The National Park Service said the eruption covered an area just shy of the size of Rhode Island. The Usgs said it had spread ash and materials over 1,000 miles, reaching what today is Southern ...
On March 31, 2017, the volcano started to show some activity with ash eruptions. [13] The National Park area opened for visitors was closed from 2009 to 2011. Turrialba in 2005. On January 8, 2010, a phreatic eruption occurred, creating a new opening near the crater on the southwest, and the temperature increased from 200 to 600 °C (392 to ...
Pauahi Crater is a volcanic crater measuring 2,000 ft (610 m) long, up to some 1,300 ft (400 m) across, and 300 ft (91 m) deep in Hawaii Volcanoes National Park at It is about 3 mi (4.8 km) from the top of the Big Island of Hawaii's Chain of Craters Road, which follows a "chain" that also includes the Hiʻiaka, Puʻu Huluhulu, Kānenuiohamo, Makaopuhi and Nāpau craters.
This and the long delay between the eruption of the Chungará Andesites and the rest of the volcano's history may imply that the magmatic systems involved were different. [34] Magma output during the early stage was low, with a magma output of 0.13 cubic kilometres per year (0.031 cu mi/a) with the dome growth contributing 0.5 ± 0.18 cubic ...
The volcano was dormant for about half of last century, but rumbled back to life with a series of relatively small eruptions beginning in the 1990s. The government ordered evacuations then, and ...

The 1912 eruption was the largest eruption by volume in the 20th century, erupting a magma volume of about 13 cubic kilometers (3.1 cu mi). As many as 14 major earthquakes between M s {\displaystyle M_{\text{s}}} 6 to 7 , and over 100 earthquakes greater than M s {\displaystyle M_{\text{s}}} 5, resulted from the collapse of the caldera at Mount ...
