where do most of kilauea's eruptions occur
Kīlauea The first well-documented eruption of Kīlauea occurred in 1823 (Western contact and written history began in 1778). Since then, the volcano has erupted repeatedly. Most historical eruptions occurred at the volcano's summit or its eastern rift zone, and were prolonged and effusive in character. The geological record shows, however, that violent explosive activity predating European contact was extremely common; in 1790 one such eruption killed more than 400 people, making it the deadliest volcanic eruption in what is now the United States.[5] Should explosive activity start anew, the volcano would become much more of a danger to humans. Kīlauea's current eruption dates back to January 3, 1983, and is by far its longest-duration historical period of activity, as well as one of the longest-duration eruptions in the world; as of January 2011, the eruption has produced 3.5 km3 (1 cu mi) of lava and resurfaced 123.2 km2 (48 sq mi) of land.
Types of volcanic eruptions Magmatic eruptions produce juvenile clasts during explosive decompression from gas release. They range in intensity from the relatively small lava fountains on Hawaii to catastrophic Ultra-Plinian eruption columns more than 30 km (19 mi) high, bigger than the eruption of Mount Vesuvius in 79 that buried Pompeii.[1]
