A 1,060-metre (3,480 ft) section of the volcanic cone, estimated to be 0.47 cubic kilometres (0.11 cu mi), was destroyed by the collapse during this prehistoric eruption. [ 4 ] Prior to the eruption in 1951, locals did not know that Mount Lamington is an active volcano as the native population had no widespread ancient folklore or stories of ...
Landslides, rock falls, pyroclastic flows, and mud flows (lahars) are example of mass failures of volcanic material before, during, and after eruptions. The most famous volcanic landslide was probably the failure of a bulge that built up from intruding magma before the Mt. St. Helens eruption in 1980, this landslide "uncorked" the shallow ...
Known large eruptions after the Paleogene period (from 66 Mya to 23 Mya) are listed, especially those relating to the Yellowstone hotspot, Santorini caldera, and the Taupō Volcanic Zone. Active volcanoes such as Stromboli , Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear.
A.D. 79: Mount Vesuvius, Italy. Mount Vesuvius has erupted eight times in the last 17,000 years, most recently in 1944, but the big one was in A.D. 17. One of the most violent eruptions in history ...
After the first eruption of Mount St. Helens on May 18, five more explosive eruptions occurred in 1980, including this event on July 22. This eruption sent pumice and ash 6 to 11 miles (10-18 kilometers) into the air, and was visible in Seattle, Washington, 100 miles (160 kilometers) to the north. The view here is from the south.
During a series of eruptions, volcanic ash blackened the sky, buried crops and destroyed homes. Over the course of the year, the island's 11,000 population was forced to evacuate several times.

Ultra-Plinian eruptions are the largest of all volcanic eruptions are more intense, have a higher eruption rate than Plinian ones, form higher eruption columns and may form large calderas. These eruptions produce rhyolitic lava, tephra, pumice and thick pyroclastic flows that cover vast areas and may produce widespread ash-fall deposits.
