Volcanoes are plentiful in this tiny country (8k sq mi) and volcanic activity makes for fertile soil—and dilemmas. Attracted by the ability to grow good crops, along with the cooler temperatures that come with higher altitude, people often risk volcano hazards. (Wikipedia lists 22 volcanoes in E.S.) Here are a few of them:
Lake Ilopango. Elevation 1476 / 450 meters. This lake fills another beautiful volcanic caldera. The caldera collapsed in the 5th century AD, which produced widespread pyroclastic flows (translation: fast-moving flows which can reach 450 mph) and devastated Mayan cities. This eruption was rated a 6 out of 7 on the (VEI) Volcanic Explosivity Index (the amount of tefra, the stuff volcanoes spit out - technical definition I know... was 20 times as much as the 1980 eruption of Mount St. Helens). |
