Joule heating and pore pressure evolution, magmatic intrusions at continental rifts, and microseisms in Yellowstone Lake
The goal of this thesis is to investigate research topics related to geothermal resources. Chapter 1 introduces the thesis and motivates the need to study research topics in relevant geothermal environments, and develop new technologies to economically extract heat from these resources. In Chapter …

Quantifying hurricane wind speed with undersea sound
… also long been known that hurricanes generate microseisms in the 0.1 to 0.6 Hz frequency range through the non-linear interaction of ocean surface waves. Here we model microseisms generated by the spatially inhomogeneous waves of a hurricane with the non-linear wave equation where a …

Acoustic monitoring of hydraulic stimulation in granites
… of considerable study. Acoustic emissions, or microseisms, contribute greatly to these studies and have been employed on a wide range of topics in rock mechanic studies. At Colorado School of Mines, acoustic emission technology has been employed to monitor stimulation of cubic granite samples …

Fluid flow and sound generation at hydrothermal vent fields
… be attributed to ambient ocean noise sources of microseisms, distant shipping and weather, punctuated by local ships and biological sources. Water/rock interface waves of local origin, were detected which showed high pressure amplitudes near the seafloor and, decaying with vertical distance, …

Very low frequency seismo-acoustic noise below the sea floor (0.2-10 Hz)
… studies conclude that the primary source of microseisms is nonlinear interaction of surface gravity waves at the sea surface. Though this source relationship is generally accepted, the actual processes by which the wave generated acoustic noise in the water column couples and propagates to …

Microseismic observations in the Ceres-Tulbagh aftershock zone, Western Cape, South Africa, and their tectonic implications
… down to 12 km depth. The magnitude of the microseisms ranges from -2.2 < ML < 1.6 with a magnitude of completeness of Mc -1.5, and follow a Gutenberg-Richter distribution with a b -value of 0.9. The microseismic events occurred down to a depth of 15 km within a sub-vertical fault zone …

Microtremor recordings in Northern Mississippi: Evaluating site effect and correlating with wave climate
… within DF range, and it can be concluded that DF microseisms are strongly influenced by ocean activities. Therefore, the possible influence from ocean activities on the estimation of f0 and amplification factor using HVSR method is examined by correlating the HVSR@f0 to the ocean wave climate …

Analysis of seismo-acoustic emission from ice fracturing events during SIMI’94
In this thesis the analysis of natural ice events is carried out based on direct measurements of ice-borne seismo-acoustic waves generated by ice fracturing processes. A major reason for studying this phenomenon is that this acoustic emission is a significant contributor to Arctic ocean ambient …
