Turns out Chile has a ton of volcanoes.  In fact, there's about 2,000 of them dotted around the Andes, but the majority of them are dormant or extinct. Chile has the second largest volcano chain in the world, after Indonesia. According to an article on ChileCulture.org, "About 500 volcanoes are potentially active, 36 are currently active and 44 have erupted at least once since 1820". In addition, there have been 15 eruptions in the last 20 years. Other interesting facts The last eruption in Chile was of Calbuco Volcano in Puerto Varas on April 22, 2015 Here's a time lapse video ;-) ~ video ~ According to the Global Volcanism Program, the Chaiten volcano in the southern region of Chile erupted in 2009 - its most recent eruption prior to it was around the year 7420 BC +/- 72 years (what the heck?!) Most of the large volcanoes are stratovolcanoes There's also plenty of geysers, hot springs, and fumaroles  How Chile Warns its People I actually w...

Because Chile is so prone to seismic activity, their earthquake preparedness and preventative measures are some of the best in the world. Warning Systems Following the 8.8 earthquake of 2010 that claimed the lives of more than 500 people, Chile "implemented a new system that alerted residents by telephone, computers and television in real time". The system, compromised of a network of digital broadband seismic and ground motion stations, Global Navigation Satellite System (GNSS) stations, and GPS stations, allows Chile to capture accurate information for damage assessment and warnings. Chile has also recently experimented with a newer system the rest of the world may soon adopt, called G-FAST. The Seismological Society of America describes G-FAST as using "ground motion data measured by GNSS to estimate the magnitude and epicenter for large earthquakes". The implementation of this system could allow even more time for earthquake warning and evacuation in the fu...

Chile is located essentially at the convergence of the South American, Nazca, and Antarctic plates. The South American and Nazca plates converge at about 88 mm per year (one of the fastest rates in the world) making Chile an area highly vulnerable to earthquakes, tsunamis, volcanism, and landslides. Chile's earthquakes in particular tend to be very powerful, so powerful in fact that it boasts the location of the largest earthquake of the last 200 years - the 9.5 earthquake of 1960. The strength of these humongous earthquakes often causes large earthquakes and tsunamis to occur elsewhere. For example, the 1960 earthquake caused a tsunami that caused loss of life not only in Chile, but Japan, Hawaii, and the Philippines as well. Chile has encountered 13 major earthquakes in the last 30 years.
