Lake Ilopango history and eruptions.

Ilopango caldera is a result of massive volcanic eruptions that occurred thousands of years ago. The outburst that occurred between 410 and 535 AD desolated Mayan cities in the area.

The Smithsonian channel produced this video, it describes the eruption of Ilopango’s Lake and the effects it had on the world’s climate at that time.



The eruptions of 1879 to 1880 formed the group of islands located in the center of the lake, these islands are called “burnt islands.” They serve as a reminder of the history this lake carries with it.

Additionally, in 2016, researches from the UK published a report saying that they found evidence that a pool of magma is building up beneath Ilopango’s lake. Of course, this evidence suggests that San Salvador, the capital might be at risk for a future volcanic eruption. It’s an interesting read, click here to read the research’s article.

El Salvador’s Lake Ilopango, near the capital city of San Salvador, is known for boating, diving and the rugged, scenic beauty of its 100 meter-tall cliffs — the lip of the caldera that holds the lake. However, 1,500 years ago, it may have been the site of one of the most horrific natural disasters in the world. It may also be the long-sought cause of the extreme climate cooling and crop failures of A.D. 535-536.
