Now it can be told: Massive earthquake occurred four months ago off the coast of Russia

I’ll bet you didn’t know about THIS:

It’s confirmed: The largest deep earthquake ever recorded happened in May off the coast of Russia [above]. But this massive temblor is still a mystery to scientists.

The magnitude-8.3 earthquake occurred on May 24, 2013, in the Sea of Okhotsk, deep within the Earth’s mantle. The earthquake, described today (Sept. 19) in the journal Science, is perplexing because seismologists don’t understand how massive earthquakes can happen at such depths.

“It’s the biggest event we’ve ever seen,” said study co-author Thorne Lay, a seismologist at the University of California, Santa Cruz. “It looks so similar to shallow events, even though it’s got 600 kilometers of rock on top of it. It’s hard to understand how such an earthquake occurs at all under such huge pressure.”

The Sea of Okhotsk earthquake occurred about 378 miles (609 km) beneath the Earth’s surface, at a crack where the Pacific Plate was pressing into the mantle, the layer of hot, plastic rock that sits below the crust. Despite the depth at which it occurred, the quake was felt by people in Russia. (There were no injuries or property damage.)

By analyzing global seismological data, researchers determined that the quake was the biggest deep earthquake ever recorded. A prior deep earthquake, in Bolivia in 1994, was the same magnitude, but released less energy.

  1. Our world is hollow like all the planets and the moons, and has an inner sun.
    The core is about 800 miles and the gravity is at both sides of the earth`s core and this explains this kind of strange earth-quakes.
