Tsunamis’ magnetic fields are detectable before sea level change

A new study finds the magnetic field generated by a tsunami can be detected a few minutes earlier than changes in sea level and...

Earthquake depth impacts potential tsunami threat

Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local...

Researchers identify new source for earthquakes and tsunamis in the Greater...

Researchers have discovered geologic evidence that unusually large earthquakes and tsunamis from the Tokyo region -- located near tectonic plate boundaries that are recognized...

Previously unrecognized tsunami hazard identified in coastal cities

A new study found overlooked tsunami hazards related to undersea, near-shore strike-slip faults, especially for coastal cities adjacent to faults that traverse inland bays....

Earthquake, tsunami hazards from subduction zones might be higher than current...

Two of the most destructive forces of nature -- earthquakes and tsunamis -- might actually be more of a threat than current estimates according...

Fujitsu leverages world’s fastest supercomputer and AI to predict tsunami flooding

A new AI model that harnesses the power of the world's fastest supercomputer, Fugaku, can rapidly predict tsunami flooding in coastal areas before the...

Deep, slow-slip action may direct largest earthquakes and their tsunamis

Megathrust earthquakes and subsequent tsunamis that originate in subduction zones like Cascadia -- Vancouver Island, Canada, to northern California -- are some of the...

How water in the deep Earth triggers earthquakes and tsunamis

In a new study, published in the journal Nature, an international team of scientists provide the first conclusive evidence directly linking deep Earth's water...

New tsunami risk identified in Indonesia

A team of scientists led by Heriot-Watt University has identified a potential new tsunami risk in Indonesia by mapping below the seabed of the...

Shifts in deep geologic structure may have magnified great 2011 Japan...

On March 11, 2011, a magnitude 9 earthquake struck under the seabed off Japan -- the most powerful quake to hit the country in...

Source of Indonesian earthquakes and tsunamis located

Devastating historical earthquakes and tsunamis in Indonesia can be traced to a recently discovered submarine extensional fault system, where sediment slumping along the fault...

Tsunami unleashed by Anak Krakatoa eruption was at least 100m high

The deadly volcanic eruption of Anak Krakatoa in 2018 unleashed a wave at least 100m high that could have caused widespread devastation had it...

New technology developed to improve forecasting of Earthquakes, Tsunamis

University of South Florida geoscientists have successfully developed and tested a new high-tech shallow water buoy that can detect the small movements and changes...

Oman tsunami : Huge tsunami hit Oman 1,000 years ago

15-meter high waves that pushed boulders the weight of a Leopard tank inland: This is more or less how one can imagine the tsunami...

Role of earthquake motions in triggering a ‘surprise’ tsunami

In newly published research, an international team of geologists, geophysicists, and mathematicians show how coupled computer models can accurately recreate the conditions leading to...

Ancient Tsunamis: Deducing the scale of tsunamis from the ’roundness’ of...

Scientists from Tokyo Metropolitan University and Ritsumeikan University have found a link between the "roundness" distribution of tsunami deposits and how far tsunamis reach...

Tsunami signals to measure glacier calving in Greenland

In recent years, glaciers near the North and South poles, as well as in mountainous areas, have been shrinking due to the effect of...
