Week 8: Soil subsidence in Chile This weeks blog will talk about Chile's ground and how susceptible it is to subside. Hello all! this week's blog is very interesting, it's all about soil Subsidence. Soil subsidence is when the surface level of the soil in an area changes in elevation. This is caused by both natural and man-made effects such as mining, natural compaction, hydrocompaction, sinkholes, and permafrost. The country of Chile, like most, deals with this to some level. Chile is known for its powerful earthquakes. In 2010, one earthquake was so powerful that it caused several of the Chilian volcanos to sink. "shows that five volcanic regions within 248 miles of the 8.8-scale earthquake in Maule, Chile, sank up to 6 inches into the ground after the earthquake, almost instantly. This process, called subsidence, has never been seen on this scale in volcanic regions and could lead to insights about the “plumbing systems” underneath volcanoes" The cause of t...

Week 5: Volcanic Activity of Chile This week's blog will be about discussing Chile's Volcanic history both past and present. Hello all, I am not really sure why I start my blogs with this considering there are a solid 2 or 3 people who read this weekly, but regardless I am happy you are here! Chile is in what is known as the Ring of Fire, which is a figurative ring that runs around the pacific ocean that is characterized by a line of active volcanos and frequent earthquakes. Chile's entire coastline is in the Ring of Fire, and the country has a total of almost 2000 Volcanos mixed in with the Andes mountain range which runs along the spine of the country. Not all of those 2000 Volcanos are active, according to Volcanos of Chile, they say "About 500 volcanoes are potentially active, 36 are currently active and 44 have erupted at least once since 1820. In the last 20 years, there have been 15 volcanic eruptions". Comparatively, Chile is pretty active when it come...
