This barren lava flow issued from a fissure vent on the SE flank of San Miguel in 1819. The flow traveled about 5 km and covered a broad area below the SE base of the volcano, extending down to 25 m above sea level. Emplacement of the lava flow necessitated the construction of a new road at the base of the volcano.
