Because of the great depth of the earthquake a tsunami is not expected and there should also be no major damage due to shaking.
Most recent large event: Sea of Okhotsk
Origin time: 2013-05-24 05:44:49 UTC
Epicenter: 153.24°E 54.89°N
Depth: 605 km
Professor Frederik Tilmann of the GFZ German Research Centre for Geosciences: "The epicenter is exceptionally deep, far below the earth's crust in the mantle. Such strong earthquakes at this depth generally occur only in a few places in the world: namely where geologically old oceanic plates with more than 80 million years of age push quickly under another plate.”
Because of their age, these plates are comparatively cold and remain cool even at great depths if they also descend quickly. The temperature of the plates stays below 650 to 700 °C, the highest temperature at which rocks can break rapidly in an earthquake rather than deforming. In the case of the Okhotsk-earthquake, the Pacific plate moves at a speed of about eight centimeters per year underneath the Okhotsk microplate.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
