Gas Migration: Events Preceding Earthquakes

This breakthrough new book may help save countless lives and avoid enormous losses. It presents a methodology for using gas migration to predict earthquakes and explosive gas buildup. Using rigorous scientific investigation and documented worldwide case histories, this remarkable book presents compelling evidence showing that changes in gas rates, composition, and migration accompany the tectronic events preceding earthquakes and their associated seismic events, such as volcanoes and tsunamis. Because these gas parameters are detectable and measurable, they provide an early warning of seismic activity.

Gas Migration is the first book to accumulate, analyze and apply the interdisciplinary knowledge on gas migration and detail its connection to tectronic, seismic, and geologic phenomena. It combines geological, geochemical, geophysical, seismological, and petroleum engineering insights to demonstrate how gas migration and its associated phenomena can be used in earthquake and environmental geohazard identification and prediction. Topics include-

· Tectonics and Earthquakes
· Gas Migration at Plate Boundaries
· Surface Soil-Gas Surveys
· Faults and Petroleum Reservoirs
· Earthquake Precursors
· Whispering Gases
· Paths and Mechanics of Gas Migration
· Subsidence, Gas Migration, and Seismic Activity
· And much more

With this information, environmental specialists, civil engineers, petroleum geologists, seismologists, and urban planners now have a new and powerful conceptual basis and tool for understanding and perhaps even predicting gas explosions and earthquakes.
