Oregon Coast’s Vulnerability

The northwestern coast of Oregon is susceptible to both local and far-field tsunamis. The Cascadia Subduction Zone, where the eastward moving Juan de Fuca plate meets the westward moving North American Plate, is just off the Pacific Northwest coast of the United States and Canada. It is a 750-kilometer long fault zone. This area is very active tectonically, and therefore has the potential to produce large earthquakes and possibly, subsequent tsunamis. This subduction zone is thought to have last ruptured in 1700.

Additionally, far-field earthquakes throughout the Pacific are also capable of spawning tsunamis that could eventually reach the Oregon coast. Historical records show that since 1812, about 28 tsunamis with wave heights greater than one meter have reached the U.S. west coast. The March 1964 “Good Friday” earthquake created the most devastating of these tsunamis. The epicenter of this earthquake was near Anchorage, Alaska. The tsunami that followed this earthquake reached coasts all along the western U.S. within six hours. Cannon Beach, a small coastal community in northwestern Oregon was inundated during Read more…

Volcano expert fears we’ll see a super eruption

Volcanologist Clive Oppenheimer yesterday warned there was a one-in-500 chance of the world being hit by a super- volcano this century.

The reader in vulcanology at Cambridge University told a Hay audience: “That might not sound like much, but it is a lot more likely than an asteroid impact.

“The events in Japan remind us that you can have a tsunami and earthquake and a nuclear plant there as well and you can have these chain reaction events that are actually quite calamitous and they are not unimaginable.”

Examining geological, historical and archeological records, the expert took the audience on a journey back to three volcanic eruptions that have shaken the world – the 1815 Tambora volcano in Indonesia that Read more…

TOKYO (AP) – An oil spill and a small explosion have caused limited damage – but no further radiation leaks – at the crippled nuclear power plant in northeastern Japan, the plant operator said Tuesday.

Workers at Fukushima Dai-ichi plant found an oil spill in the sea near reactors five and six, which were in shutdown when the earthquake and tsunami struck March 11, Tokyo Electric Power Co. said. The spill was contained by an oil fence, TEPCO spokesman Taichi Okazaki said.

The explosion workers heard at reactor four was Read more…

The 2012 Doom Factor (Video)

May 27, 2011 Comments off

In order to understand the future, you must study the past.  Many people wonder about what happened to these great ancient civilizations and their technology.   The above video has been out for a few years but goes into great depth on why we are seeing an unprecedented occurrence of anomalies in weather pattern changes, earthquakes, tornadoes, volcanic eruptions, mysterious animal deaths ect.  Turn off your TV, silence your cell phone and unplug yourself from anything that is distracting.  This video is very eye-opening and educational to say the least.  I am definitely not saying that the world will end in 2012; however there will be a global change in the near future.  Take this in perspective: Before a storm begins you will notice that the clouds begin to change, the wind gust becomes stronger, lightning will appear, and small raindrops begin to fall to the ground. Guess what?  This is the edge of the storm.  It is true when they say history repeats itself…

A new leak of radioactive water has been found at Japan’s Fukushima nuclear power plant, adding to the woes of the Asian country’s nuclear crisis.

Tokyo Electric Power Company (TEPCO), the operator of the plant, said on Thursday that up to 57 tons of contaminated water has leaked from a storage facility, Reuters reported.

The environmental group, Greenpeace, has criticized the Japanese government’s assessment of the contamination level, saying, “Radioactive hazards are not decreasing through dilution or dispersion of materials, but the radioactivity is instead accumulating in marine life.”

“Our data show that significant amounts of contamination continue to spread over great distances from the Fukushima nuclear plant,” the group added.

Greenpeace has also accused TEPCO of covering up the actual severity of the disaster in the Asian Read more…

Fukushima Reactor 1 melted down, 2 and 3 may have too

Yesterday, TEPCO, the company responsible for running the Fukushima nuclear reactors, released a provisional analysis of the events that occurred in Unit 1, one of the reactors that was active when the tsunami struck. In five stark pages, the report lays out the impact of the tsunami on the facility: water levels that plunged below the bottom of the fuel, a complete meltdown of the nuclear fuel, and extensive damage to the reactor vessel.

The new analysis was enabled by the recent installation of air purifiers that let personnel reenter the reactor control room for the first time. Once inside, they were able to recalibrate some of the instruments that have been monitoring the reactor core; Read more…

Reactor Rupture Could Slow Japan Plant Stabilization

May 12, 2011 Comments off

Coolant is escaping through a newly discovered opening in the Fukushima Daiichi nuclear power plant’s No. 1 reactor pressure vessel, a development that could slow efforts to prevent potential further radiation releases from the Japanese facility, Reuters reported on Thursday (see GSN, May 11).

Plant operator Tokyo Electric Power learned the container held less water than previously believed following repairs to monitoring equipment this week; the tank’s fluid quantity was roughly 16 feet short of the depth required to fully submerge atomic fuel if the material had remained in its intended position. The six-reactor site was severely damaged in the March 11 earthquake and tsunami that left more than 20,000 people dead or missing in Japan.

“There must be a large leak,” Tokyo Electric Power official Junichi Matsumoto said to reporters on Thursday. “The fuel pellets likely melted and fell, and in the process may have damaged … the pressure vessel itself and created a hole,” he said.

Ongoing water transfers have successfully curbed the escaped fuel’s temperature, though, and workers would keep pumping fluid into the system, Matsumoto said. The container’s water quantity suggests the rupture is likely several centimeters across, indicating the fuel might have made contact with the air early in the crisis, he said. The vessel’s surface heat level has Read more…

DHS Claims al-Qaeda May Replicate Fukushima Disaster

Instead of lessening terrorism, the supposed assassination of Osama bin Laden may result in a deliberate Fukushima-style nuclear disaster, according to the Department of Homeland Security.

On May 5, a Department of Homeland Security official at the Pacific Regional Information Clearinghouse in Hawaii presented a report entitled “Recreating Fukushima: A Possible Response to the Killing of Usama Bin Laden – The Nuclear Option.” It stated that “the death of [O]sama Bin Laden may serve as an impetus to apply lessons learned from Fukushima to attack the United States or another Western country.”

This would be accomplished, the report explains, by reproducing the failure of the electric supply that pumped cooling water to the reactors at the Fukushima Daiichi nuclear power plant in Japan. The official use only report says “the earthquake and tsunami in Japan were ‘acts of nature,’ but a catastrophic nuclear reactor meltdown could potentially be engineered by Al Qaeda” by Read more…

Fatalities from earthquakes are increasing worldwide but the chance of dying in a weather-related disaster is diminishing the United Nations said today.

The UN report also claimed economic losses from catastrophes are rising in all regions often due to a lack of investment

Damage to infrastructure – schools, health centres, roads, bridges – is soaring in many low- and middle-income countries despite improvements in many early warning systems, it said in the Global Assessment Report on Disaster Risk Reduction.

Rich countries are also increasingly exposed, with damage on the rise following floods in Australia and earthquakes in Japan and New Zealand already this year, it said.

“Progress is mixed,” UN Secretary-General Ban Ki-moon said in the report.

“The recent events in Japan point to new and catastrophic risks that need to be anticipated,” he warned, referring to the earthquake and tsunami in northeast Japan last March that triggered the worst nuclear crisis in 25 years.

Disasters have already caused more than $300 billion in losses so far this year, roughly the same as in all of 2010, a UN Read more…

Is this the age of megaquakes?

Buildings tossed together by the tsunami is seen in Miyagi Prefecture, northeastern Japan March 12, 2011. Scientists are asking if another megaquake will strike in the next six years.

By John Roach

First there was the earthquake and tsunami in Sumatra in 2004. Chile was shaken and lashed violently a year ago. Japan is still reeling from the twin disasters on March 11. It seems as if the Earth has woken from a long slumber and is violently re-jiggering its plates. Is there any truth to the notion?

The question of megaquake clustering, which I explored in the days following the 9.0 earthquake and tsunami in Japan, was a hot topic of conversation Thursday at the Seismological Society of America’s annual meeting in Memphis, Tenn., according to various media reports.

There, Charles Bufe, a seismologist retired from the U.S. Geological Survey in Denver, said the spate of recent megaquakes is very similar to a string of seven magnitude 8.5 or greater quakes that struck between 1950 and 1965. The intervening decades, he noted, were quiet.

Bufe and USGS colleague David Perkins analyzed the clustering and concluded that Read more…
