Global seismographic networks (GSNs) emerged during the late nineteenth and early
twentieth centuries, facilitated by seminal international developments in theory, technology …

Acoustics play a central role in humankind's interactions with the ocean and the life within.
Passive listening to ocean “soundscapes” informs us about the physical and bio-acoustic …

Seafloor geophysical instrumentation is challenging to deploy and maintain but critical for
studying submarine earthquakes and Earth's interior. Emerging fiber-optic sensing …

Tsunami warning centres face the challenging task of rapidly forecasting tsunami threat
immediately after an earthquake, when there is high uncertainty due to data deficiency. Here …

Observation of polarization modulation at the output of a submarine link, extracted from a
standard coherent telecom receiver, can be used to monitor geophysical events such as sea …

Marine geohazards related to geological features and processes in coastal and offshore
environments can cause damage to health, environment, field installations, or loss of life and …

We introduce GUARDIAN, a near-real-time (NRT) ionospheric monitoring software for
natural hazards warning. GUARDIAN's ultimate goal is to use NRT total electronic content …

Many of the world's volcanoes are hidden beneath the ocean's surface where eruptions are
difficult to observe. However, seismo‐acoustic signals produced by these eruptions provide …

This paper reviews achievements and findings from studies associated with numerical
modeling of tsunami since the 2011 Tohoku earthquake, and addresses challenges for …

Deep-sea ecosystems are reservoirs of biodiversity that are largely unexplored, but their
exploration and biodiscovery are becoming a reality thanks to biotechnological advances …
