Borehole observations of continuous strain and fluid pressure,ormous strain prior to and during eruption. Global Positioning System (GPS) observations can in principle be used to determine strain by taking the difference between two nearby observations and dividing by the distance between them. Two GPS stations 1 km apart, each providing displacement informati

Hydrothermal systems and volcano geochemistry,hapter will examine less obvious roles that hydrothermal processes might play in volcanic deformation. Emphasis will be placed on the effect that the transition from brittle to plastic behavior of rocks is likely to have on magma degassing and hydrothermal processes, and on the likely chemical varia

Challenges and opportunities for the 21st century, tools have been used to infer what might be happening beneath a few well studied volcanoes, and explored some emerging links between geodesy and other disciplines in volcanology. In this final chapter, I take a step back to consider some basic questions about the current state of volcano geodesy an

,The modern volcanologist’s tool kit, I wanted to share my excitement over these advances, not only with serious students of volcanology but also with anyone who has admired the beauty of a snow-capped volcano or marveled at the raw power of a volcanic eruption.

Continuous monitoring with , sensors,ar a hazardous volcano, potentially in harm’s way; and (2) repeated surveys cannot always keep pace with a rapidly evolving crisis, especially at night or during bad weather. Therefore, it is desirable to supplement periodic geodetic surveys with carefully sited continuous sensors that provide a steady stream of data in real time for analysis.

Borehole observations of continuous strain and fluid pressure,on accurate to the nearest millimeter, could detect strain as small as 2 mm km., or 2 × 10.. It is possible, however, to measure strains at least three orders of magnitude smaller using borehole strainmeters. In fact, it is even possible to measure strains as small as 10. using observations of groundwater levels in boreholes.
