Chinese geologists suggest that earthquakes can be triggered by reservoirs in a study of the Zipingpu Reservoir and Longmenshan Slip.

The extended Coulomb failure stress (ECFS) criteria and anisotropic porosity and permeability tensor at micro/meso/macro scale under ultra‑high temperature and pressure (UTP) conditions were developed employing the flow driven pore‑network crack (FDPNC) model under multiple temporal–spatial scales and the hybrid hypersingular integral equation‑lattice Boltzmann method (HHIE‑LBM). The correlation of the Zipingpu reservoir and Longmenshan slip was then analyzed and the fluid–solid coupled three‑dimensional facture mechanism of the reservoir and earthquake fault was explored.

Scientists Aglow After Big Discovery During Tsunami

Researchers using a camera on Maui have photographed the glow from atmospheric pressure disturbances generated by the March 11 tsunami, raising hopes that the technique could be used to predict the arrival of future waves.

The first observation of its kind was made from the Air Force Maui Optical and Supercomputing Station atop Haleakala by scientists in France, Brazil and the United States.

The March 11 earthquake in Japan generated a seismic sea wave that devastated parts of northern Honshu and caused millions of dollars of damage in Hawaii.

On the open ocean, such waves move at 500 mph but are only an inch high. Nevertheless, they put pressure on the atmosphere, scientists say.

“The atmosphere gets less and less dense as you get higher, and that allows the Read more…

Following its discovery by US intelligence officers, Tehran has acknowledged the existence of the underground bunker at Fordow, a shelter designed to see uranium enrichment from current claims of 20 percent to the 90 percent purity required of a nuclear weapon.

The bunker is designed to withstand air and missile strikes so the mere acknowledgement of its existence does not necessarily threaten it, which is why Iran has acknowledged it publicly. Nevertheless, some experts claim that up to 90 percent of Iran is covered by fault lines, a safety risk more pronounced after the devastation at Read more…

An earthquake with a magnitude of 3.9 has struck in the English Channel, the British Geological Survey (BGS) said.

The quake had a depth of 10km and its epicentre was south of Portsmouth, according to the BGS.

Residents in parts of West Sussex reported buildings shaking for a few seconds at about 0800 BST.

Sussex Police, Solent Coastguard and West Sussex Fire and Rescue Service said they had not been called out to any incidents related to it.

Straw Fed To Japanese Found To Be Radioactive

MINAMISOMA, JAPAN (BNO NEWS) — Japan’s nuclear crisis has spread to its cattle as high levels of radioactive cesium were detected at a farm in Fukushima, officials said Monday.

The radioactive cesium was found in straw fed to cattle at a farm in Minamisoma, Fukushima Prefecture with an average of 75,000 becquerels of the radioactive isotope per kilogramme (2.25 pounds), which is about 56 times the allowable limit, Kyodo news agency reported.

According to officials, the contaminated straw was stored in an exposed area of the farm without roofs during the March 11 earthquake and tsunami that caused a series of explosions that crippled the Fukushima Daiichi nuclear power plant. Furthermore, the farm is located in one of the high-risk areas of the region, and officials suspect the straw could be the radioactive source of contaminated beef that had been detected in meat shipped from that area.

The contaminated meat of eleven cows was detected in Tokyo, where the meat was shipped for processing. However, at the time of the shipment, the Read more…

Big-Time 7.8 Earthquake Strikes Off New Zealand

The earthquake is a 7.8, and it’s that big red dot in the Pacific, near New Zealand.

There are tsunami fears. Warnings are in effect for Tonga and the Kermadec Islands, according to the Pacific Tsunami Warning Center.

The New Zealand dollar is falling a bit on the news. You can see the big dropoff on the Kiwi on this chart.

Scientists warn volcanoes in Australia are due to erupt

Scientists are now warning that volcanoes in Western Victoria and South Australia are due to erupt. The prediction comes just hours after two earthquakes hit the state this morning.

Using new dating techniques, University of Melbourne scientists have found that the volcanoes usually erupt every 2000 years, with the last eruption at Mt Gambier, South Australia, 5000 years ago. It comes as Victorians are warned to brace themselves for more tremors after a shallow magnitude quake hit at 11.32am, sending shockwaves through towns and suburbs more than 100 kilometres away. A series of tremors lasting up to 15 seconds have been felt across Melbourne’s CBD and southeastern suburbs. A second, smaller quake shook Korumburra, with reports it was again felt in Melbourne, at 12.37pm

Some Victorians say their houses shook violently for about 10 seconds, and many reported hearing the earth rumble. Experts say the quake struck 8 kilometres underground, and said the epicentre was about 7km west of Korumburra.  So far, there are no reports of any major damage, except hairline cracks in some peoples’ homes. The area in Gippsland is prone to Read more…

California Mega-Quake Imminent Say Scientists

The San Andreas fault is highlighted in red. It strikes through the heart of Southern California, including the Salton Sea.

Like a steaming kettle with the top on, pressure is building beneath the surface of California that could unleash a monster earthquake at any time. That’s according to a new study from the Scripps Institute of Oceanography.

Geologists say Southern California is long overdue for a huge earthquake that could unleash widespread damage.

It all comes down to the Salton Sea, which lies to the east of San Diego. The Salton Sea lies directly on the San Andreas Fault and covers more than 350 square miles.

A big earthquake has hit the lake bed about every 180 years. But when officials started damming the Colorado River to reduce floods downstream (including in the Salton Sea), the moderate earthquakes stopped for the Salton.

Sounds like a good thing, right? Not necessarily. Seismologists think the Read more…
