The Cascade volcanoes have had more than 100 eruptions over the past few thousand years, many of them explosive eruptions. [21] However, certain Cascade volcanoes can be dormant for hundreds or thousands of years between eruptions, and therefore the great risk caused by volcanic activity in the regions is not always readily apparent.
This is a list of Cascade volcanoes, i.e. volcanoes formed as a result of subduction along the Cascadia subduction zone in the Pacific Northwest of North America. The volcanoes are listed from north to south, by province or state: British Columbia , Washington , Oregon , and California .
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 country has been shaken by more than 800 small earthquakes today alone, prompting fears that the tremors could disrupt the Fagradalsfjall volcano on the Reykjanes peninsula in the southwest of ...
Campi Flegrei, a large dormant volcano near Naples, has a history of eruptions, and the last one was in 1538. Recently, increased seismic activity and rising land levels have raised concerns among ...
There are other volcanoes in the northern Cascades region that have not been assessed one of these risk levels which warrant monitoring. Volcanoes that have not erupted during the Holocene period were not included. USGS has noted, though less probable, that it is still possible for volcanoes to erupt on longer intervals than mentioned. [6]
The Cascade Volcanoes are an active volcanic region along the western side of the Pacific Northwest. The Columbia Plateau is a region of subdued geography that is inland of the Cascade Volcanoes, and the North Cascades are a mountainous region in the northwest corner of the United States, extending into British Columbia.
Iceland is highly susceptible to natural disasters because it lies on the Mid-Atlantic Ridge – a divergent plate boundary where the North American Plate and the Eurasian Plate are moving away ...
