Seismology in the City
Seismology in the City Temporary seismometer array in New York City to record ambient noise. Introduction We usually think of noise as a bad thing. Noise during the quiet part of an orchestra performance is annoying and ruins the music. Static on the telephone (a type of noise) makes it difficult to hear what your friend is saying. And when you...
Twenty years have elasped since the first issue of Earthquakes & Volcanoes. Apart from the remarkable increases in the number of scientists actively enagaged in earth sciences, what are the outstanding achievements during the past 20 years in the field of engineering seismology, which is my own speciality?
Seismology in Chile
The Department of Geology and Geophysics, which is under the faculties of Mathematics and Physical Sciences of the University of Chile, is the organization that is responsible for the Seismological Service of Chile and for installing,operating, and maintaining the seismological stations as well as all the strong-motion stations in Chile.
A fundamental goal of volcano seismology is to understand active magmatic systems, to characterize the configuration of such systems, and to determine the extent and evolution of source regions of magmatic energy. Such understanding is critical to our assessment of eruptive behavior and its hazardous impacts. With the emergence of portable...
Rotational seismology is an emerging study of all aspects of rotational motions induced by earthquakes, explosions, and ambient vibrations. It is of interest to several disciplines, including seismology, earthquake engineering, geodesy, and earth-based detection of Einstein’s gravitation waves.Rotational effects of seismic waves, together with...
Twenty years ago, politicians, concerned a the slow progress of negotiations to stop nuclear weapons testing, described the state of seismology as being in the equivalent of the Stone Age. this assessment spurred the beginning of research and development at the Atomic Weapons Research Establishment near the village of Aldermaston, England. the...

Seismology in Mexico
Mexico is situated at the intersection of four major crustal Plates: the Americas Plate, the Pacific Plate, the Caribbean Plate, and the Cocos Plate. The interaction of these four plates is very complex. The pattern of earthquake risk is, therefore, among the most complicated in the world. The average release of seismic energy each is 55x1021 ergs...
Jesuits in seismology
Jesuits have been involved with scientific endeavors since the 16th century, although their association with seismology is more recent. What impelled Jesuit priests to also become seismologists is am matter of conjecture. Certainly the migration of missionaries to various parts of the world must have resulted in queries to their fellow Jesuits in...
