Prediction of volcanic activity, and volcanic eruption forecasting, is an interdisciplinary monitoring and research effort to predict the time and severity of a volcano's eruption. Of particular importance is the prediction of hazardous eruptions that could lead to catastrophic loss of life, property, and disruption of human activities.
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. Some dangerous volcanoes in "populated areas" appear many times: Santorini six times, and Yellowstone hotspot 21 times.
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] A larger eruption occurred on 7 November. [77] On 8 November, the volcano erupted several times, one bearing an ash plume with a height reaching 10 km (6.2 mi ...

Many geological features in Western United States have a Northeastern orientation, the North American craton motion has the same orientation as well. [1] For example: the Trans-Challis fault zone, Idaho; the Snake River in Oregon; the Garlock Fault, California; the Colorado River in Utah; the Colorado Mineral Belt; Crater Flat-Reveille Range-Lunar Crater lineament, the Northwestern Nevada ...
The island had three volcanoes. Perboewatan (410 ft) and Danan (1,480 ft) were destroyed during the eruption, and Rakata (2,667 ft) was half destroyed and the surviving half remains above sea level. In 1928, a new volcano called Anak Krakatoa (1,063 ft) grew above sea level, forming a new island by Rakata's island. 4 Volcán de Fuego [25] Guatemala

The old volcano is exposed in the walls of an old 3.5 km × 4.5 km (2.2 mi × 2.8 mi) wide caldera, referred to as Tayawan Caldera by Delfin. Some of the nearby peaks are the remnants of ancestral Pinatubo, left behind when the softer parts of the old mountain slopes were eroded by weathering .
