Getting close to active or erupting volcanoes can be dangerous. But for Michael Rampino it’s all in a day’s work. Rampino is a volcanologist a scientist who studies volcanoes and how they affect our planet. Rampino has been close to red-hot lava flows (熔岩流) in Hawaii and explosive...
However, we quickly realize that some of the most known active volcanoes are missing: Kilauea, Stromboli, Yasur and many others. The reason is that in addition to the above list there are about 20 volcanoes world-wide in near-constant (persistent) activity, which are not listed because the ...
For this reason, there are numerous types of lava, lava flows, and volcanoes. For instance, volcano categories include lava domes, cryptodomes, shield volcanoes, volcanic cones, composite volcanoes, and the list goes on. The erupting lava can either be in the form of thick clouds or fragment...
Of the 500 or so active volcanoes, around 10 are erupting on any given day. For the most part, these eruptions are small and well-contained, so they don't threaten life and limb. From time to time, however, we get a major eruption that either takes lives or, more often, devours pro...

Although many volcanoes are mountainous in shape, a volcano can exist in nearly any form, including volcanic vents on the ocean floor, ice volcanoes, which have been found on a variety of other planets, and volcanoes that are simply a crater in the ground. Despite the variances in the ...
