Global Volcanism Program | Image GVP-07643

The dark-colored areas at the bottom of the photo are lava flows erupted from a SSE-flank vent of San Miguel in December 1855.  The larger dark area above it extending diagonally across the image is a cloud shadow.  The 1855 lava flows were erupted from a SSE-trending radial fissure and were the smallest flows erupted at San Miguel in historical time, extending only about a kilometer from the vent.
