The volcanic rocks of the Honolulu Volcanics are diverse; they include alkali basalts, melilite and nepheline basalts, basanites, [3] melilite, [63] nephelinite [85] and websterite, [63] and form an alkaline [81]-nephelinite suite. [2] The variations in composition reflect distinct proportions of melts produced from parent rocks. [86]
The crater was formed some 75,000 to 100,000 years ago during the secondary activity of the Honolulu Volcanic Series.A crater resulted from the ejection of hot lava through cracks in the old coral reefs which, at the time, extended to the foot of the Koʻolau Mountain Range.
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]

This timeline of volcanism on Earth includes a list of major volcanic eruptions of approximately at least magnitude 6 on the Volcanic explosivity index (VEI) or equivalent sulfur dioxide emission during the Quaternary period (from 2.58 Mya to the present). Other volcanic eruptions are also listed.
A magnitude 5.7 earthquake struck the world’s largest active volcano on Friday — Mauna Loa on the Big Island of Hawaii — knocking items off shelves and cutting power in a nearby town but not ...

Halemaʻumaʻu (six syllables: HAH-leh-MAH-oo-MAH-oo) is a pit crater within the much larger Kīlauea Caldera at the summit of Kīlauea volcano on island of Hawaiʻi. The roughly circular crater was 770 meters (2,530 ft) x 900 m (2,950 ft) before collapses that roughly doubled the size of the crater after May 3, 2018. [ 1 ]
