Meteorite craters – Research – Perak – Lenggong – Bukit Bunuh "This monograph illustrates how geophysical methods can be used to explore the subsurface of our Earth. Geophysical method (magnetic, gravity, seismic refraction and 2D resistivity) and geotechnical method (boring) were applied to study the characterization of the subsurface and to prove that the study area was a meteorite impact area. The study continues with the geophysical data acquisition and processing techniques together with integration of the results (including borehole) for better interpretation. A thorough integration of the archaeological data with geophysical data successfully delineates the history of the area investigated ... compiled accordingly to capture the readers' interest especially to students in archaeology, engineering, environmental, geology and geophysics courses"
