===Earthquakes===
To Two of the ten heaviest scientifically recorded earthquakes had their epicenter near the Greater Patagonian Trail (1960 Valdivia earthquake with magnitude 9.5 and 2010 Bio-Bio earthquake with magnitude 8.8). In the first 15 years of this century USGS lists more than 300 earthquakes with a magnitude of 5.0 or more in the area of the trail (area from -35°S to -45°S and -75°W to -70°W). Therefore don't be issuedtoo surpised if the ground below you starts to move. A earthquake may loose rocks and cause landslides and tsunamies. Therefore be cautious when selecting a place to camp. Avoid areas where scree and rubble indicates hazard zone. If you get hit by an earthquake while walking look up to to check the area above you for liberated material that comes towards you and seek shelter. If a heavy earthquake occurs while walking or camping next to a fjord or lake get on higher ground in case of an tsunami. Be aware that a landslide into a lake may cause a tsunami on a lake shore.
