With this unique book, you can broaden your knowledge about intriguing natural occurrences like earthquakes, sunspots, and lightning strikes by building and using inexpensive, yet sensitive and accurate, devices for monitoring seismic activity, atmospheric anomalies, and solar disturbances. By combining the more than 40 projects included inside, you can construct your own complete scientific monitoring station! You'd pay thousands for this type of hard-to-find equipment at commercial outlets, yet these devices can be made from readily available parts at an average cost of just $25. Each skill-building project has been field-tested by author Gary G. Giusti, a National Weather Service spotter and longtime student of earthquakes and weather phenomena. Giusti provides a handy parts list and complete instructions for all projects.

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 moreWith 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.

This text is aimed at technicians, hobbyists, and students and provides complete circuit diagrams and building instructions for a wide range of creative sleuthing applications. The designs are fully tested and proven effective in real-world alarm, sensor, and security equipment.

This new guide describes the application of spatial technology to improve disaster risk management (DRM) within the aquaculture sector. DRM requires interrelated actions and activities to ensure early warning, prevention, preparedness, response and recovery for a wide range of natural, technological and complex disasters that can impact aquaculture operations and livelihoods. Spatial technology refers to systems and tools that acquire, manage and analyse data that have geographic context. Some of the technologies include satellite remote sensing, aerial surveys, global positioning systems, geographic information systems, information and communication technology and other data gathering sensors used, for instance, in meteorology. Spatial technology supports activities across all phases of the DRM cycle and its rapid development provides enhanced opportunities to support DRM within the aquaculture sector. This guide is organized in two parts. Part one is the “guidance”; it is the main body of the document and describes the processes and steps for the use of spatial technology within DRM for aquaculture. Part two includes selected country case studies from Bangladesh, the Gulf of Mexico and the Caribbean, and Indonesia to illustrate the application of spatial technology in DRM for aquaculture at the national level within local contexts. Best practices at the farm and area management levels, supported by spatial technology, reduce volatility and risks and thus facilitate investment. Countries that would like aquaculture to grow sustainably and reliably are encouraged to use this guide in order to support spatial planning approaches and protect responsible investors. A separate summary version accompanies this publication.
