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.
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 caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
A value of 0 is given for non-explosive eruptions, defined as less than 10,000 m 3 (350,000 cu ft) of tephra ejected; and 8 representing a supervolcanic eruption that can eject 1.0 × 10 12 m 3 (240 cubic miles) of tephra and have a cloud column height of over 20 km (66,000 ft). The scale is logarithmic, with each interval on the scale ...
The Weekly Volcanic Activity Report [1] is a cooperative project between the Smithsonian's Global Volcanism Program and the United States Geological Survey's Volcano Hazards Program. Notices of volcanic activity posted on the report website are preliminary and subject to change as events are studied in more detail.

Third: volcanic field, volcanic system and volcanic center. A volcanic field is a localized area of the Earth's crust that is prone to localized volcanic activity. A volcanic group (aka a volcanic complex) is a collection of related volcanoes or volcanic landforms. Neutral: volcanic cluster and volcanic locus.
"Seismic activity has increased in Bardarbunga in recent months," it said, with Tuesday's earthquake swarm the largest since Bardarbunga's last eruption in 2014-2015 which lasted six months ...
