If Yellowstone’s volcano erupted, it would be catastrophic. The eruption would shoot a tower of ash into the air, taller than Mount Everest, covering nearby cities in over a meter of ash and creating giant clouds that would block the sun for decades.
Geologists generally group volcanoes into four main kinds–cinder cones, composite volcanoes, shield volcanoes, and lava domes.
1. Alaska. Alaska is home to the largest number of potentially active volcanoes in the U.S., with 141, according to the Alaska Volcano Observatory. While most of the volcanoes are located in remote areas, a few are near the state’s largest city, Anchorage.

In 1815, Mount Tambora erupted on Sumbawa, an island of modern-day Indonesia. Historians regard it as the volcano eruption with the deadliest known direct impact: roughly 100,000 people died in the immediate aftermath.
Mauna LoaRising gradually to more than 4 km (2.5 mi) above sea level, Hawaii’s Mauna Loa is the largest active volcano on our planet

Volcanoes do not typically occur at transform boundaries. One of the reasons for this is that there is little or no magma available at the plate boundary. The most common magmas at constructive plate margins are the iron/magnesium-rich magmas that produce basalts.
Engineering Volcanoes. Science yearns to discover a means to control or stop volcanic eruptions before they begin. To date there have been no successful efforts to start, stop or reduce a volcanic eruption; however, the ideas exists and discussion is underway.
