Identification and Temporal Characteristics of Earthquake Clusters in Selected Areas in Greece

open access: yesApplied Sciences, 2022
The efficiency of earthquake clustering investigation is improved as we gain access to larger datasets due to the increase of earthquake detectability.

A 20-Year Journey of Forecasting with the “Every Earthquake a Precursor According to Scale” Model

open access: yesGeosciences, 2022
Nearly 20 years ago, the observation that major earthquakes are generally preceded by an increase in the seismicity rate on a timescale from months to decades was embedded in the “Every Earthquake a Precursor According to Scale” (EEPAS) model.

New Physical Implications From Revisiting Foreshock Activity in Southern California

open access: yesGeophysical Research Letters, 2023
Foreshock analysis promises new insights into the earthquake nucleation process and could potentially improve earthquake forecasting. Well‐performing clustering models like the Epidemic‐Type Aftershock Sequence (ETAS) model assume that foreshocks and ...

Earthquake Productivity Law in a Wide Magnitude Range

open access: yesFrontiers in Earth Science, 2022
Earthquakes are usually followed by aftershocks. The number of aftershocks—the so-called productivity—depends on the magnitude of the earthquake. In seismic modeling it is usually assumed that the number of aftershocks is approximately the same for ...

On the origin of exponential growth in induced earthquakes in Groningen [PDF]

open access: yes, 2016
The Groningen gas field shows exponential growth in earthquakes event counts around a magnitude M1 with a doubling time of 6-9 years since 2001. This behavior is identified with dimensionless curvature in land subsidence, which has been evolving at a ...

Automatic Reconstruction of Fault Networks from Seismicity Catalogs: 3D Optimal Anisotropic Dynamic Clustering [PDF]

open access: yes, 2007
We propose a new pattern recognition method that is able to reconstruct the 3D structure of the active part of a fault network using the spatial location of earthquakes.

Expected seismicity and the seismic noise environment of Europa [PDF]

open access: yes, 2017
Seismic data will be a vital geophysical constraint on internal structure of Europa if we land instruments on the surface. Quantifying expected seismic activity on Europa both in terms of large, recognizable signals and ambient background noise is ...

Saturn's Seismic Rotation Revisited

open access: yesThe Planetary Science Journal, 2023
Normal mode seismology is a promising means of measuring rotation in gas giant interiors, and ring seismology presents a singular opportunity to do so at Saturn.

Giant star seismology [PDF]

open access: yes, 2017
The internal properties of stars in the red-giant phase undergo significant changes on relatively short timescales. Long near-uninterrupted high-precision photometric timeseries observations from dedicated space missions such as CoRoT and Kepler have ...

New horizon in the statistical physics of earthquakes: Dragon-king theory and dragon-king earthquakes

open access: yes地球与行星物理论评
A systematic quantitative investigation into whether the mechanisms of large earthquakes are unique could significantly deepen our understanding of fault rupture and seismicity patterns. This research holds the potential to advance our ability to predict
