Application of Seismic Refraction Tomography to Karst Cavities
For three years we have used synthetic and field data to investigate the effectiveness of commercial refraction tomography codes on both simple and complex subsurface velocity structures, with the ultimate goal of determining the suitability of the method for karst problems. The results of these studies indicate that refraction tomography is able to resolve karst features under some conditions....
متن کاملTwo Dimensional Filtering of Seismic Data
High resolution surveys with single shots and geophones record wide spectral bands of reflectionenergy but the signal quality is often unacceptable due to a high content of random and organized noise. Coherency filtering of such data may provide misleading sections reflecting the bias of the processor. We have found that two-dimensional filtering with short operators handles this problematic si...
متن کاملDuctile Gap between the Wenchuan and Lushan Earthquakes Revealed from the Two-dimensional Pg Seismic Tomography
A high-resolution two-dimensional Pg-wave velocity model is obtained for the upper crust around the epicenters of the April 20, 2013 Ms7.0 Lushan earthquake and the May 12, 2008 Ms8.0 Wenchuan earthquake, China. The tomographic inversion uses 47235 Pg arrival times from 6812 aftershocks recorded by 61 stations around the Lushan and Wenchuan earthquakes. Across the front Longmenshan fault near t...
متن کاملHIGH RESOLUTION SEISMIc REFRAcTION TOMOGRAPHY FOR DETERMINING DEPTH OF BLAST INDUcED DAMAGE IN A MINE WALL
High resolution seismic refraction tomography has proved to be a useful tool to effectively estimate depth of blast induced damage in a mine face. Excavation blast damage can be as shallow as 1 to 2m and requires resolution at a fraction of a meter for effective imaging. We used an accelerometer with flat frequency response to 1000Hz to record data at spacings of approximately 0.25 to 0.5m alon...
متن کاملLocation of Sinkhole Extension by Seismic Refraction Tomography and GPR Methods
In 2008 a stream flow created a sinkhole near Park City, Utah, creating an irregular-shaped depression in the alluvium about 22 m long, 10 m wide and 6 m deep. The entire discharge of a nearby creek flowed into the sinkhole increasing the size of the sinkhole. A total of 10 GPR and 4 seismic refraction profiles were conducted to find lateral and vertical extensions of this sinkhole. Interpretat...
