This study reports the result of deep ocean-bottom seismometer recording of an undersea volcanic event in progress. An array of five three-component, isolated sensor ocean-bottom seismometers (ISOBS) was deployed for 28 days on the summit and flanks of Loihi Seamount, Hawaii, to monitor seismicity. The deployment was prompted by reports from the Hawaiian Volcano Observatory (HVO) of a swarm of small-magnitude events located beneath the active submarine volcano in late September, 1986… 

Seismicity and Velocity Structure of Lō'ihi Submarine Volcano and Southeastern Hawai'i

Hundreds of earthquakes were recorded during a nine‐month ocean bottom seismometer deployment surrounding Lō'ihi submarine volcano, Hawai'i. The 12‐station ocean bottom seismometer network widened

Seismicity and Velocity Structure of Loihi Seamount from the 1996 Earthquake Swarm

The largest earthquake swarm yet recorded on Loihi submarine volcano took place in July and August of 1996. The swarm consisted of two phases of seismic activity and was associated with the formation

Seismic and acoustic signals detected at Lo'ihi Seamount by the Hawai'i Undersea Geo‐Observatory

The Hawai'i Undersea Geo‐Observatory (HUGO) is an ocean bottom observatory located on the summit of Lo'ihi seamount, Hawai'i. An electro‐optical cable connects the HUGO junction box to a shore

Evolution of the lithosphere of the Hawaiian-Emperor seamount chain, Pacific Ocean, as inferred from geophysical data

The analysis of geological and geophysical data on the Hawaiian-Emperor seamount chain indicates that the commonly assumed origin of its lithosphere is inconsistent with the geothermal model of the

Petrology and geochronology of basalt breccia from the 1996 earthquake swarm of Loihi seamount, Hawaii: magmatic history of its 1996 eruption

Abstract Samples of basalt were collected during the Rapid Response cruise to Loihi seamount from a breccia that was probably created by the July to August 1996 Loihi earthquake swarm, the largest

Structure of Lō‘ihi Seamount, Hawai‘i and Lava Flow Morphology From High-Resolution Mapping

High-resolution bathymetric data were collected using AUV Sentry at the summit and at two hydrothermal vent fields on the deep south rift of L¯o‘ihi Seamount. The summit map records a nested series

Seamounts – characteristics, formation, mineral deposits and biodiversity

Seamounts represent crust-mantle activities and are areas of petrological deviations, biodiversity, seismicity and hydrothermal events. An estimated ~50 million tons/year of basalts are required to

Pathological Seismology: An Investigation of Seismic Signals in the Monterey Bay

Well-coupled ocean bottom seismometers (OBSs) developed at MBARI have been successfully deployed in Monterey Canyon, collecting over six weeks of data in 1996 and almost three months of data in 1997.
