Global Volcanism Program | Image GVP-07709
The campus of the Universidad Nacional Autónoma de México (UNAM), the National University of México, overlies a 1,600-year-old lava flow from the Xitle scoria cone in the Chichinautzin volcanic field. Basaltic lava from Xitle is exposed in the foreground between buildings of the departments of geology and geophysics. Volcanologists and seismologists from the university conduct research on Mexican volcanoes and are involved in monitoring of ongoing activity.
