San Miguel volcano, also known as Chaparrastique, is an active stratovolcano located in eastern El Salvador. It is characterised by a symmetrical cone rising to an elevation of 2,130 meters, making it one of the country’s most prominent landmarks. Composed primarily of basaltic andesite, San Miguel has a history of frequent eruptions, with at least 29 recorded events since the 16th century. These eruptions have typically involved the effusion of lava flows, strombolian activity, and the ejection of ash and tephra. The summit features a complex crater that has been significantly modified by repeated eruptive activity.

2016 Minor eruption with ash emissions and increased gas activity. No significant impact on surrounding communities.
2013 Significant eruption starting in December. Large ash plumes reaching several kilometers high, leading to evacuations and disruptions to air travel. Ashfall affected coffee plantations and caused respiratory problems.
1976 Eruption with lava flows reaching the base of the volcano and significant ashfall impacting local communities.
1964 Strombolian activity with lava fountains observed within the crater and ash plumes rising above the summit.
1944 Ash emissions and some lava flows reported. Limited information available on the extent of the impacts.
1878 Reports of lava flows, but details are scarce.
1787 Significant eruption with lava flows traveling several kilometers and widespread ashfall. Likely caused significant disruption to the region.
