Magmas erupted in deep-water environments (> 500 m) are subject to physical constraints
very different to those for subaerial eruptions, including hydrostatic pressure, bulk modulus …

Volcanic eruptions are common, with more than 50 volcanic eruptions in the United States
alone in the past 31 years. These eruptions can have devastating economic and social …

Deep-sea submarine eruptions are the least known type of volcanic activity, due to the
difficulty of detecting, monitoring, and sampling them. Following an intense seismic crisis in …

Seismic observations in volcanically active calderas are challenging. A new cabled
observatory atop Axial Seamount on the Juan de Fuca ridge allows unprecedented real-time …

Deformation of the ground surface at active volcanoes provides information about magma
movements at depth. Improved seafloor deformation measurements between 2011 and …

Since 2018, the submarine east flank of Mayotte Island (Comoros archipelago) is the site of
a major eruption located at 3.5 km depth bsl on a WNW-ESE volcanic ridge. Samples …

The architecture of magma plumbing systems plays a fundamental role in volcano eruption
and evolution. However, the precise configuration of crustal magma reservoirs and conduits …

The Ocean Observatories Initiative (OOI) is an integrated suite of instrumented platforms and
discrete instruments that measure physical, chemical, geological, and biological properties …

Axial Seamount, an extensively instrumented submarine volcano, lies at the intersection of
the Cobb–Eickelberg hot spot and the Juan de Fuca ridge. Since late 2014, the Ocean …

The unique ecosystems and biodiversity associated with mid-ocean ridge (MOR)
hydrothermal vent systems contrast sharply with surrounding deep-sea habitats, however …
