An explosion at El Salvador's San Miguel (also known as Chaparrastique) Volcano lofted ash more than 71 kilometers (44 miles) downwind on December 29, 2013. Volcanologist Francisco Barahona, quoted by, suggested that the blast was caused by the interaction of water and hot magma within the volcano. The paper also reported that the eruption subsided within 24 hours. Additional satellite imagery from December 30 showed that San Miguel was quiet.
