The modern volcanologist’s tool kit
It’s an exciting time to be a volcanologist, particularly if your specialty is volcano geodesy. Volcanology is in the midst of a revolution, and geodesy is helping to lead the way. Faster than ever before, new technologies and techniques are changing our understanding of how volcanoes work by revealing how they behave — before, during, and after eruption — in unprecedented detail. Capabilities that would have seemed far-fetched just a few decades ago — such as watching volcanoes deform from space, tracking the rise of a magma-filled dike in real time, or predicting eruptions accurately and early enough for people to move out of harm’s way without unduly disrupting their everyday lives — are fast becoming realities. I wrote this book because 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.

- 4.There are several measures of earthquake magnitude, including local magnitude M l. body-wave magnitude M b, surface-wave magnitude M s, and moment magnitude M w. Unless specified otherwise, all earthquake magnitudes in this book are local magnitudes M = M L, as originally defined by Richter (1935).Google Scholar
- 7.The Mercalli Intensity Scale is used to classify the intensity of an earthquake by examining its effects on people and structures. It was conceived by Italian volcanologist Giuseppe Mercalli in 1902, and was in general use before the Richter scale was developed by Charles Francis Richter and Beno Gutenberg in 1935. The form currently used in the U.S.A. is the Modified Mercalli (MM) Intensity Scale, which was developed in 1931 by American seismologists Harry Wood and Frank Neumann.Google Scholar
