Abstract
Electrical resistivity and a non-traditional seismic investigation technique were applied in<br>support of an archaeological investigation of a Pre-Columbian settlement in eastern Honduras. Field<br>studies were scheduled to be completed within a three-week window, so rapid response was critical to<br>the project. Electrical resistivity measurements were conducted in the profiling mode, using Wenner and<br>Lee configurations, at electrode spacings of 2 and 4 m. Seismic measurements were performed using the<br>SASW method, which is a surface-based technique using Rayleigh-type surface waves. Numerous<br>shallow anomalies were identified. Excavations revealed stone pavements, a carved stone, and a<br>human burial. Deeper anomalies prompted excavations which revealed a thick area1 fill above the<br>archaeologically sterile alluvium.
