Explosive Eruptions With Little Warning: Experimental Petrology and Volcano Monitoring Observations From the 2014 Eruption of Kelud, Indonesia

Geochemistry, Geophysics, Geosystems, Volume 20, Issue 8, Page 4218-4247, August 2019., 2019
Abstract Explosive eruptions that occur with little or no precursory unrest (less than a month) pose the greatest hazards from volcanoes to nearby populations. Here we focus on the preeruptive conditions for these explosive events, their triggers and how these eruptions evolve.

Identification of Variations in the Climatic Conditions of the Lerma‐Chapala‐Santiago Watershed by Comparative Analysis of Time Series

Advances in Meteorology, Volume 2018, Issue 1, 2018., 2018
The current study presents a method for automating the Köppen–Garcia climate classification using a GIS module. This method was then applied in a case study of the Lerma‐Chapala‐Santiago watershed to compare time series data on climate from 1960 to 1989, 1981 to 2010, and 1960 to 2010.

Multivariate Analysis, Mass Balance Techniques, and Statistical Tests as Tools in Igneous Petrology: Application to the Sierra de las Cruces Volcanic Range (Mexican Volcanic Belt)

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
Magmatic processes have usually been identified and evaluated using qualitative or semiquantitative geochemical or isotopic tools based on a restricted number of variables. However, a more complete and quantitative view could be reached applying multivariate analysis, mass balance techniques, and statistical tests.

Valley of Mexico site response from non‐reference site approach

Earthquake Spectra, Volume 41, Issue 2, Page 1029-1059, May 2025.
We present a model for Valley of Mexico site response that is referenced to a 30 m time‐averaged shear wave velocity (VS30) of 760 m/s. This reference condition ensures compatibility with regional ground motion models (GMM) for Central America and Mexico (CAM), which were developed from an expanded version of the NGA‐Subduction (NGA‐Sub) database as ...
