  • Volcanoes in the Hawaiian Islands arise from the Hawaii hotspot, and as the youngest volcano in the chain, Kamaʻehuakanaloa is the only Hawaiian volcano in the deep submarine preshield stage of development. (wikipedia.org)
  • Due to its high resolution the new Digital Terrain Model of the Stromboli Island gives interesting information about the submerged structure of the volcano, particularly about the volcano-tectonic and gravitational processes involving the submarine flanks of the edifice. (springeropen.com)
  • The thick crater walls of Pele's Pit - averaging 70 ft (20 m) in width, unusually thick for Hawaiian volcanic craters - suggest its craters have filled with lava multiple times in the past. (wikipedia.org)
  • The volcano is not monitored by ground-based instruments, but rather satellite imagery, distal geophysical data, and mariner reports through weekly reports of the Northern Mariana Islands Volcano Observatory posted by the U.S. Geological Survey, as well as the Washington Volcanic Ash Advisory Center (VAAC). (si.edu)
  • Several seismic units have been identified based on the geologic interpretation of Subbottom Chirp profiles recorded around the volcanic edifice and interpreted as volcanic acoustic basement pertaining to the volcano and overlying slide chaotic bodies emplaced during its complex volcano-tectonic evolution.

  • 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. (wikipedia.org)
  • From 1955 to 2021 the seamount was called "Lōʻihi", the Hawaiian word for "long", describing its shape. (wikipedia.org)
  • The chosen domain offers a unique opportunity for imaging material properties near an active subduction zone, due to the availability of well-recorded earthquakes in close proximity to the plate interface. (seismosoc.org)
  • Improved fits between data and synthetic waveforms motivate an ongoing large-scale inversion using 200 earthquakes recorded on as many as 100 broadband stations. (seismosoc.org)
  • The permanent seismic network of the National Institute of Geophysics and Oceanography (INGV, Italy) has been used, incremented for the experiment of 18 temporary stations and 18 Ocean Bottom Seismometers (OBS), deposited on the southeastern, southwestern and northeastern submerged flanks of the volcano after detailed morphobathymetric analysis (Di Fiore et al. (springeropen.com)
  • Until 1970, Kamaʻehuakanaloa was thought to be an inactive volcano that had been transported to its current location by sea-floor spreading. (wikipedia.org)
  • The Stromboli geophysical experiment has been already carried out based on onshore and offshore data acquisition in order to investigate the deep structure and the location of the magma chambers of the Stromboli volcano. (springeropen.com)
  • Kamaʻehuakanaloa's north-south trending rift zones form a distinctive elongated shape, from which the volcano's earlier Hawaiian name "Lōʻihi," meaning "long", derives. (wikipedia.org)
  • Kamaʻehuakanaloa's last known eruption was in 1996, before the earthquake swarm of that summer. (wikipedia.org)
  • 2001) of Etna changing from a hot-spot to a subduction type volcano and thus becoming more explosive There hasn't been any further research into this area to my knowledge - but certainly Etna has demonstrated that it has more explosive potential than was believed previously, both in the form of new eruptions - in particular, the very ash-rich 2002-2003 eruption - and in evidence coming from research on Etna's eruptive history.

  • Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire, Kamaʻehuakanaloa and the other volcanoes of the Hawaiian-Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary. (wikipedia.org)
  • So to my knowledge that's the currently preferred hypothesis concerning the question why Etna is there, and so Etna would actually be a type of volcano unlike all others, which certainly fits with its extremely complicated and versatile dynamics. (scienceblogs.com)
  • Kamaʻehuakanaloa Seamount (previously known as Lōʻihi) is an active submarine volcano about 22 mi (35 km) off the southeast coast of the island of Hawaii. (wikipedia.org)
  • So it can be said, the convergence occurs at two different speeds, and the two domains are separated by a major system of tectonic structures, which are also seismically active (producing, among others, the major earthquakes of 1693 in southeast Sicily and 1908 in the Messina strait area). (scienceblogs.com)
  • Until 1970, Kamaʻehuakanaloa was thought to be an inactive volcano that had been transported to its current location by sea-floor spreading. (wikipedia.org)
  • Is this verified, and does that mean that the three 'historic' volcanoes (Vesuvius, Campi Flegrei and Ischia) are now thought of as semi-independent centers in a single volcanic system? (scienceblogs.com)
  • The volcano has remained relatively active since the 1996 swarm and is monitored by the United States Geological Survey (USGS). (wikipedia.org)
  • When scientists investigated a series of earthquakes off Hawaii in 1970, they discovered that Kamaʻehuakanaloa was an active member of the Hawaiian-Emperor seamount chain. (wikipedia.org)
