Is the Number of Foreshocks Underestimated? The Role of Declustering Symmetry
Herbian Hokky Prabowo, Eugenio Lippiello, Sebastian Hainzl +1
The physical origin of foreshocks remains one of the major unresolved problems in statistical seismology. In bottom-up (BU) triggering models, foreshocks are interpreted as ordinar…
Finite-Horizon Triggering Cores of Earthquake Sequences
Didier Sornette, Giuseppe Petrillo
Models of triggered seismicity commonly aggregate the contributions of all past earthquakes into a total predicted rate. This aggregation does not distinguish a forecast dominated…
Directed Cascades Generate New Critical Universality Classes
Didier Sornette, Eugenio Lippiello, Giuseppe Petrillo
Spectrally stable cascades can undergo enormous transient growth before eventually dying out. We show that this amplification is controlled by the directed architecture of the inte…
A Multiscaling Fingerprint of Earthquake Diffusion in Seismic Swarms
Cataldo Godano, Giuseppe Petrillo
Seismic swarms are commonly associated with fluid migration and other transient processes, yet their spatial migration remains difficult to quantify using conventional diffusion mo…
Anomalous Critical Behavior of Driven Disordered Systems Beyond the Overdamped Limit
Giuseppe Petrillo, Eduardo Jagla, Eugenio Lippiello +1
We investigate the role of relaxation mechanisms in the driven response of elastic disordered interfaces in finite dimensions, focusing on the interplay between dimensionality and…
Improve the estimate of the b-value in regional catalogs by means of the the b-more positive method
Eugenio Lippiello, Cataldo Godano, Giuseppe Petrillo
The b-value, which controls the slope of the frequency-magnitude distribution of earthquakes, is a critical parameter in seismic forecasting. However, accurately measuring the true…
How Ground Deformation Influences Earthquake Occurrence During the Ongoing Unrest at Campi Flegrei (2005-Present)
Cataldo Godano, Vincenzo Convertito, Anna Tramelli +1
We investigate the relationship between the cumulative number of earthquakes and ground uplift at the Campi Flegrei caldera (South Italy) during the ongoing unrest (2005-present).…
Evaluating the incompleteness magnitude using an unbiased estimate of the value
Cataldo Godano, Giuseppe Petrillo, Eugenio Lippiello
The evaluation of the value of the Gutenberg-Richter (GR) law, for a sample composed of earthquakes, presents a systematic positive bias which is proportional to …
Verifying the magnitude dependence in earthquake occurrence
Giuseppe Petrillo, Jiancang Zhuang
The existence of magnitude dependence in earthquake triggering has been reported. Such a correlation is linked to the issue of seismic predictability and remains under intense deba…
b-more-incomplete and b-more positive: Insights on A Robust Estimator of Magnitude Distribution
Eugenio Lippiello, Giuseppe Petrillo
The -value in earthquake magnitude-frequency distribution quantifies the relative frequency of large versus small earthquakes. Monitoring its evolution could provide fundamental…
Assessing the predicting power of GPS data for aftershocks forecasting
Vincenzo Maria Schimmenti, Giuseppe Petrillo, Alberto Rosso +1
We present a machine learning approach for the aftershock forecasting of Japanese earthquake catalogue from 2015 to 2019. Our method takes as sole input the ground surface deformat…
Including stress relaxation in point-process model for seismic occurrence
Giuseppe Petrillo, Jiancang Zhuang, Eugenio Lippiello
Physics-based and statistic-based models for describing seismic occurrence are two sides of the same coin. In this article we compare the temporal organization of events obtained i…
Estimating generation time of SARS-CoV-2 variants from the daily incidence rate
Eugenio Lippiello, Giuseppe Petrillo, Lucilla de Arcangelis
The identification of the transmission parameters of a virus is fundamental to identify the optimal public health strategy. These parameters can present significant changes over ti…
The influence of the brittle-ductile transition zone on aftershock and foreshock occurrence
Giuseppe Petrillo, Eugenio Lippiello, François Landes +1
Aftershock occurrence is characterized by scaling behaviors with quite universal exponents. At the same time, deviations from universality have been proposed as a tool to discrimin…
Fault heterogeneity and the connection between aftershocks and afterslip
Eugenio Lippiello, Giuseppe Petrillo, François Landes +1
Whether aftershocks originate directly from the mainshock and surrounding stress environment or from afterslip dynamics is crucial to the understanding of the nature of aftershocks…
