Last update: April 6, 2011 at 11:24 pm by By

Hundreds of articles have been written the last couple of days on the Sendai tsunami and earthquake.
The links below are meant to make it easier for our readers to understand what happened.

Tectonic Interplay Beneath Japan Gradually Unmasked
In the aftermath of the massive earthquake that struck Japan on March 11, geologists, physicists and planetary scientists have began an ample campaign to determine what went wrong with the tectonic plates that ruptured during the magnitude 9.0 disaster.

Seismologists urge creation of earthquake early warning system along Pacific Coast
“Japan’s earthquake early warning system undoubtedly saved thousands of lives, and will reduce the long-term impact of the earthquake on the economy,” said Allen, who has been working for nearly a decade to develop and test an earthquake early warning system in the United States. “A similar system in California could provide as much as a minute warning – and in Washington, as much as two-to-three minutes’ warning – so that some actions, many of them automated, can be taken before the destructive waves (of shaking) arrive.”

Japan Tsunami Warnings From Ancestors Were Forgotten
Modern sea walls failed to protect coastal towns from Japan’s destructive tsunami last month. But in the hamlet of Aneyoshi, a single centuries-old tablet saved the day.

Japan Earthquake: A Horizon Special with Iain Stewart
Professor Iain Stewart examines the powerful geological forces that unleashed the devastating Japanese earthquake, and explores how the release of this power of the planet brought Japan to the brink of a nuclear meltdown.

Earthquake triggering, and why we don’t know where the next big one will strike
Does that mean that the Japanese earthquake caused increased risk on the San Andreas Fault, or any other?

Lessons from the Japan Earthquake
Chris Scholz, a Lamont-Doherty Earth Observatory professor with decades of experience looking at how earthquakes work, said he had thought a 9.0 magnitude quake like the one that struck near Sendai, Japan, was “impossible” in that area. Follow his 5 minute explanation of the relation from the present earthquake with historic earthquakes.

French-Turkish researchers detect early quake signals
Franco-Turkish researchers have found that a deadly 1999 earthquake in Turkey was preceded by seismic signals, raising hopes of a predictive system for future tremors as Japan reels from its disaster.

Can geothermal help Japan in crisis?
Japan is sitting on enough untapped geothermal power to replace all its planned nuclear stations over the next decade.

Japan’s Tsunami Topped 70 Feet in One Estimate
Video footage of the tsunami that hit Japan this month makes it clear: This was no ordinary wave. And now t

here are initial estimates for just how high it reached — nearly 80 feet in at least one place.

How earthquakes work”a nice video demonstration
I tried to explain a little bit about why earthquakes happen at subduction zones, like the one near the coast of Japan. Lacking props, I used my hands to mock up the motion of one tectonic plate sliding beneath another. This video”made by science blogger Matt Kuchta”does a much better job of demonstrating the same thing.

Tsunami™s lessons
The malevolent earthquake and tsunami in Japan have jolted our minds back to the 2004 catastrophe in the Indian Ocean, as well as to last year™s tsunamis in Chile and Sumatra.

New fault line stress could trigger Tokyo earthquake
Geologists say a powerful earthquake could strike near Tokyo because the recent monster that hit northeastern Japan altered the earth™s surface, loading stress onto a segment of the fault line near the capital.

Japan™s Drilling Vessel Chikyu Damaged By Tsunami
Japan™s monster ship also called œGodzilla-maru because of its 210 m length and a drill derrick that rises 100 m off the deck. The rig dwarfs the Statue of Liberty, nearly matches the height of the St. Louis arch.

Why earthquakes are hard to predict ?
New Scientist explains why earthquakes are so hard to predict, how seismologists have tried to foretell quakes in the past, and what promising approaches may lead to successful prediction in the future.

Engineers™ goal is tsunami-resistant buildings
Buildings can be created to withstand the most powerful earthquakes, but designers remain largely powerless in thwarting the destructive forces of a tsunami, such as the one that slammed Japan™s northeast coast Friday. A group of engineers hopes to change that.

Seawalls Offered Little Protection Against Tsunami’s Crushing Waves
At least 40 percent of Japan’s 22,000-mile coastline is lined with concrete seawalls, breakwaters or other structures meant to protect the country against high waves, typhoons or even tsunamis.

Sanriku: Japan’s ‘Tsunami Coast’
This hauntingly beautiful area has battled the furies of nature for centuries

AIR™s Japan Quake/Tsunami Insured Loss Estimates: $15 Billion to $35 Billion
Boston-based catastrophe modeling firm AIR Worldwide™s most recent statement, based on œcurrently available information, estimates that insured property losses from the Mw9.1 earthquake that struck Japan on Friday will range between 1.2 trillion JPY to 2.8 trillion JPY.

Scientists Develop New Tool to Predict Earthquakes
esearchers have developed a new tool called “fossil seismograph” that helps better predicting of future earthquakes by studying earthquakes of the ancient past.
