Lava flows armor the western flank of Arenal volcano in Costa Rica. All the flows seen here were emplaced during a long-term eruption that began in 1968. This 1983 aerial view from the SSW shows many individual lava-flow lobes. Prominent flow levees are visible, particularly on the flows at the right. Lava flows from the current Arenal eruption extend 4 km to the NW and about 2.5 km to the SW.
