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.

Future tsunamis possible in the Red Sea's Gulf of Elat-Aqaba

Wed, 12/06/2019 - 19:14
Researchers who took a closer look at a 1995 tsunami in the Gulf of Elat-Aqaba, at the northeastern tip of the Red Sea, say that the gulf's surrounding countries should prepare for future tsunami hazards in the economically developing vital region.

How tides can trigger earthquakes

Fri, 07/06/2019 - 14:10
Some earthquakes along mid-ocean ridges are linked with low tides, but nobody could figure out why. In a new study, researchers have uncovered the mechanism for this seeming paradox, and it comes down to the magma below the mid-ocean ridges.

Scientists find telling early moment that indicates a coming megaquake

Wed, 29/05/2019 - 19:51
Scientists combing through databases of earthquakes since the early 1990s have discovered a possible defining moment 10-15 seconds into an event that could signal a magnitude 7 or larger megaquake.
