Land Cover Change in Post-War/Post-Earthquake El Salvador

I am interested in looking at images of El Salvador.  One would be post-war circa 1992, when the 12-year civil war ended and another would be post-earthquakes, 2002, after two major earthquakes ravaged the country.  I would like to look for changes in land use and to see if it is possible to detect which changes are due to war and which are caused by earthquakes.

I will also be continuing my OEFS project, looking at shrimp farming in Ecuador.
