First International Workshop on Acoustic Remote Sensing of Volcanoes

Held in Quito, Ecuador in conjuction with the Cities on Volcanoes 4 Conference

January 22, 2006

Introduction

The workshop presents volcano-acoustic remote sensing as a mature technology, with established measurement, analysis, and data dissemination procedures that can be incorporated into civil defense and aviation applications as well as into research programs. We present the basic physics of acoustic wave propagation in the atmosphere, summarize the state of the art in recording and data analysis techniques, and discuss applications using near- and far-field acoustic observations of diverse volcanic eruption styles. We also consider the interpretive tools needed to transform a raw acoustic data stream into useful products that may be used by civil defense authorities and the aviation industry.
