BackgroundJumaytepeque is a small basaltic stratovolcano located NNE of the city of Cuilapa, north of the major NW-SE-trending Jalpatagua fault that cuts diagonally across SE Guatemala. The 1815-m-high volcano was constructed near the SE rim of the large Miocene Santa Rosa de Lima caldera. Jumaytepeque volcano is not overlain by a ca. 23,000-year-old tephra unit from nearby Ayarza caldera, and its erosionally unmodified form suggests that Holocene activity is possible (Reynolds 2007, pers. comm.). Two older cinder cones to the north are covered with Ayarza tephra.
