Three-dimensional seismic-reflection imaging is not new. The petroleum industry has been utilizing this tool to characterize the complex geometries of the subsurface for nearly two decades. Science ...

Geophysics is the application of the methods and techniques of physics in the study of the Earth. It differs from Geology in that a geologist studies rocks and structures, which can be seen, while a ...

Older strata may yield direct hydrocarbon indicators (DHIs) in environments typically thought unlikely to contain them. DHIs are features in seismic reflection data attributed to accumulations of oil ...

Midway between the earthquake and opposing seismometer the seismic energy reflects in a circular pattern around the top of the inner core. Image may only be used with appropriate caption and credit.
