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.
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 ...
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.
Kīlauea is the second-youngest product of the Hawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain. Because it lacks topographic prominence and its activities historically coincided with those of Mauna Loa , Kīlauea was once thought to be a satellite of its much larger neighbor.
The name Kamaʻehuakanaloa is a Hawaiian language word for "glowing child of Kanaloa", the god of the ocean. [10] This name was found in two Hawaiian mele from the 19th and early twentieth centuries based on research at the Bishop Museum and was assigned by the Hawaiʻi Board on Geographic Names in 2021 and adopted by the U.S. Geological Survey.
The second-largest volcano in Hawaii had been lying dormant for the last two months after bursting open in January and June this year. “The opening phases of eruptions are dynamic,” said USGS ...
In geology, hotspots (or hot spots) are volcanic locales thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. [1] Examples include the Hawaii , Iceland , and Yellowstone hotspots .
The Emperor and Hawaiian chains are separated by a large L-shaped bend that causes the orientations of the chains to differ by about 60 degrees. This bend was long attributed to a relatively sudden change in the direction of plate motion, but research conducted in 2003 suggests that it was the movement of the hotspot itself that caused the bend ...
