  • Japanese slow earthquakes could shed light on tsunami generation
    on June 15, 2017 at 6:27 pm

    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
    on June 6, 2017 at 9:03 pm

    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
    on May 25, 2017 at 6:15 pm

    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?
    on May 16, 2017 at 2:47 pm

    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. […]

  • New model could help predict major earthquakes
    on April 26, 2017 at 1:23 pm

    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. […]

  • Hazardous asteroid effects ranked from least to most destructive
    on April 19, 2017 at 4:20 pm

    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. […]

  • Developing a microinsurance plan for California earthquakes
    on April 12, 2017 at 3:57 pm

    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. […]

  • Ventura fault could cause stronger shaking, new research finds
    on February 14, 2017 at 3:42 pm

    The fault under Ventura, California, would likely cause stronger shaking during an earthquake and more damage than previously suspected, researchers warn. The Ventura-Pitas Point fault in Southern California has been the focus of much recent attention because it is thought to be capable of magnitude 8 earthquakes. It underlies the city of Ventura and runs offshore, and thus could generate tsunamis. […]

  • Southern Italy: Earthquake hazard due to active plate boundary
    on January 24, 2017 at 4:15 pm

    Tectonically, the Mediterranean is extremely active and thus threatened by natural catastrophes. Over the last few years an international team of researchers has intensively studied the seafloor south of Sicily and Calabria.

  • Marine biologists observe sea life after the 2011 tsunami
    on December 13, 2016 at 4:56 pm

    The tsunami of 2011 is well remembered in Japan. Some towns have recovered, while others struggle to return to a life that once was. The same is true for ecosystems. Researchers report how the sea life in different coastal regions of Japan struck by the tsunami have flourished or faltered. […]

  • Subduction zone geometry: Mega-earthquake risk indicator
    on November 24, 2016 at 8:02 pm

    Mega-earthquakes (with a magnitude greater than 8.5) mainly occur on subduction faults where one tectonic plate passes under another. But the probability of such earthquakes does not appear to be even across these zones. In a new study, researchers show that mega-earthquakes mostly occur on the flattest subduction zones. Thus, the Philippines, Salomon Islands and Vanuatu areas would not be favorable to mega-earthquakes, unlike South America, Indonesia and Japan. The discovery of this new indicator should improve earthquake monitoring and seismic and tsunami risk prevention. […]
