Earthquake Productivity Law in a Wide Magnitude Range

Frontiers 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 ...

Study of Temporal Analysis on Earthquake Data and Statistical Seismology of Nepal

, 2021
An earthquake is the greatest terrifying natural disaster that can do significant damages. A 7.8 magnitude earthquake struck Barpak, which is located about 81 kilometers northwest of Kathmandu killing thousands and affecting millions of citizens on 25th ...

Saturn's Seismic Rotation Revisited

The 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.

Investigating the spatial correlations in univariate random fields of peak ground velocity and peak ground displacement considering anisotropy

Geoenvironmental Disasters, 2021
The results of seismic risk assessment of spatially distributed infrastructure systems are significantly influenced by spatial correlation of earthquake intensity measures (IM).

Pervasive Foreshock Activity Across Southern California

Geophysical Research Letters, 2019
Foreshocks have been documented as preceding less than half of all mainshock earthquakes. These observations are difficult to reconcile with laboratory earthquake experiments and theoretical models of earthquake nucleation, which both suggest that ...

Statistical seismology: preface to the topical issue

, 2017
It is widely recognized that Seismology, the quantitative study of which started in the 19th century, has not yet achieved the ambitious target of predicting time, place and intensity of strong earthquakes in such a way as to allow concrete actions to ...

Structured regularization based velocity structure estimation in local earthquake tomography for the adaptation to velocity discontinuities

Earth, Planets and Space, 2022
We propose a local earthquake tomography method that applies a structured regularization technique to determine sharp changes in Earth’s seismic velocity structure using arrival time data of direct waves.

Research on Maximum Likelihood b Value and Confidence Limits Estimation in Doubly Truncated Apparent Frequency–Amplitude Distribution in Rock Acoustic Emission Tests

Mathematics, 2022
The b value deduced from the Gutenberg–Richter law is an important parameter for sequence and precursory analyses, both in laboratory acoustic emission tests and seismology.

3D reconstruction of coronal loops by the principal component analysis [PDF]

, 2013
Knowing the three dimensional structure of plasma filaments in the uppermost part of the solar atmosphere, known as coronal loops, and especially their length, is an important parameter in the wave-based diagnostics of this part of the Sun.
