NASA Earth Observatory




San Miguel (also known as Chaparrastique) is one of the most active volcanoes in El Salvador. On January 12, 2016, Moderate Resolution Imaging Spectroradiometer (MODIS) sensors on NASA’s Aqua and Terra satellites acquired these natural-color images of ash streaming from the mountain. Terra captured the upper image at 10:35 a.m. local time (16:35 Universal Time); Aqua captured the lower image at 1:35 p.m. local time (19:35 Universal Time). Winds transported the volcanic plume to the southwest.
