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 this was as the article says, plumbing that ran underneath the volcanoes all across the country. Chile also has a large number of sinkholes that pop up along the country due to the vast amounts of mining done in the country, in a recent article, a large sinkhole opened up in a rural area that completely swallowed up an entire house.
Thanks for reading, I will see you all next week.
