D'Appolonia's staff includes professionals with advanced degrees and extensive experience in the geological and related sciences. We draw upon this expertise for our projects requiring: Geologic mapping and hazards analysis Geophysical surveys (seismic reflection and refraction, radar, sonar, magnetic, electrical, electromagnetic and gravity) Seismic hazard analysis and establishment of seismic design criteria An understanding of subsurface conditions related to geologic structure, chemical alteration, depositional environment, moisture changes, previous mining and natural voids Geology/Geophysics/Seismology Projects: Landfill Siting and Engineering Dynamic Slope Stability Environmental Research - 3D Ground Penetrating Radar (GPR) High Resolution S-Wave Reflection Survey for Hydrogeological Investigations Expedited Site Characterization (ESC) Geophysical Site Reconnaissance for Subsurface Sampling, Testing, and Instrumentation

Petroleum and gas companies use seismic reflection as the main method to prepare geologic cross sections and target deep production wells. The method has seen relatively little application as a tool for ground water studies, however, because of the difficulty in achieving sufficiently high shallow resolution. D'Appolonia has actively researched improving the resolution of this technique since we first started to characterize shallow coal seams in the 1970's. Most recently our staff has been responsible for research conducted in association with Bay Geophysical Associates on behalf of Argonne National Laboratory to improve the technique using S-waves, rather than conventional P-waves. The use of S-waves offers the possibility to substantially increase resolution over a conventional P-wave survey under commonly encountered subsurface conditions. In hard rock, the S-wave velocity is usually about half of the P-wave velocity, but the predominant frequency is also about half, implying that the wavelength in the ground for both waves is similar and S-waves will not increase resolution. In a soil environment, however, S-waves can be several times slower than P-waves and have a similar frequency content, implying that S-waves can substantially increase resolution.

34. SEISMOLOGY AND GEOLOGY Chapter 03. seismology geology. Surely if the Earth was hollow then seismologistswould have discovered it by now? This was the question I had on my mind. http://www.greatdreams.com/hpch03.htm

Surely if the Earth was hollow then seismologists would have discovered it by now? This was the question I had on my mind. Unless perhaps they were misinterpreting the seismic data somehow. Could that possibly be the case? Could it therefore be that seismologists have indeed discovered a hollow planet without realising it? I think so. The Outer Core of the Earth is thought to be a liquid because certain types of seismic waves can not pass through it. This is our first indication that perhaps there is a cavity. That so-called liquid core might actually be a cavity. There is one problem with this hollow planet idea and that is that certain seismic waves actually travel through the Earth's Inner Core. Closer examination of this resulted in me discovering that the waves which pass through the Inner Core actually travel exceptionally slowly. Could this be because they are actually refracted so that they are travelling around the cavity rather than through the core? Could it be that beyond a certain point density again decreases thereby refracting seismic waves around a cavity? There is a shadow area which occurs 7,000 miles from earthquake epicentres. This shadow area can be easily explained if we assume that a hollow shell's density increases up to a point and thereafter decreases again. This will cause seismic waves to be split with some being refracted back up to the surface while others are refracted around a cavity. This would result in the exact characteristics seen in the shadow area.
