Dangerous! Six Volcanoes Across The Globe Are Threatening To Erupt

When you have six volcanoes, and they all bear close watching, you could have some serious worldwide problems on your hands. Out of the hundreds that scientists are watching, there are six that have scientists worried. The supervolcano in Yellowstone Park is, thankfully, not one of those at the moment. One of them, however, is in the United States as you will read below.


The eruption of Mount Agung on the island of Bali has sparked worldwide media interest, yet volcanic eruptions in Indonesia are nothing new. Of the country’s 139 “active” volcanoes, 18 currently have raised alert levels, signifying higher than normal seismic activity, ground deformation or gas emissions. On a global scale, in any week in 2017, there were at least between 14 and 27 volcanoes erupting.

Most observed volcanic activity takes place along the Pacific Ring of Fire, a region around the Pacific Ocean where several tectonic plates meet, causing earthquakes and a chain of what geologists call subduction zone volcanoes. Other eruptions occur at volcanoes within continental interiors such as Ol Doinyo Lengai in Tanzania, or on oceanic islands like Hawaii. Many also take place hidden from view on the sea floor, with some of the most active underwater volcanoes located in the Tonga-Kermadec island arc in the south-west Pacific.

The current eruptions on land range from gentle lava effusions to moderate-sized explosions and are tiny compared to the largest in Earth’s history. Even the 1815 eruption of Mount Tambora, also in Indonesia, arguably the largest eruption in recent recorded history, is dwarfed by super-eruptions in the geological past such as that of Toba volcano on Sumatra some 74,000 years ago. Toba erupted approximately 70 times more magma than Tambora, helped plunge the earth into another ice age and may have even created a genetic bottleneck in ……
