Sixty-six million years ago a miles-wide asteroid struck Earth, wiping out nearly all the dinosaurs and around three-quarters of the planet’s plant and animal species….
Scientists explain an unusual tsunami. A new study published in the journal Nature describes the process that produced and propagated an unusual tsunami following the catastrophic…
UM Rosenstiel School scientist Sam Purkis discovered evidence of a 500-year-old landslide, and a sizable tsunami, that could have implications for coastline development of coastlines…
Researchers uncover why a complex earthquake in the south Atlantic sent an unexpected tsunami around the world in 2021. A 47 km-deep, magnitude 7.5 earthquake…
The Hunga-Tonga-Hunga-Ha’apai volcano near Tonga in the South Pacific erupted with such force on January 15, 2022, that it is thought to be the biggest…
The dramatic collapse of Indonesia’s Anak Krakatau volcano in December 2018 resulted from long-term destabilizing processes, and was not triggered by any distinct changes in…
Magnetic field information could provide earlier disaster warning to at-risk regions, potentially saving lives. A new study finds the magnetic field generated by a tsunami…
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 tsunamis….
This threatens with sudden destruction of coastal cities and numerous human casualties. An international team of scientists from 20 countries identified 47 problems that hinder…
Two of the most destructive forces of nature — earthquakes and tsunamis — might actually be more of a threat than current estimates according to…
On March 11, 2011, a magnitude 9.1 earthquake jolted the seafloor about 70 kilometers (45 miles) offshore of Japan’s Tohoku region. It was the largest…
Megathrust earthquakes and subsequent tsunamis that originate in subduction zones like Cascadia — Vancouver Island, Canada, to northern California — are some of the most…
When he first encountered Lituya Bay in 1786, the French explorer Jean-François de Galaup La Pérouse was intrigued by an odd line in the forests…
Using NASA satellite imagery and software processing approaches, a group of geoscientists has discovered a landslide-generated tsunami threat in Barry Arm, Alaska, that will likely…
While kayaking in Barry Arm fjord in June 2019, Valisa Higman, an artist-in-residence at Alaska’s Chugach National Forest, noticed some odd fractures on a cliff…
Careful engineering of low, plant-covered hills along shorelines can mitigate tsunami risks with less disruption of coastal life and lower costs compared to seawalls. In…
Where tectonic plates meet, a change in angle. On March 11, 2011, a magnitude 9 earthquake struck under the seabed off Japan–the most powerful quake…
Deducing the scale of tsunamis from the ’roundness’ of deposited gravel. Scientists from Tokyo Metropolitan University and Ritsumeikan University have found a link between the…
