI-8 magnitude within the last 132 million years have been identified, of which 30 occurred in the past 36 million years. Considering the estimated frequency is on the order of once in 50,000 years, [3] there are likely many such eruptions in the last 132 Mya that are not yet known. Based on incomplete statistics, other ...
Unlike other volcanoes around the world that can go centuries between eruptions, this one can be measured in years. The most recent eruptions occurred in 1998, 2011 and 2015.
A volcanologist, or volcano scientist, is a geologist who focuses on understanding the formation and eruptive activity of volcanoes. [1] Volcanologists frequently visit volcanoes, sometimes active ones, to observe and monitor volcanic eruptions , collect eruptive products including tephra (such as ash or pumice ), rock and lava samples.
Active volcanoes such as Stromboli, Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear. Some dangerous volcanoes in "populated areas" appear many times: Santorini six times, and Yellowstone hotspot 21 times.
The classical world of Greece and the early Roman Empire explained volcanoes as sites of various gods. Greeks considered that Hephaestus, the god of fire, sat below the volcano Etna, forging the weapons of Zeus. The Greek word used to describe volcanoes was etna, or hiera, after Heracles, the son of Zeus.
Super volcano is the term used to describe volcanoes that have gradually over time built up immense amounts of magma and could wreak havoc if ejected onto the planet's surface. And in the heart of ...
