In this paper, we briefly summarize an aeromagnetic survey over a large stratovolcano (Popocatepetl) and surrounding volcanic terrain in central Mexico to show the potential that recent improvements in these methods have in studying active volcanoes.

After a decades-long period of quiescence, the Popocatepetl volcano reawakened in 1994. Background seismicity showed a two-fold increase in October 1994. This was followed on 21 December by a swarm of volcano-tectonic events and tremors accompanying a large ash plume.

Popocatepetl is an andesitic stratovolcano (Figure 1) in the central sector of the Plio-Quaternary Trans-Mexican volcanic belt (TMVB)—a continental arc associated with...
