Huge tsunami hit Oman 1,000 years ago

Tue, 19/11/2019 - 16:55
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 that hit the coast of today's Sultanate of Oman about 1,000 years ago, as concluded by a recent study. The findings also show how urgently the region needs a well-functioning early warning system.

Fault-slip: AI to simulate tectonic plate deformation

Wed, 13/11/2019 - 23:03
Scientists have transformed the UNICORN computing code into an AI-like algorithm to more quickly simulate tectonic plate deformation due to a phenomenon called a ''fault slip,'' a sudden shift that occurs at the plate boundary. The team ran UNICORN at 416 petaflops and gained a 75-fold speedup from a previous state-of-the-art solver by fully leveraging the world's most powerful and smartest supercomputer, the IBM AC922 Summit.

Ground failure study shows deep landslides not reactivated by 2018 Anchorage Quake

Wed, 23/10/2019 - 20:03
Major landslides triggered by the 1964 magnitude 9.2 Great Alaska earthquake responded to, but were not reactivated by, the magnitude 7.1 Anchorage earthquake that took place 30 November 2018, researchers concluded in a new study.

What happens under the Yellowstone Volcano?

Thu, 17/10/2019 - 16:17
A recent study helps to better explain the processes in the Earth's interior beneath the Yellowstone supervolcano.

Rice irrigation worsened landslides in deadliest earthquake of 2018

Tue, 08/10/2019 - 15:46
Irrigation significantly exacerbated the earthquake-triggered landslides in Palu, on the Indonesian island of Sulawesi, in 2018, according to an international study.

Early warning signals heralded fatal collapse of Krakatau volcano

Tue, 01/10/2019 - 18:27
On 22 December 2018, a flank of the Anak Krakatau plunged into the Sunda strait between the Indonesian islands of Sumatra and Java, triggering a tsunami that killed 430 people. An international research team has now shown that the volcano produced clear warning signals before its collapse. The researchers recommend to use their study to improve monitoring of volcanoes.

Did long ago tsunamis lead to mysterious, tropical fungal outbreak in Pacific northwest?

Tue, 01/10/2019 - 13:39
The Great Alaskan Earthquake of 1964 and the tsunamis it spawned may have washed a tropical fungus ashore, leading to a subsequent outbreak of often-fatal infections among people in coastal regions of the Pacific Northwest, according to a new article.

'Treasure trove' of earthquake clues could be unearthed by wavy new technique

Tue, 24/09/2019 - 17:50
Geologists have improved upon methods to map seabed rocks, helping us better understand underwater earthquakes and the tsunamis they can cause.

Role of earthquake motions in triggering a 'surprise' tsunami

Thu, 05/09/2019 - 14:09
Geologists, geophysicists, and mathematicians show how coupled computer models can accurately recreate the conditions leading to the world's deadliest natural disasters of 2018, the Palu earthquake and tsunami, which struck western Sulawesi, Indonesia in September last year.

Earthquake study casts doubt on early warnings but hints at improved forecasting

Wed, 04/09/2019 - 18:06
A recent study investigated around 100,000 localized seismic events to search for patterns in the data. Scientists discovered that earthquakes of differing magnitudes have more in common than was previously thought. This suggests development of early warning systems may be more difficult than hoped. But conversely, similarities between some events indicate that predictable characteristics may aid researchers attempting to forecast seismic events.

Reconstructing Anak Krakatau flank collapse that caused Dec. 2018 Indonesian tsunami

Fri, 30/08/2019 - 20:07
A new study presents the detailed observation of a tsunami-generating volcano collapse by remote sensing. The study analyzes the 2018 collapse of Anak Krakatau, which triggered a tsunami that claimed over 430 lives and devastated coastal communities along the Sunda Strait, Indonesia.

Deducing the scale of tsunamis from the 'roundness' of deposited gravel

Sun, 25/08/2019 - 12:59
Scientists have found a link between the 'roundness' distribution of tsunami deposits and how far tsunamis reach inland. They sampled the 'roundness' of gravel from different tsunamis in Koyadori, Japan, and found a common, abrupt change in composition approximately 40% of the 'inundation distance' from the shoreline, regardless of tsunami magnitude. Estimates of ancient tsunami size from geological deposits may help inform effective disaster mitigation.

Researchers develop improved method for studying tsunami risk to bridges, buildings, roads

Wed, 14/08/2019 - 14:38
Researchers are paving the way toward greater safety for coastal residents and infrastructure by developing a better means of modeling the destructive force of tsunami waves.
