Comprehensive Earthquake Catalogs and Seismicity Parameters from Incomplete Earthquake Catalogs of Guilan Region, Iran [PDF]

open access: yesCivil Engineering Journal, 2017
Statistics of human losses and financial casualties in Guilan province as one of the most populated and strategic areas in the north of Iran have doubled the importance of having knowledge about earthquake and strategies to reduce its effect. In order to investigate seismic hazard analysis, earthquake records along with selecting the proper distance of

A first-order second-moment calculation for seismic hazard assessment with the consideration of uncertain magnitude conversion [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2013
Earthquake size can be described with different magnitudes for different purposes. For example, local magnitude ML is usually adopted to compile an earthquake catalog, and moment magnitude Mw is often prescribed by a ground motion model.

Earthquake Size Distribution: Power-Law with Exponent Beta = 1/2? [PDF]

open access: yes, 2010
We propose that the widely observed and universal Gutenberg-Richter relation is a mathematical consequence of the critical branching nature of earthquake process in a brittle fracture environment.

The magnitude distribution of earthquakes near Southern California faults [PDF]

open access: yes, 2011
We investigate seismicity near faults in the Southern California Earthquake Center Community Fault Model. We search for anomalously large events that might be signs of a characteristic earthquake distribution.

Nowcasting ETAS Earthquakes: Information Entropy of Earthquake Catalogs

open access: yes, 2023
Earthquake nowcasting has been proposed as a means of tracking the change in large earthquake potential in a seismically active area. The method was developed using observable seismic data, in which probabilities of future large earthquakes can be computed using Receiver Operating Characteristic (ROC) methods.

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

New insights in the seismic history of Monti della Laga area

open access: yesAnnals of Geophysics, 2016
The earthquake of August 24, 2016 hit an Apenninic "border” area, now at the crossroads of four regions, but for many past centuries on the edge of two independent Italian states.

Reverse Detection of Short-Term Earthquake Precursors [PDF]

open access: yes, 2003
We introduce a new approach to short-term earthquake prediction based on the concept of selforganization of seismically active fault networks. That approach is named "Reverse Detection of Precursors" (RDP), since it considers precursors in reverse order ...

A tri-stage cluster identification model for accurate analysis of seismic catalogs [PDF]

open access: yesNonlinear Processes in Geophysics, 2013
In this paper we propose a tri-stage cluster identification model that is a combination of a simple single iteration distance algorithm and an iterative K-means algorithm.

An Improved Earthquake Catalog During the 2018 Kı̄lauea Eruption From Combined Onshore and Offshore Seismic Arrays

open access: yesEarth and Space Science, 2022
The Island of Hawai’i was formed by repeated eruptions of basalts at an oceanic hotspot. Kı̄lauea, the youngest among the subaerial volcanoes of the island, erupted intensely in 2018.
