Sakurajima crisis Volcanic crisis at Sakurajima - updates A strong earthquake swarm and increased inflation were detected in August and triggered authorities to raise the alert level, as volcanologists think that a larger eruption could follow.

Volcanoes of Java Aug. Photos from Kamchatka Kamchatka in Russia's far east is one of world's remotest regions and has an almost unparalleled density of active volcanoes. Look at photos taken during our expeditions from this wonderful corner of the world! But volcanic formations? They can endure for millions of years! Knowing if there still life in them requires hard work, good record-keeping, and above all immense patience. We have written many articles about volcanoes for Universe Today.

Want more resources on the Earth? I would imagine that the hotspot volcanoes are easiest to categorize — they are either active or dormant until they are beyond the hotspot Hawaiian Islands, like the article noted.

This article highlights the differences between active, dormant, and extinct volcanoes. Researchers do not currently agree on an official definition of active volcanoes.

However, they are often considered to include geographic features which have had some activity within the last 10, years. In other words, active volcanoes are those that have erupted since the last ice age. The weakness with this definition, according to critics, is that a volcano may have erupted over the last few thousand years, but is not likely to erupt again soon.

Other definitions of active volcanoes stipulate that the feature must be currently exhibiting some sort of activity, and not limited to eruption. Such activity may include frequent seismic activity as tectonic plates begin shifting around the base of the volcano. This movement may allow the release of significant amounts of carbon dioxide, sulphur dioxide, or other gases into the atmosphere.
