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 ...

The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

In 1998, the SHIPS (Seismic Hazards Investigation in Puget Sound) program acquired seismic reflection data through Puget Sound as part of a large survey aimed at mapping the subsurface architecture to ...

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 ...

The Finnish Reflection Experiment (FIRE) dataset consists of seismic reflection data from 2,104 km of common mid-point (CMP) lines. The four FIRE transects cross-cut several geologically and ...

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 ...
