Geology and eruptive history of some active volcanoes of México
Most of the largest volcanoes in México are located at the frontal part of the Trans-Mexican Volcanic Belt and in other isolated areas. This chapter considers some of these volcanoes: Colima, Nevado de Toluca, Popocatépetl, Pico de Orizaba (Citlaltépetl), and Tacaná. El Chichón volcano is also considered within this group because of its catastrophic eruption in 1982. The volcanic edifi ce of th...
متن کاملGlobal observation of vertical-CLVD earthquakes at active volcanoes
[1] Some of the largest and most anomalous volcanic earthquakes have non-double-couple focal mechanisms. Here, we investigate the link between volcanic unrest and the occurrence of non-double-couple earthquakes with dominant vertical tension or pressure axes, known as vertical compensated-linear-vector-dipole (vertical-CLVD) earthquakes. We determine focal mechanisms for 313 target earthquakes ...
متن کاملOptimal Wavelengths for Studying Thermal Emission from Active Volcanoes
Introduction: Our goal is to identify the optimal wavelengths for studying volcanic activity on Io. While better temporal, spatial, and spectral resolution is always desired, practical limitations lead one to limit both the wavelength range and spectral resolution of an observation. Our primary motivation is to assist the development of future spacecraft observations, but these results are also...
متن کاملDetermining the Stress Field in Active Volcanoes Using Focal Mechanisms
Stress inversion of seismological datasets became an essential tool to retrieve the stress field of active tectonics and volcanic areas. In particular, in volcanic areas, it is able to put constrains on volcano-tectonics and in general in a better understanding of the volcano dynamics. During the last decades, a wide range of stress inversion techniques has been proposed, some of them specifica...
متن کاملPhysical mechanisms for vertical-CLVD earthquakes at active volcanoes
[1] Many volcanic earthquakes large enough to be detected globally have anomalous focal mechanisms and frequency content. In a previous study, we examined the relationship between active volcanism and the occurrence of a specific type of shallow, non-double-couple earthquake. We identified 101 earthquakes with vertical compensated-linear-vector-dipole (vertical-CLVD) focal mechanisms that took ...
