Spatial, Temporal, and Dynamic Behavior of Different Entropies in Seismic Activity: The February 2023 Earthquakes in Türkiye and Syria Open

Denisse Pastén, Eugenio E. Vogel, Gonzalo Saravia, A. Posadas · 2025

Türkiye and Syria were hit by two powerful earthquakes on 6 February 2023. A 7.5 magnitude earthquake, soon followed by a second 7.4 magnitude seism, devastated the area. The present study compares three different entropies using data from…

2021 Alaska earthquake: entropy approach to its precursors and aftershock regimes Open

Eugenio E. Vogel, Denisse Pastén, Gonzalo Saravia, Michel Aguilera, A. Posadas · 2024

We have conducted an entropy analysis in Alaska, a seismic-rich region in a subduction zone that exhibits a nontrivial behavior: the subduction arc alters the seismic activity from the eastern zone to the western zone, demonstrating a decr…

2021 Alaska Earthquake: entropy approach to its precursors and aftershock regimes Open

Eugenio E. Vogel, Denisse Pastén, Gonzalo Saravia, Michel Aguilera, A. Posadas · 2024

For the first time, an entropy analysis has been made in Alaska, a seismic-rich region located in a subduction zone that shows a nontrivial behavior: the subduction arc changes the seismic activity from the eastern zone to the western zone…

Tsallis Entropy and Mutability to Characterize Seismic Sequences: The Case of 2007–2014 Northern Chile Earthquakes Open

Denisse Pastén, Eugenio E. Vogel, Gonzalo Saravia, A. Posadas, Oscar Sotolongo-Costa · 2023

Seismic data have improved in quality and quantity over the past few decades, enabling better statistical analysis. Statistical physics has proposed new ways to deal with these data to focus the attention on specific matters. The present p…

Earthquake hazard characterization by using entropy: application to northern Chilean earthquakes Open

A. Posadas, Denisse Pastén, Eugenio E. Vogel, Gonzalo Saravia · 2023

The mechanical description of the seismic cycle has an energetic analogy in terms of statistical physics and the second law of thermodynamics. In this context, an earthquake can be considered a phase transition, where continuous reorganiza…

Information theory and earthquakes: Depth propagation seismicity in northern Chile Open

Denisse Pastén, Gonzalo Saravia, Eugenio E. Vogel, A. Posadas · 2022

Mutability is an information theory tool intended to characterize sequences of non-linear phenomena (e.g., earthquakes). In this study, we used mutability to identify and analyze the depth propagation of seismicity in northern Chile. Durin…

Non-extensive entropy and fragment–asperity interaction model for earthquakes Open

A. Posadas, Oscar Sotolongo-Costa · 2022

In this study, we developed a fragment–asperity interaction model for earthquakes. Based on Tsallis entropy, this model can provide mathematical expression for the non-extensive entropy of fragments and asperities in the gouge area. From a…

Preservation of the Iberian Tethys paleomargin beneath the eastern Betic mountain range Open

Earthquakes and entropy: Characterization of occurrence of earthquakes in southern Spain and Alboran Sea Open

A. Posadas, J. Morales, A. Posadas-Garzon · 2021

We propose the use of entropy, H, as an indicator of the equilibrium state of a seismically active region (seismic system). The relationship between an increase in H and the occurrence of a great earthquake in a study area can be predicted…
