A volcanic eruption in Italy sent people fleeing Wednesday, with many forced to escape the fiery explosion by boat. The Stromboli volcano, located on the island of Stromboli, near Sicily, began ...
An early stage of the July 12, 2009, eruption of Sarychev volcano, seen from space. Viscous magmas cool beneath the surface before they erupt. As they do this, bubbles exsolve from the magma. Because the magma is viscous, the bubbles remain trapped in the magma. [2] As the magma nears the surface, the bubbles and thus the magma increase in volume.
The video shows August footage from Mount Dukono, an active volcano in Indonesia, not Yellowstone National Park. No evidence supports the post’s claim of a Yellowstone volcanic eruption in ...
As the most active complex volcano in West Sumatra province, and in proximity to populated areas, Mount Marapi is a significant hazard. [5] Since 2011, the volcano has been at the level II (Waspada) of a four-tier alert system set up by the Volcanological Survey of Indonesia. [6] A significant eruption occurred in 1979, [7] killing 60 people. [8]
On 4 November 2024, the volcano spewed molten debris at several villages some 4 km (2.5 mi) away, destroying homes and killing at least nine. [74] The Centre of Volcanology and Geological Hazard Mitigation recommended that a 7 km (4.3 mi) radius around the volcano be evacuated. [75] Seven villages were affected by the eruption. [76]
The explosion was so huge that it penetrated through the overlying seawater and triggered the tsunami. [86] Importantly, the atmospheric waves caused by the explosion coupled to the ocean, generating additional tsunamis at large distances from the volcano; volcanic tsunamis normally do not reach far from the edifice. [87]

On March 27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States.A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place on May 18, 1980, at 8:32 am.
