The 2018 lower Puna eruption was a volcanic event on the island of Hawaiʻi, on Kīlauea volcano's East Rift Zone that began on May 3, 2018. It is related to the larger eruption of Kīlauea that began on January 3, 1983, though some volcanologists and USGS scientists have discussed whether to classify it as a new eruption. [2]
On the evening of January 29, 1997, a series of earthquakes struck Kīlauea's east rift zone. Deep within the rift zone, magma was escaping from the conduit leading to the Puʻu ʻŌʻō vent, cutting off the supply to the ongoing eruption. The lava pond at Puʻu ʻŌʻō drained, and residents 10 miles (16 km) away heard a low, rumbling roar ...
These eruptions have taken place from pit craters and the main caldera, as well as parasitic cones and fissures along the East and Southwest rift zones. They are generally fluid ( VEI -0) Hawaiian eruptions , but more violent eruptions have occurred throughout Kīlauea's eruptive history, with the largest recorded explosive eruption having ...
According to the Hawaiian Volcano Observatory, the eruption started within the middle East Rift Zone and moved into the Napau Crater. It originally began on Sunday at the zone, then stopped after ...
Kilauea erupted most recently between Sept. 15-20 along the middle East Rift Zone, ... marking the first eruption in that region of the volcano in about 50 years. The last one took place in ...
The eastern rift zone is a dominant feature on the volcano; it is almost entirely covered in lava from the last 400 years, and at its crest near the summit is 2 to 4 km (1 to 2 mi) wide. [26] Non-localized eruptions, typical of rift zone activity, [22] have produced a series of low-lying ridges down the majority of the east rift zone's length. [26]
“Things changed radically in 2018 when the East Rift Zone vent, called Puʻu ʻŌʻō, collapsed. It robbed all of the magma that was up here at the summit of Kilauea and the summit collapsed ...
A map of East Africa showing some of the historically active volcanoes (as red triangles) and the Afar Triangle (shaded at the center), which is a so-called triple junction (or triple point) where three plates are pulling away from one another: the Arabian plate and two parts of the African plate—the Nubian and Somali—splitting along the East African Rift Zone Main rift faults, plates ...
