Eruption of South Sarigan Seamount, Northern Mariana Islands: Insights into Hazards from Submarine Volcanic Eruptions [PDF]
Oceanography, 2014 The eruption of South Sarigan Seamount in the southern Mariana arc in May 2010 is a reminder of how little we know about the hazards associated with submarine explosive eruptions or how to predict these types of eruptions. Monitored by local seismometers

Geohazards in the Western Ionian Sea: Insights from Non-Earthquake Signals Recorded by the NEMO-SN1 Seafloor Observatory [PDF]
Oceanography, 2014 Seafloor instability resulting from both tectonics and volcanism affects the Western Ionian Sea. The NEutrino Mediterranean Observatory-Submarine Network 1 (NEMO-SN1), deployed 25 km offshore eastern Sicily at 2,100 m water depth, records a variety of ...

Sea-floor tectonics and submarine hydrothermal systems [PDF]
, 2005 The discovery of metal-depositing hot springs on the sea floor, and especially their link to chemosynthetic life, was among the most compelling and significant scientific advances of the twentieth century. More than 300 sites of hydrothermal activity and

Glass in the submarine section of the HSDP2 drill core, Hilo, Hawaii [PDF]
, 2004 The Hawaii Scientific Drilling Project recovered ~3 km of basalt by coring into the flank of Mauna Kea volcano at Hilo, Hawaii. Rocks recovered from deeper than ~1 km were deposited below sea level and contain considerable fresh glass. We report electron

Hydroacoustics detect submarine volcanism
Eos, Transactions American Geophysical Union, 1993 On January 19, an unusual clustering of impulsive hydroacoustic signals (T‐phases) was observed on recordings from SOFAR (Sound Fixing and Ranging) channel hydrophones located near the island of Oahu, Hawaii. Accompanying these randomly distributed T‐phases was a continuously elevated level of background noise. The most intense activity began around 10

Origen del Alineamiento Submarino de Pascua: morfología y lineamientos estructurales [PDF]
, 2014 Indexación: Web of Science; Scielo.ABSTRACT. The Easter submarine alignment corresponds to a sequence of seamounts and oceanic islands which runs from the Ahu-Umu volcanic fields in the west to its intersection with the Nazca Ridge in the east, with a ...

Models of Hawaiian volcano growth and plume structure: Implications of results from the Hawaii Scientific Drilling Project [PDF]
, 1996 The shapes of typical Hawaiian volcanoes are simply parameterized, and a relationship is derived for the dependence of lava accumulation rates on volcano volume and volumetric growth rate.

Submarine volcanoes along the Aegean volcanic arc
Tectonophysics, 2013 Abstract The Aegean volcanic arc has been investigated along its offshore areas and several submarine volcanic outcrops have been discovered in the last 25 years of research. The basic data including swath bathymetric maps, air-gun profiles, underwater photos and samples analysis have been presented along the four main volcanic groups of the arc. The
