The lava flow hazard zones are based on location of eruptive vents, past lava coverage, and topography. [3] Zone 1 - Includes summits and rift zones of Kilauea and Mauna Loa volcanoes, where vents have been repeatedly active in historical time. Zone 2 - Areas adjacent to and downslope of zone 1. 15-25% of zone 2 has been covered by lava since ...
Description Hawaii Volcanoes Hazard Map.svg. English: The Island of Hawaiʻi was mapped into 9 lava flow hazard zones meant to portray the future long-term hazard due to lava flow activity.

Before Koʻolau volcano was active, between 3.5 and 2.74 million years ago, Waiʻanae volcano formed the western part of Oʻahu. [71] Koʻolau volcano appears to be unrelated to the Honolulu Volcanics, [6] which are considered to be a separate volcanic system; [58] sometimes the "Kokohead Volcanics" are split off from the Honolulu Volcanics.

The Hawaiian Volcano Observatory (HVO) is an agency of the U.S. 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, and Haleakalā ...
The Hawaiʻi hotspot is a volcanic hotspot located near the namesake Hawaiian Islands, in the northern Pacific Ocean.One of the best known and intensively studied hotspots in the world, [1] [2] the Hawaii plume is responsible for the creation of the Hawaiian–Emperor seamount chain, a 6,200-kilometer (3,900 mi) mostly undersea volcanic mountain range.
For example, the summits and rift zones of Kilauea and Mauna Loa volcanoes are rated Hazard Zone 1. [8] Using this same scale, preliminary estimates of lava-flow hazard zones on Maui made in 1983 by the U.S. Geological Survey rated the summit and southwest rift zone of Haleakala as
Volcano: Kīlauea's Lower East rift zone: Start date: May 3, 2018 (): End date: September 4, 2018 (): Type: Fissure eruption: Location: Hawaii Island, Hawaii, United States: Impact: 24 injuries; lava fountains, lava flows; at least $800 million (2018 USD) in property damage; volcanic gas and earthquakes forced the evacuation of populated areas and destroyed houses, roads, and utilities.
August 23, 2024 at 4:30 PM. Crack in Chain of Craters Road. Hawaii's Mt. Kīlauea is not erupting, but increasing seismic activity near the volcano has created massive cracks along a road inside ...
