Tsunamis could cause beach tourism to lose hundreds of millions of dollars every year

Thu, 12 Apr 18 00:09:30 -0700

Going to the beach this summer? European tourists are more frequently going to places with significant tsunami risk, researchers have found. A global tourism destination risk index for tsunamis was released today at the 2018 Annual Conference of the European Geosciences Union in Vienna. It is based on a study led by Andreas Schaefer of Karlsruhe Institute of Technology (KIT) that examined all prominent tourism destinations globally with regard to the potential impact for businesses.



Modeling future earthquake and tsunami risk in southeast Japan

Mon, 02 Apr 18 00:06:50 -0700

Geoscience researchers at UMass Amherst, Smith College and the Japanese Agency for Marine-Earth Science and Technology unveil new, GPS-based methods for modeling earthquake-induced tsunamis for southeast Japan along the Nankai Trough. A Nankai-induced tsunami is likely to hit there in the next few decades, says lead author Hannah Baranes at UMass Amherst, and has the potential to displace four times the number of people affected by the massive Tohoku tsunami of 2011.



Calculating the impacts of natural events on wildlife

Fri, 30 Mar 18 00:12:00 -0700

A new method could help scientists understand how wildlife populations are affected by major natural events, such as hurricanes, severe winters, and tsunamis.



Why the seafloor starts moving

Tue, 13 Feb 18 00:03:00 -0800

When the seabed loses its stability and starts to move, it often happens in much larger dimensions than landslides ashore -- and at slopes with very low gradients. At the same time, discplacement of large amounts of sediment under water scan cause devastating tsunamis. However, why and when submarine landslides develop is hardly understood. Marine scientists from GEOMAR Helmholtz Centre for Ocean Research Kiel have now published possible causes based on observations on submarine landslides off the coast of northwest Africa in the international journal Geology.



Tiny fossils, huge slides: Are diatoms the key to Earth's biggest slides?

Mon, 12 Feb 18 00:03:40 -0800

The biggest landslides on Earth aren't on land, but on the seafloor. These mega-slides can move thousands of cubic kilometers of material, and sometimes trigger tsunamis. Yet, remarkably, they occur on nearly flat slopes of less than three degrees.



Satellite-based earthquake early warning system tested against Chilean great quakes

Tue, 06 Feb 18 00:03:50 -0800

Researchers testing a satellite-based earthquake early warning system developed for the US West Coast found that the system performed well in a 'replay' of three large earthquakes that occurred in Chile between 2010 and 2015.



Could underwater sound waves be the key to early tsunami warnings?

Wed, 24 Jan 18 00:06:20 -0800

Mathematicians have devised a way of calculating the size of a tsunami and its destructive force well in advance of it making landfall by measuring fast-moving underwater sound waves, opening up the possibility of a real-time early warning system.



Will there be enough public health workers when baby boomers retire?

Wed, 17 Jan 18 00:14:10 -0800

In a study in the American Journal of Preventive Medicine, researchers estimate that over one quarter of the governmental public health workforce will disappear. They further project that while enough students graduate each year to replace retirees and others who voluntarily quit, they question whether the public health sector can compete with the private sector to hire qualified candidates.



A society divided by reconstruction

Fri, 12 Jan 18 00:06:50 -0800

In 2004, a tsunami devastated much of the Indonesian city of Banda Aceh. An international team of researchers has studied the long-term impact that rebuilding efforts in coastal areas have had on the community.



Small Ontario municipalities least prepared to support aging adults

Thu, 21 Dec 17 00:11:20 -0800

Small municipalities in Ontario are less likely than larger centres to be able to accommodate the needs of their aging populations, according to a report from the University of Waterloo.



Residual strain despite mega earthquake

Wed, 13 Dec 17 00:10:50 -0800

On Christmas Day 2016, the earth trembled in southern Chile. In the same region, the strongest earthquake ever measured occurred in 1960. A comparison of data from seismic and geodetic measurements during and after both earthquakes shows that the energy released by the 2016 quake accumulated over more than 56 years. According to this, the 1960 quake, despite its immense strength, must have left some strain in the underground. The study has now been published in the journal Geophysical Journal International.



Antibiotics resistance: Researchers succeed to block genes of resistance

Wed, 22 Nov 17 00:05:30 -0800

Scientists at Université de Montreal's Department of Biochemistry and Molecular Medicine design better molecules that make it harder for plasmids to move between bacteria.



Seafloor sediments appear to enhance Earthquake and Tsunami danger in Pacific Northwest

Mon, 20 Nov 17 00:11:20 -0800

The Cascadia Subduction Zone off the coast of the Pacific Northwest has all the ingredients for making powerful earthquakes -- and according to the geological record, the region is due for its next 'big one.' A new study led by The University of Texas at Austin has found that the occurrence of these big, destructive quakes and associated devastating tsunamis may be linked to compact sediments along large portions of the subduction zone.



Researchers create largest, longest multiphysics earthquake simulation to date

Mon, 13 Nov 17 00:10:30 -0800

A multi-disciplinary team of researchers from LMU and TUM in Munich simulated the largest, longest multiphysics earthquake simulation to date at the Leibniz Supercomputing Centre. Its work is up for best paper at SC17.



UK elimination of hepatitis C in jeopardy unless more patients found

Tue, 31 Oct 17 00:09:00 -0700

Just one in three people with hepatitis C in the UK have been diagnosed according to the latest estimates released at this year's World Hepatitis Summit in Sao Paulo, Brazil.



Tsunami reveals human noise pollution in Hawaiian waters

Mon, 30 Oct 17 00:06:10 -0700

Spinner dolphins in bays along Hawaii's Kona Coast are subjected to underwater sound levels more than 16 times louder than natural due to noise pollution from ecotourism, sonar exercises and other human activities in the bays, a Duke University-led study finds. A tsunami struck the islands' coastal waters during the study and temporarily halted most human activities there, providing scientists with a rare comparative glimpse into what the bays sound like without these disruptions.



Ancient skull likely to belong to world's oldest tsunami victim

Wed, 25 Oct 17 00:07:50 -0700

A new geological analysis of the site where a 6000-year old human skull was discovered in Papua New Guinea in 1929 has revealed that the person most likely died in a catastrophic tsunami. The researchers found the place where the Aitape Skull was unearthed was a coastal lagoon that was inundated by a large tsunami about 6000 years ago, similar to the one that struck nearby with such devastating effect in 1998, killing more than 2000 people.



6,000-year-old skull could be from the world's earliest known tsunami victim

Wed, 25 Oct 17 00:07:20 -0700

Scientists have discovered what they believe is the skull of the earliest known tsunami victim, a person who lived 6,000 years ago in Papua New Guinea. The skull itself was found almost a hundred years ago, but recent analysis of the sediments found with the skull reveals that they bear distinctive hallmarks of tsunami activity.



Aitape skull likely belongs to world's oldest tsunami victim

Wed, 25 Oct 17 00:07:10 -0700

New research from the University of Notre Dame suggests the bone fragment belongs to the world's oldest known tsunami victim -- an important piece in the conversation about how modern populations can adapt to rising sea levels.



Moment of impact: A journey into the Chicxulub Crater

Mon, 23 Oct 17 00:02:20 -0700

When the Chicxulub asteroid slammed into Earth about 66 million years ago, it obliterated 80 percent of Earth's species, blasted out a crater 200 kilometers across, and signaled an abrupt end to the Cretaceous Period. The impact, its catastrophic effects, and its aftermath have engrossed scientists and the public alike since it was first discovered.



New magma pathways after giant lateral volcano collapses

Mon, 23 Oct 17 00:04:10 -0700

Giant lateral collapses are huge landslides occurring at the flanks of a volcano. Such collapses are rather common events during the evolution of a large volcanic edifice, often with dramatic consequences such as tsunami and volcano explosions. These catastrophic events interact with the magmatic activity of the volcano, as a new research by scientists of GFZ German Research Centre for Geosciences in Nature Communications suggests.



Risk of tsunamis in Mediterranean Sea has been overstated

Wed, 11 Oct 17 00:13:20 -0700

A review of geological evidence for tsunamis during the past 4500 years in the Mediterranean Sea has revealed that as many as 90 per cent of these inundation events may have been misinterpreted by scientists and were due to storm activity instead.



New study analyzes volcanic fatalities in more detail than ever before

Fri, 06 Oct 17 00:04:50 -0700

Building on existing information and databases relating to volcanic fatalities, scientists from the University of Bristol have, for the first time, been able to classify victims by activity or occupation and look at the distance of their death from the volcano.



PSU study tracks potentially harmful species from Japanese tsunami to American shores

Tue, 03 Oct 17 00:15:30 -0700

Nearly 300 aquatic species have landed on American shores since the 2011 Japanese tsunami by hitching rides on manmade debris, according to a team of researchers from Portland State University and other institutions. Their findings about long-distance life rafting on debris and its impact on the environment were published in the Sept. 29 issue of the journal 'Science.'



How one tsunami and lots of manmade debris are triggering a mass marine migration

Thu, 28 Sep 17 00:12:30 -0700

Following the 2011 East Japan tsunami, more than 280 coastal marine species have been recorded crossing the Pacific by hitching a ride on debris, a new study reveals.



Non-native species from Japanese tsunami aided by unlikely partner: Plastics

Thu, 28 Sep 17 00:11:30 -0700

Study confirms large earthquakes along Olympic Mountain faults

Wed, 27 Sep 17 00:00:20 -0700

A comprehensive study of faults along the north side of the Olympic Mountains of Washington State emphasizes the substantial seismic hazard to the northern Puget Lowland region. The study examined the Lake Creek-Boundary Creek and Sadie Creek faults along the north flank the Olympic Mountains, and concludes that there were three to five large, surface-rupturing earthquakes along the faults within the last 13,000 years.



New technique spots warning signs of extreme events

Fri, 22 Sep 17 00:07:10 -0700

Engineers at MIT have devised a framework for identifying key patterns that precede an extreme event. The framework can be applied to a wide range of complicated, multidimensional systems to pick out the warning signs that are most likely to occur in the real world.



Rogue wave analysis supports investigation of the El Faro sinking

Tue, 19 Sep 17 00:01:00 -0700

A new analysis done to support the investigation into the 2015 sinking of the El Faro cargo ship has calculated the likelihood of a massive rogue wave during Hurricane Joaquin in October of that year -- and demonstrated a new technique for evaluating the probability of rogue waves over space and time.



2011 Tohoku-oki earthquake: Results from seismic reflection data

Tue, 05 Sep 17 00:11:40 -0700

A striking finding of the 2011 Tohoku-oki earthquake (Mw 9.0) is that more than 50 meters of coseismic fault slip reached the trench axis. In addition to this, seismological studies found a clear depth-dependent variation in the source location between high- and low-frequency seismic energy radiation. However, structural features that may control the slip behavior in the rupture zone have not been well examined.

Wed, 30 Aug 17 00:16:10 -0700

International research team shows negligible risk from consumption of meat from migratory marine predators following Fukushima nuclear disaster.



The losses that come after the earthquake: Devastating and costly

Fri, 25 Aug 17 00:02:10 -0700

The study, titled, 'Losses Associated with Secondary Effects in Earthquakes,' published by Frontiers in Built Environmen, looks at the devastation resulting from secondary disasters, such as tsunamis, liquefaction of sediments, fires, landslides, and flooding that occurred during 100 key earthquakes that occurred from 1900 to the present. And unlike previous studies, Daniell et al put a dollar value to the devastation from these secondary causes.



New images from under Alaska seafloor suggest high tsunami danger

Tue, 01 Aug 17 00:07:50 -0700

Scientists probing under the seafloor off Alaska have mapped a geologic structure that they say signals potential for a major tsunami in an area that normally would be considered benign. They say the feature closely resembles one that produced the 2011 Tohoku tsunami off Japan, killing some 20,000 people and melting down three nuclear reactors. Such structures may lurk unrecognized in other areas of the world, say the scientists. The findings appear today in the print edition of the journal Nature Geoscience.



Group relocation preserves social connections among elderly Japanese Tsunami survivors

Wed, 26 Jul 17 00:14:20 -0700

Relocating in groups, rather than individually, increased informal socializing and social participation among older survivors of the 2011 Great East Japan Earthquake and Tsunami, a new study shows. The finding suggests local authorities should consider moving residents



Sea cave preserves 5,000-year snapshot of tsunamis

Wed, 19 Jul 17 00:13:10 -0700

An international team of scientists digging in a sea cave in Indonesia has 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.

Japanese slow earthquakes could shed light on tsunami generation

Thu, 15 Jun 17 00:15:00 -0700

Understanding slow-slip earthquakes in subduction zone areas may help researchers understand large earthquakes and the creation of tsunamis, according to an international team of researchers that used data from instruments placed on the seafloor and in boreholes east of the Japanese coast.



Slow earthquakes in ocean subduction zones shed light on tsunami risk

Thu, 15 Jun 17 00:13:50 -0700

Understanding 'slow-slip' earthquakes on the seafloor -- seismic events that occur over a period of days or weeks -- is giving researchers new insights into undersea earthquakes and the subsequent creation of tsunamis. Through an ocean discovery program supported by the National Science Foundation (NSF), scientists are studying the seafloor off the coast of Japan. The region could provide vital clues.



Emphasizing individual solutions to big issues can reduce support for government efforts

Tue, 13 Jun 17 00:07:50 -0700

Experiments by political science graduate student Seth Werfel suggest that making individuals aware of how they can help solve large-scale problems makes them less likely to support government-based solutions.



New evidence reveals source of 1586 Sanriku, Japan tsunami

Tue, 06 Jun 17 00:05:40 -0700

A team of researchers, led by Dr. Rhett Butler, geophysicist at the University of Hawai'i at Mānoa (UHM), 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.



Sediment from Himalayas may have made 2004 Indian Ocean earthquake more severe

Thu, 25 May 17 00:13:00 -0700

Sediment that eroded from the Himalayas and Tibetan plateau over millions of years was transported thousands of kilometers by rivers and in the Indian Ocean -- and became sufficiently thick over time to generate temperatures warm enough to strengthen the sediment and increase the severity of the catastrophic 2004 Sumatra earthquake.



Researchers drill deep to understand why the Sumatra earthquake was so severe

Thu, 25 May 17 00:11:00 -0700

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.



Disaster risk management: Science helps save lives

Wed, 24 May 17 00:01:40 -0700

Natural and man-made disasters threaten millions of people every year and cause billions of property damage. How much do we know about them? And how can we use that knowledge to save lives and money? A recent report, compiled by the European Commission's Science and Knowledge Service (JRC), seeks to answer these and other questions and to help prepare for the time when disaster strikes.



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