USING SEISMIC METHODS TO DETERMINE VOLCANIC CRUSTAL DEPTH OF SAN MIGUEL

In the city of San Miguel, El Salvador there is a looming presence that must always be under watch. The San Miguel volcano near the city of San Miguel is an active Stratovolcano, which tend to have extremely explosive eruptions. The study of this volcanoes interior structure is of the utmost importance for the safety of the city. Using seismic methods and instruments that were strategically placed on the volcano between 2007-2008, as well as the data from the USGS (United States Geological Society), I plan to determine the crustal thickness of the volcano using the technique called Receiver Functions(A technique using seismic activity as an echo rebounding off the volcanic crust). Doing this and creating images of the crust we can determine what parts of the volcano will be susceptible to breakage or which will have explosive characteristics if and when the volcano erupts.
