First prepared in 1974 by Donal Mullineaux and Donald Peterson of the USGS and revised in 1992 for the Island of Hawaiʻi, [1] the maps outline the qualitative hazard posed by lava flows based on the history of lava flow activity on each of the five volcanoes that form the Island of Hawaiʻi and Haleakalā volcano on the island of Maui. Zone 1 ...
The Hawaiian Volcano Observatory (HVO) is an agency of the United States Geological Survey (USGS) and one of five volcano observatories operating under the USGS Volcano Hazards Program. Based in Hilo, Hawaii , the observatory monitors six Hawaiian volcanoes: Kīlauea , Mauna Loa , Kamaʻehuakanaloa (formerly Lōʻihi), Hualālai , Mauna Kea ...
Like other Hawaiian volcanoes Koʻolau is a shield volcano that grew through lava flows erupted from a rift system with a central caldera, although a large section of the volcano has sunk below sea level. This volcano constitutes the tholeiitic stage of Hawaiian volcanism, [70] and developed possibly during Miocene to Pleistocene time. [41]
View from the top of Diamond Head, 2015. Diamond Head is a volcanic tuff cone on the Hawaiian island of Oʻahu.It is known to Hawaiians as Lēʻahi (pronounced [leːˈʔɐhi]), which is most likely derived from lae (browridge, promontory) plus ʻahi (tuna) because the shape of the ridgeline resembles the shape of a tuna's dorsal fin.

The Hawaiian–Emperor seamount chain is a series of volcanoes and seamounts extending about 6,200 km (3,900 mi) across the Pacific Ocean. [ n 1 ] The chain was produced by the movement of the ocean crust over the Hawaiʻi hotspot , an upwelling of hot rock from the Earth's mantle .
Like all Hawaiian volcanoes, Kīlauea was formed as the Pacific tectonic plate moved over the Hawaiian hotspot in the Earth's underlying mantle. [12] Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has produced the 6,000 km (3,700 mi)-long Hawaiian–Emperor seamount chain. [13]
One of the world's most active volcanoes began erupting early Monday morning, with glowing lava flows bursting within one of its craters, according to the U.S. Geological Survey. Hawaii's Kilauea ...
Hawaiʻi Volcanoes National Park is a national park of the United States located in Hawaii on the island of Hawaii. The park encompasses two active volcanoes: Kīlauea , one of the world's most active volcanoes, and Mauna Loa , the world's largest shield volcano.
