A volcanic arc (also known as a magmatic arc [1]: 6.2 ) is a belt of volcanoes formed above a subducting oceanic tectonic plate, [2] with the belt arranged in an arc shape as seen from above. Volcanic arcs typically parallel an oceanic trench , with the arc located further from the subducting plate than the trench.
The Bismarck volcanic arc, New Britain, and the TaupÅ Volcanic Zone, New Zealand, appear often too. In addition to the events listed below, there are many examples of eruptions in the Holocene on the Kamchatka Peninsula, [3] which are described in a supplemental table by Peter Ward. [4]
The Cascade Arc includes nearly 20 major volcanoes, among a total of over 4,000 separate volcanic vents including numerous stratovolcanoes, shield volcanoes, lava domes, and cinder cones, along with a few isolated examples of rarer volcanic forms such as tuyas. Volcanism in the arc began about 37 million years ago; however, most of the present ...
A.D. 79: Mount Vesuvius, Italy. Mount Vesuvius has erupted eight times in the last 17,000 years, most recently in 1944, but the big one was in A.D. 17. One of the most violent eruptions in history ...

First: volcanic arc, volcanic belt and volcanic zone. Second: volcanic area, caldera cluster and caldera complex. 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.
According to the U.S. Geological Survey, there are around 1,350 potentially active volcanoes around the world outside of the continuous range of volcanoes as part of the Mid-Atlantic Ridge. In the ...
