AbstrakIdentification of shallow subsurface structures on geothermal field of ie jue, seulawah agam using
seismic refraction method
abstract
subsurface geological structures in geothermal area are very fundamental to know before the geothermal field is exploited. map of the subsurface will provide information about physical condition distribution of geothermal field such as the presence of fractures / fault, lithology and other critical elements of a geothermal system. therefore, to determine the geothermal subsurface structures of seulawah agam then we conducted a research using seismic refraction method in geothermal field of ie jue, aceh besar regency. seismic refraction method was used to identify shallow subsurface structures based on compressional wave velocity value (compressional p-wave velocity, vp). the data of p-wave velocity were acquired and recorded using pasi 16s24-p seismograph where the seismic wave being triggered by an impact of sledge hammer and detected by arrays
