Mapping demonstrates that Santa Maria’s volume is subequal to Santiaguito’s, if we count the 1902 eruption as part of Santiaguito. It also shows that Santiaguito has become increasingly dominated by exogenous lava flows, and has shifted its extrusion from the El Brujo vent back to Caliente since 1975.
