Global Volcanism Program | Image GVP-07613
A lava flow field on the SW flank of Izalco is seen here from its summit. Levees define distinct flows of the lava field, which extends up to about 7 km from the summit. Most of the flows seen here were emplaced prior to 1954. Gas rises from fumaroles near the summit.
