The advancement of humanitarian geophysics in Southeast Asia: a student-based approach A 2011 final report to the SEG Geoscientists Without Borders program Lee M. Liberty – Associate Research Professor Center for Geophysical Investigation of the Shallow Subsurface (CGISS)/Department of Geosciences Boise State University [email protected] and the team of instructors http://cgiss.boisestate.edu/gwb Executive Summary This report summarizes the operational activities of the 2011 geophysics field camp that Boise State University (BSU), in conjunction with Chiang Mai University (CMU), conducted through a Geoscientists Without Borders (GWB) SEG Foundation grant. Faculty, technicians, and students from seventeen participating institutions from eleven countries acquired, processed and interpreted geophysical data at three separate sites in Chiang Mai, Thailand. These field sites were selected to train participants in the use of a variety of geophysical methods to address groundwater, archaeology, and earthquake hazards problems. Many of the planning and initiation of this field camp mimicked the 2010 field program. The second annual Geoscientists Without Borders funded Southeast Asia geophysics field camp took place from 2-15 January, 2011 in Chiang Mai, Thailand with 38 student participants and 19 instructor/technicians at two field sites. Geophysical methods include electromagnetic, resistivity, seismic reflection, seismic refraction, seismic surface wave, gravity, magnetic and ground penetrating radar. This report is a summary of a week-long data acquisition session followed by a week-long data analysis session where seismic, ground penetrating radar, electrical, electromagnetic, gravity, and magnetic data were acquired, processed, and interpreted at the Mae Jo and Wiang Kum Kam sites near Chiang Mai, Thailand. Mae Jo is the site of a M5.1 earthquake in 2006. Geophysical surveys were conducted along rural roads and adjacent farm fields to identify geologic structures and faults related to the seismically active region. Wiang Kum Kam is the site of an abandoned city where buried walls, temples, and related structures are of important historical significance to Thailand. Geophysical surveys focused on identifying and characterizing the paleo Ping River and identifying buried walls and structures related to the 13th century city. The field work conducted at Wiang Kum Kam during the 2011 field camp was an extension of the 2010 geophysics field camp survey.
