Deep-ocean researchers target tsunami zone near Japan
Rice University Earth scientist Dale Sawyer and colleagues last month reported the discovery of a strong variation in the tectonic stresses in a region of the Pacific Ocean notorious for generating devastating earthquakes and tsunamis in southeastern Japan. view more (2008-01-18)
UCL scientists create first earthquakes in the laboratory
Scientists at UCL have recreated earthquakes in the laboratory for the first time allowing them to better understand the origin of the largest and most violent earthquakes. This is the first time scientists have been able to generate and observe deep and intermediate focus earthquakes in the laboratory, recreating the exact pressure and... view more... (2002-11-14)
Scientists gain new insights into 'frozen' methane beneath ocean floor
An international team of scientists supported by the Integrated Ocean Drilling Program (IODP) has completed a unique research expedition aimed at recovering samples of gas hydrate, an ice-like substance hidden beneath the seafloor off Canada's western coast. view more (2005-11-01)
Study of 2004 tsunami forces rethinking of giant earthquake theory
The Sumatra-Andaman earthquake of Dec. 26, 2004, was one of the worst natural disasters in history, largely because of the devastating tsunami that followed. view more (2006-03-06)
Investigating the deepest layers of the Earth's crust
The deep layers of the Earth's crust and the upper part of its mantle have been the target for investigation by a number of research groups at the EHU/UPV. This deep zone, and the processes that have taken place there in the past, can be investigated by means of studying those rocks which today are lying on the surface but which in past geological... view more...

Pacific Northwest tectonic plates are moving
he three major tectonic plates off the Pacific Northwest coast are undergoing a gradual shift, and the area in which they converge - popularly known as the "Triple Junction" - appears to be migrating in a southeasterly direction. view more (2006-04-12)
Frozen Natural Gas Discovered at Unexpectedly Shallow Depths Below Seafloor
An international team of research scientists has reported greater knowledge of how gas hydrate deposits form in nature, subsequent to a scientific ocean-drilling expedition off Canada's western coast. view more (2006-08-22)
Tiny tremors and earthquakes provide intriguing clues about seismic activity, study finds
The elusive science of earthquake prediction has been reinvigorated in recent years with the discovery of "non-volcanic tremors"—faint vibrations that originate deep inside active fault zones. view more (2006-07-13)
NOAA and Louisiana scientists predict largest Gulf of Mexico 'dead zone' on record
NOAA-supported scientists from the Louisiana Universities Marine Consortium and Louisiana State University are forecasting that the "dead zone" off the coast of Louisiana and Texas in the Gulf of Mexico this summer could be the largest on record. view more (2008-07-16)
Scientists launch deep-sea scientific drilling program to study volatile earthquake zone
Today, the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) gets underway, with the Japanese drilling vessel Chikyu departing from Shingu Port with scientists aboard, all ready to log, drill, sample, and install monitoring instrumentation in one of the most active earthquake zones on Earth. view more (2007-09-21)
Biofuel production could undercut efforts to shrink Gulf 'Dead Zone'
Scientists in Pennsylvania report that boosting production of crops used to make biofuels could make a difficult task to shrink a vast, oxygen-depleted "dead zone" in the Gulf of Mexico more difficult. view more (2009-09-17)
Amadeus and Esmeraldas: two marine geophysics campaigns to investigate strong earthquakes off Ecuador and Colombia
Several large earthquakes with magnitude higher than 8 on the Richter scale have already occurred along the margins between the Nazca and South American tectonic plates, under the ocean off Ecuador and Colombia. This region is vulnerable, all the more so because since the 1980s, Ecuador's oil export terminal is sited within it. More information is... view more... (2005-02-16)
Geologist plans volcano safety for Ecuadorians
A geologist at Washington University in St. Louis is doing his part to make sure that the small Latin American country of Ecuador follows the Boy Scout motto: Be prepared. view more (2007-08-22)
European coastal zone management becomes hot item
The Institute for Environmental Studies of the Vrije Universiteit Amsterdam is to organise jointly with the University of East Anglia a four-day workshop on the future of European coastal zone management, at the invitation of the European Commission. From Monday, 4 June to Thursday, 5 June, a group of fifty European coastal zone managers,... view more... (2003-05-22)
'Ultrasound' of Earth's crust reveals inner workings of a tsunami factory
Research announced this week by a team of U.S. and Japanese geoscientists may help explain why part of the seafloor near the southwest coast of Japan is particularly good at generating devastating tsunamis, such as the 1944 Tonankai event, which killed at least 1,200 people. The findings will help scientists assess the risk of giant tsunamis in... view more... (2007-11-16)
New report says human tampering threatens planet's life-sustaining surface
In a report released today, scientists call for a new systematic study of the Earth's "critical zone"-the life-sustaining outermost surface of the planet, from the vegetation canopy to groundwater and everything in between.Understanding and predicting responses to global and regional change is necessary, they say, to mitigate the impacts... view more...

Unusual mechanism of the Ambrym and Pentecost Islands earthquake in Vanuatu
The Vanuatu island arc, in the South-West Pacific, is 1 700 km long. It corresponds to a convergence zone where the Australian plate is slipping eastwards under the North Fiji Basin, which is part of the Pacific plate, thus generating earthquakes. On 26 November 1999, the central islands of Vanuatu, particularly Ambrym and Pentecost, were strongly... view more... (2004-02-20)
Stress Buildup Precedes Large Sumatra Quakes
The island of Sumatra, Indonesia, has shaken many times with powerful earthquakes since the one that wrought the infamous 2004 Indian Ocean tsunami. Now, scientists from the California Institute of Technology and the Indonesian Institute of Sciences are harnessing information from these and earlier quakes to determine where the next ones will... view more...

Living close to heavy industry may increase risk of lung cancer
Living close to heavy industry may increase the risk of developing lung cancer, although the effect is relatively modest, suggests research published ahead of print in Thorax. view more (2006-09-28)
Silent earthquakes may foreshadow destructive temblors, study finds
A team of American geoscientists is urging colleagues around the world to search for evidence of tiny earthquakes in seismically active areas, such as the Pacific Northwest, that are periodically rocked by powerful temblors of magnitude 8 and higher. view more (2006-07-06)
