Abstract We use seismic refraction data to investigate the firn structure across a suture zone on Amery Ice Shelf, East Antarctica, and possible role of glacier dynamics in evolution. In downstream direction, reveal decreasing compressional-wave velocities increasing penetration depth propagating wave layer, consistent with $\sim$ 1 m thickening every 6 km. The boundary between Lambert Glacier ...

Seismic refraction profiles recorded layer. Crustal subsidence and periodic basaltic along the eastern Snake River Plain (ESRP) in southeastern Idaho during the 1978 YellowstoneSnake River Plain cooperative seismic profiling experiment are interpreted to infer the crustal velocity and attenuation (Q-i) structure of the ESRP. Travel-time and synthetic seismogram modeling of a 250 km reversed ref...

geological conditions of tabriz, a growing city in nw-iran, are strongly influenced by north tabriz fault (ntf). north tabriz fault is a major seismogenic fault in nw-iran. so, for a correct seismic microzonation, shear wave velocity (vs) structure in different part of city should be determined. but urban conditions, such as ambient noise due to cultural activity, restrict the general applicati...

Abstract The objective of this study was to identify the lithological layer around lake body determine ability reservoir structure withstand surrounding seepage water. This research conducted using MAE X820S seismic instrument, carried out on a 46-meter-long track and 24 geophones. Seismic refraction processing is done by picking at first break in each trace. From results, distance time paramet...
