The seismic array is part of the Middle America Subduction Experiment (MASE) partnered with Caltech and Universidad Nacional Aut��ónoma de M��éxico (UNAM). The goals are to map the subducted slab beneath Mexico; examine slow earthquakes observed at this subduction zone; examine volcanic earthquakes observed at this subduction zone; and study the propagation of seismic waves in Mexico City. This will require a line of about 100 stations from Acapulco to Tampico through Mexico City. 50 of the stations are equipped with temporary data-loggers and high-powered 802.11 wireless hardware and antennas. This poster describes the software to achieve an end-to-end autonomous seismic data collection system.
