Sea cave preserves 5,000-year snapshot of tsunamis

Wed, 19/07/2017 - 13:48
Scientists digging in a sea cave in Indonesia have discovered the world's most pristine record of tsunamis, a 5,000-year-old sedimentary snapshot that reveals for the first time how little is known about when earthquakes trigger massive waves.

Forgotten archives reveal street-level impact of 1918 Puerto Rico earthquake and tsunami

Wed, 05/07/2017 - 18:29
Repair petitions filed in the wake of the 1918 Puerto Rico earthquake and tsunami, stored and forgotten in the San Juan archives for nearly 100 years, are giving scientists a house-by-house look at the damage wrought by the magnitude 7.3 event.

Distant earthquakes can cause underwater landslides

Tue, 27/06/2017 - 18:44
New research finds large earthquakes can trigger underwater landslides thousands of miles away, weeks or months after the quake occurs.

Japanese slow earthquakes could shed light on tsunami generation

Thu, 15/06/2017 - 19:27
Understanding slow-slip earthquakes in subduction zone areas may help researchers understand large earthquakes and the creation of tsunamis, according to researchers who used data from instruments placed on the seafloor and in boreholes east of the Japanese coast.

New evidence reveals source of 1586 Sanriku, Japan tsunami

Tue, 06/06/2017 - 22:03
A team of researchers re-examined historical evidence around the Pacific and discovered the origin of the tsunami that hit Sanriku, Japan in 1586 -- a mega-earthquake from the Aleutian Islands that broadly impacted the north Pacific. Until now, this was considered an orphan tsunami, a historical tsunami without an obvious local earthquake source, likely originating far away.

Why the Sumatra earthquake was so severe

Thu, 25/05/2017 - 19:15
An international team of scientists has found evidence suggesting the dehydration of minerals deep below the ocean floor influenced the severity of the Sumatra earthquake, which took place on Dec. 26, 2004.

From where will the next big earthquake hit the city of Istanbul?

Tue, 16/05/2017 - 15:47
Scientists reckon with an earthquake with a magnitude of 7 or greater in this region in the coming years. The extent of such seismic threat to this Turkish city of Istanbul actually depends on how strongly the tectonic plates are entangled and on the exact nucleation point of the earthquake. A team of researchers now presents a study indicating that the next major earthquake is more likely to originate in Istanbul's eastern Marmara Sea.

Natural disasters pose grave threat to planet's last Javan rhinos

Wed, 10/05/2017 - 16:53
The world's only population of Javan rhinoceros, already under severe threat from poaching, could go extinct in the future due to natural disasters, including volcanic eruptions and tsunamis.

Earthquakes can make thrust faults open violently and snap shut

Mon, 01/05/2017 - 18:16
Engineers and scientists experimentally observe surface twisting in thrust faults that can momentarily rip open the earth's surface.

Tsunami formation: Study challenges long-held theory

Wed, 26/04/2017 - 21:47
A new study is challenging a long-held theory that tsunamis form and acquire their energy mostly from vertical movement of the seafloor.

New model could help predict major earthquakes

Wed, 26/04/2017 - 14:23
Researchers have characterized several earthquakes that struck South America's west coast over the last 100 years by using seismographic data, tsunami recordings, and models of the rapid plate movements associated with these natural disasters. The team showed that some earthquakes were linked to the same sites of rupture at plate boundaries and others to different sites. Thus, they revealed the periodicity and intensity of earthquakes associated with particular sites, potentially aiding future earthquake prediction.

New study ranks hazardous asteroid effects from least to most destructive

Wed, 19/04/2017 - 17:20
If an asteroid struck Earth, which of its effects -- scorching heat, flying debris, towering tsunamis -- would claim the most lives? A new study has the answer: violent winds and shock waves are the most dangerous effects produced by Earth-impacting asteroids.

Communicating tsunami evacuations effectively

Tue, 18/04/2017 - 16:52
An effective communication approach incorporating computer simulations could help people find practical means to evacuate in the event of a tsunami.

Developing a microinsurance plan for California earthquakes

Wed, 12/04/2017 - 16:57
Nine out of 10 Californians are uninsured against earthquake risk, which could slow economic recovery in neighborhoods and cities around the state after a damaging quake. On-demand or use-based small insurance policies -- sometimes called microinsurance -- could help fill in that financial gap.

Seismologists offer detailed look at New Zealand's Kaikoura earthquake

Wed, 12/04/2017 - 16:11
The magnitude 7.8 Kaikoura earthquake that struck the South Island of New Zealand last November was the largest on-land recorded earthquake in the country's history.

Performance of earthquake early warning systems

Tue, 11/04/2017 - 18:07
The future of earthquake early warning systems may be contained in smartphones -- and vehicles, and 'smart' appliances and the increasing number of everyday objects embedded with sensors and communication chips that connect them with a global network.

Could a Colorado earthquake have been triggered by dinosaur extinction impact?

Tue, 11/04/2017 - 18:07
Researchers have found signs of fault displacement at well-known rock outcrops in Colorado that mark the end-Cretaceous asteroid impact that may have hurried the extinction of the dinosaurs.

What happens to the boats? The 1755 Lisbon earthquake and Portuguese tsunami literacy

Mon, 10/04/2017 - 21:19
Authors of a new report point out the need for continued geoscience education on the topic of tsunamis and other earthquake-related hazards.
