text: Windblown ash obscures soldiers searching the town of El Naranjo, 7.5 km south of the crater, a few days after the end of the eruption. Among the several thousand deaths caused by the eruption were one geologist and 32 soldiers sent to the village of Francisco León, ~ 6 km SW of the summit, after the March 28-29 explosion. The pyroclastic flow that traveled through Francisco León left only a thin deposit, but of the structures in the village, only one wall of the church, parallel to the direction of the pyroclastic flow's movement, remained standing.
