SEI2: Wide Area Wireless Networks for Geophysics

The first long term scientific deployment of the portable broadband seismic array is a part of MASE (Middle America Subduction Experiment) in collaboration with California Institute of Technology and Universidad Nacional Autnoma de Mexico (UNAM). We are mapping the subducted slab beneath Mexico and examining slow earthquakes which have been observed at this subduction zone, volcanic earthquakes and the propagation of seismic waves in Mexico City which was devastated in the 1985 Michoacan earthquake. We will compare our 50 instrument wireless array with the 50 instruments of a stand-alone array that has been installed by Caltech. The transect covered by all stations is 500 km long between Acapulco-Mexico City-Tampico
