Real-time, high-frequency gas measurements enable detection of subtle shifts in CO2 flux and gas ratios that may reflect magma ascent, pressurisation, and changes in conduit permeability. When integrated with seismicity and ground deformation data, these geochemical signals form a critical component of multi-parameter early-warning systems for forecasting ...
We’ve currently published a publication which comes back to a relationship between attenuation and velocity dispersion of body waves which replaces the measurement of the amplitude characteristics of seismic signals by a frequency dependent velocity function. The implementation of this method has previously shown to be difficult because of the very small levels of ...

Geological Characterization of the South Georgia Rift Basin for CO2 Storage. In 2010-11, Bay partnered with the University of South Carolina Research Foundation in the United States Department of Energy program studying the feasibility and suitability of using Jurassic/Triassic (J/TR) sediments of the South Georgia Rift Basin (SGR) for CO2 ...
Caplan-Auerbach has studied Lo'ihi since she was a graduate student in 1996, with more recent work at Kilauea, using data from seismic instruments placed on the submarine flanks of both volcanoes. ...
Over the next few months we’ll be analyzing the data collected during stimulation and working with the Department of Energy to move forward with the project. ...
Seismic reflection data from target depths of several hundred metres have been acquired and processed as an aid for lignite exploration in the Miocene Soma Basin, western Turkey. An environmentally–friendly approach was followed by acquiring the data with mini–vibroseisseismic source along crooked lines, using available mountain/forest and ...
We have two complete Vertek Hogentogler systems with 5T, 10T tension cones, conductivity module, seismic, pore pressure, and temp. We have had great success pushing through challenging soils throughout the United States. ...
As part of the geotechnical study, GeoView, Spotlight Geophysics and ATI Panamericana were tasked to provide seismic P-wave and S-wave velocity structure of the subsurface. The consortium collected seismic refraction and multi-channel analysis of surface waves (MASW) data along survey transects approximately 4 kilometers in length. ...
In support of their characterization efforts, GUPC requested that seismic geophysical data be acquired at four locations within the project area. ...
Because of the large contrast in both seismic velocity and electrical resistivity, the geophysical investigation was conducted using a combination of p-wave seismic refraction and electrical resistivity imaging (ERI). Both 2-dimensional and 3-dimensional data was collected at the site. A total of 2,300 ft of Seismic Refraction ...
Integration & Joint Interpretation of Passive Seismic Tomography, Gravity and MT Data The scope of this project was an integrated interpretation of the Passive Seismic Tomography, Gravity and Magnetotelluric data, acquired in the Delvina Gas field area in the context of the according geophysical surveys. Although the ...
These slides depicted visualizations of seismic data. During the stimulation process small micro-earthquakes (MEQs) are generated when natural fractures undergo shear failure, when fractures spontaneously close, or for a variety of other kinetic reasons. Using a micro-seismic array developers are able to monitor these events and determine at ...
Produced time-structure Maps via interpretation of Gulf Coast seismic reflection data while employed with Conoco, Inc. Produced time-structure Maps via interpretation of complex Overthrust Belt seismic reflection data for a graduate school project at the Colorado School of Mines. Coordinated the processing of complex trace ...
Passive Seismic Tomography Project Phase II Project Area: approximately 2000km2 Seismic Network: 76 stations Recording Period: 9 months Number of Seismic Events located/used: 276/263 The scope of this project, which followed a successful Phase I Passive Seismic Tomography survey in the same area, was to provide accurate and ...
So fast data are available over destroyed journeys in the case of seriousness. ...

Field investigations including seismic reflection, exploratory borings, piezometry, hydrogeochemical data, and contaminant spreading, as well as numerical modeling, collectively indicate that this feature apparently isolates contaminant discharges entering the shallow aquifer (MCA) from the perched zone from the rest of the shallow aquifer (SPA), and from the San ...
Seismic waves were generated and data were recorded at 5-foot station spacings. ...
New, very high-resolution (25 cm) seismic profiles have revealed the internal architecture of the infilling of a macrotidal bay, the Marennes-Oléron Bay, France. Within this geometry, a major seismic unconformity has been correlated with core data. This correlation provides evidence that the seismic unconformity corresponds to a ...
