===Earthquakes===

Two of the ten heaviest earthquakes in the 20th and 21st century had their epicentre near the Greater Patagonian Trail. The 1960 Valdivia earthquake had a magnitude of 9.5 and the 2010 Bio-Bio earthquake had magnitude of 8.8. In the first 15 years of this century more than 300 earthquakes with a magnitude of 5.0 or more occurred in the area of the trail (data retrieved from USGS for the area from -35°S to -45°S and -75°W to -70°W, the large majority are aftershocks of the major Bio-Bio earthquake in 2010). Therefore don't be too surprised if the ground below you starts to move.

An earthquake may lose rocks, trigger landslides and cause tsunamis. Therefore be cautious when selecting your place to camp. Avoid pitching your tent in areas where scree and rubble indicates a hazard zone below rocks and cliffs. If you get hit by an earthquake while walking look up 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 a lake get on higher ground in case of a tsunami. Be aware that a landslide into a lake may cause a tsunami on a lake shore.
