This aftershock is NNW of the 7.1 quake - note it is also shallow. It's right on the coastline.

Quake caused color change in the waters of Lake Nahuel Huapi

A singular phenomenon occurred in the waters of Lake Nahuel Huapi Patagonia, near Bariloche. As indicated by Yahoo , witnesses indicated that there would be changes in the color and transparency of the lake, which is probably due to the earthquake felt on Sunday the central-south of our country.

Experts point out that a similar phenomenon occurred in the vicinity of San Martin de los Andes after the great earthquake of February, so the CONICET volcanologist based in Bariloche, Gustavo Villarrosa, told the state agency Telam, together specialists from the Nahuel Huapi National Park, made a flyby of the lake to see from the air surface color change, how it grows and how it moves across the lake.

As reported in the waters of the lake is noted a wide swath, lighter than the usual color of the lake, on the east coast of Bariloche, which was expanded to cover more than half of that header.

Villarosa said it would have a direct relationship with the quake late Sunday, with its epicenter in the Araucan?a region, adding that there are layers of coarse sediments, fine, volcanic ash, that before a quake can get suspended, and thus be more days, causing the phenomenon on Lake Nahuel Huapi.
