Examples of seismic waveform data collected by the Transportable Array. The upper left record section shows recordings of an earthquake in Peru on February 24, 2007. Vertical component seismograms from 24 stations and three-component data from one station are shown. The bandpass filter used in this record section (0.1–0.001 sec) emphasizes the teleseismic surface waves, but also shows the initial P wave at approximately 5 minutes on the time scale. The number of stations shown here is less than 10% of the stations available for this event and only 6% of the total number of stations eventually to be deployed in the 400-element Transportable Array.
