This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536); its effect on the climate may have been exacerbated by the 1814 eruption of Mayon in the Philippines. The significant amount of volcanic ash and gases released into the atmosphere blocked sunlight, leading to global cooling.
"Blue lava" as seen at night on Kawah Ijen, in Indonesia. Blue lava, also known as (Indonesian: Api Biru), [1] and simply referred to as blue fire or sulfur fire, is a phenomenon that occurs when sulfur burns. It is an electric-blue flame that has the illusory appearance of lava.
Past eruptions reveal multiple mudflows. Lahars typically occur during volcanic eruptions but also can be caused by landslides and earthquakes. Geologists have found evidence that at least 11 ...
Vulcanian eruptions display several common characteristics. The mass of rock ejected during the eruption is usually between 10 2 and 10 6 tonnes [1] and contains a high proportion of non-juvenile material (> 50%). During active periods of volcanic activity, intervals between explosions vary from less than 1 minute (e.g. Anak Krakatoa) to about ...
More huge explosions rocked the island of St. Vincent Monday and Tuesday mornings as the La Soufrière volcano continued erupting. On Monday, the volcano spewed a tremendous amount of ash and hot ...
The volcanic eruption is Iceland’s fifth in three years, and second in less than a month. An eruption on Dec. 18 saw semi-molten rock projected into the air from a 2.5 miles long crack near ...
The mechanics of a Peléan eruption are very similar to that of a Vulcanian eruption, except that in Peléan eruptions the volcano's structure is able to withstand more pressure, hence the eruption occurs as one large explosion rather than several smaller ones. [34] Volcanoes known to have Peléan activity include: Mount Pelée, Martinique.
Other parts of the country have more powerful volcanoes. In 2010, ash clouds from eruptions at Eyafjallajokull in the south of Iceland spread over large parts of Europe, grounding some 100,000 ...
