Iceland is a fabulous showcase for volcanoes. The easily accessible locations to view explosions of fiery lava and ash provide unusual opportunities for volcano-appreciators of all types, giving them ringside seats for the action. In the past few decades, there have been several spectacular volcanic performances. Attempting to control volcanoes is a major challenge, although people have tried, and even achieved success.
The volcano recently erupting in Africa–Mount Nyiragongo–is one of the most active on our planet. Eruptions in 1977, 2002 and now beginning in May 2021, have resulted in a significant number of fatalities and extensive damage in the nearby and densely populated city of Goma. If scientists were calling the shots, they would relocate Goma and designate the region beneath this active volcano as a national park.
A huge volcano erupted violently about 760,000 years ago on the eastern side of the Sierra Nevada, forming a large depression called the Long Valley Caldera. This “super-eruption” was estimated to be more than 2,000 times larger than the 1980 eruption of Mt St Helens...Today, the Mammoth Lakes resort area is on the western edge of the ancient caldera.
