The catastrophic 1902 eruption of Santa María excavated a massive 1.5-km-wide crater in the SW flank of the volcano.  The upper part of the crater headwall, which extends nearly to the summit of Santa María, is seen in this aerial photo from the SW.  Guatemala's second largest city, Quetzaltenango, lies in the basin visible at the left behind the volcano 10 km to the NNE.  The dacitic 1902 eruption took place after a long period of quiescence that followed construction of the basaltic-andesite volcano. Photo by Sam Bonis (Instituto Geográfico Nacional).
