New study of earthquakes reveals secrets about the earth's fluid mantle

A new study from a University of Chicago scientist suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle.

The finding was made by measuring the lingering movement registered by GPS sensors on islands in the wake of a deep earthquake in the Pacific Ocean near Fiji. Published Feb. 22 in Nature, the study demonstrates a new method to measure the fluidity of the Earth's mantle.

"Even though the mantle makes up the largest part of Earth, there's still a lot we don't know about it," said Sunyoung Park, a geophysicist with the University of Chicago and the lead author on the study. "We think there's a lot more we can learn by using these deep earthquakes as a way to probe these questions."

mmmmmm
The number of people killed by the earthquakes that struck Turkey and Syria earlier this month has now passed 50,000, according to the latest figures from both countries.

In Turkey alone, 44,218 people died as a result of the earthquakes, the country's Disaster and Emergency Management Authority (AFAD) said on Friday, while the latest announced death toll in Syria was 5,914.

The first earthquake on February 6 that hit southeastern Turkey and northern Syria measured a magnitude of 7.7 and a second, a little later, measured 7.6. The region has been rocked by more than 9,000 aftershocks since, according to the AFAD.

Nearly 240,000 rescue workers, including volunteers, continue to work in the 11 quake-hit provinces in Turkey. Some of the areas affected by the quakes were initially difficult to access but recovery efforts continue and casualty numbers are rising as they progress.

There have been no reports of survivors being rescued in recent days.
