The World’s Most Explosive Volcanoes; A Top 10 List

Описание: A number of volcanoes are quite famous for their large explosive eruptions. Yet, many of these volcanoes such as Krakatau, Mount Tambora, or the Yellowstone supervolcano are not the consistently explosive in recent times. This video will disuss the 10 volcanoes which since the end of the last ice age have produced the most eruptions similar in size or larger than the 1980 eruption of Mount Saint Helens. Volcanoes on this list include the Taupo supervolcano, Vesuvius, and Mount Saint Helens.

Key for volcano color codes shown in this video (this is only if they do not represent official alert levels from local government / volcanological agencies):
GREEN - Normal volcanic activity, very low chance of an eruption.
YELLOW - Unusual levels of volcanic activity, potential changes at the volcano, increased risk of an eruption.
ORANGE - High volcanic unrest, this can mean a volcano is about to erupt or could erupt with very little warning.
RED - The volcano is erupting.
