Let us see some negative effects of volcanoes: Eruptions occurring close to human settlements may spill and destroy lives and property. People often have to be evacuated. Example: Chaparrastique volcano in El Salvador started erupting on 29 Dec 2013. Anyone living within 2 miles of the volcano ...
Although this mountain in central El Salvador, just a few miles east of the capital city San Salvador, has experienced only two eruptions in its history, the first known eruption, in roughly A.D. 431, was a doozy. It blanketed much of central and western El Salvador with pumice and ...

11-01-24 About 250 million years about 95 per cent of life was wiped out in the sea and 70 per cent on land. Researchers at the University of Calgary believe they have discovered evidence to support massive volcanic eruptions burnt significant volumes of coa... 精确找到火山喷发的位置可能...
The Central America Volcanic Arc includes hundreds of volcanic formations, ranging from major , to and . Some of these have produced large explosive eruptions, like the colossal eruption of the in 1902. Central America's highest volcanoes are found in Guatemala and include the and , both above...
The current Conchagua Volcano consists of two cones, Ocotal and Banderas, built by repeated Strombolian eruptions associated with effusions of basaltic lavas. The uppermost unit consists of a white tuff preserved in the sedimentary fill of several tectonic valleys west of Conchagua. The white tuff ...
Here is information on significant earthquakes and volcanic eruptions going back as early as A.D. 79 and through the present. A.D. 79 Aug. 24, Italy: eruption of Mt. Vesuvius buried cities of Pompeii and Herculaneum, killing thousands. 856 Dec. 22, Damgh
Icelandic observers believe that volcanic activity in the region will continue since large amounts of lava have formed underneath the ground. Among the countries which have seen eruptions this year, the Smithsonian Institution's Global Volcanism Program lists Mexico, El Salvador, the Philippines, ...
For example, there are numerous places where ascent rates for explosive eruptions are low (e.g., associated with small Vulcanian eruptions at Chaparrastique, El Salvador and Colima, Mexico) and effusive ascent rates are high (e.g., rapid dome growth at Chaiten, Chile, following initial ...
(b) Percentage of eruptions dated using 14C from 2.5-70 ka, calculated in 2,500 year bins. The peak at 56 ka is the Congo (CGT) eruption from Coatepeque Caldera (El Salvador), constrained using high sensitivity 14C analysis; see Rose et al. (1999) for details. For (a) and (b) ...
