Scientists at the Technische Universität (TU) Dresden have discovered massive post-glacial rebound in the Patagonian ice field at the southern tip of South America. Together with their colleagues from Chile and the USA, the researchers can prove the land is actually moving upward as the glaciers that once weighed it down melt away.

Using GPS technology, the Patagonia-based team measured the largest post-glacial rebound anywhere in the world thus far, an exact rate of 39 mm per year. Spanning more than 5,000 square miles, the southern Patagonian ice field is the worlds second largest ice mass in the southern hemisphere after Antarctica.

Two factors are coming together here, explains project manager Reinhard Dietrich from the Institute for Planetary Geodesy at the TU Dresden.

First the decrease of the ice, which began after the small ice age about 120 years ago which has now reached a major annual loss of 30 gigatons or about 30 cubic kilometers. This increasing loss of ice is clearly associated with climate change that has occurred over recent decades. Secondly, the lithosphere and earth mantle have the properties to compensate especially quickly for massive changes on the earths surface.”

This compensation process is known by the scientific term glacial isostasy. The earth’s crust sits atop a layer of very hot rock known as the mantle, which can stretch and flow under pressure. The weight of the glaciers once displaced some of the the mantle below, but as the ice melts away, the mantle is flowing back and pushing the crust upwards.

on what to do in case of a quake.
These clouds seemed to be glowing or somewhat luminous and seemed to resemble some characteristics of the Auroras. This scientists is willing to give a full explanation. This is pressure on the rocks causing a static discharge or radio/digital wave from the earth before a great quake.
