The Possible Observation of Slow Slip Events Prior to the Occurrence of the 1999 Chi-Chi Earthquake

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2012
Possible short-term precursors several days before the Taiwan Chi-Chi earthquake (Mw = 7.6) on 20 September 1999 were observed by examining crustal deformation that were directly integrated from broadband velocity seismograms.

The power of the past: materializing collective memory at early medieval lordly centres

open access: yesEarly Medieval Europe, Volume 34, Issue 1, Page 34-69, February 2026.
The repurposing of earlier sites and monuments is an enduringly popular theme in early medieval archaeology, but in England it has attracted little interest among Late Saxon and early post‐Conquest studies. From the tenth century, however, an increasingly prevalent pattern is discernible of secular lords locating their power centres in relation to ...

Abnormally Large Magma Flux Does Not Lead to Eruption in Subduction Zone Calderas: The 2022–2023 Episode of Uplift of Aniakchak Crater (Aleutians)

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Observations of ground deformation provide insights on the triggering mechanisms of eruptions. At Aniakchak Crater (Aleutians) InSAR measured ∼ ${\sim} $72 cm of uplift in less than 7 months between 2022 and 2023. The uplift can be explained by the inflation of a point pressure source at a depth of 3.2 km.

Evaluation of Proposed Earthquake Precursors

open access: yesEos, Transactions American Geophysical Union, 1991
AGU's Evaluation of Proposed Earthquake Precursors presents the first results of a project carried out by the International Association of Seismology and Physics of the Earth's Interior (IASPEI) to evaluate claims about precursors to earthquakes. Only three of 28 nominations were accepted for the Preliminary List of Significant Precursors that IASPEI ...

Are any public-reported earthquake precursors valid? [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2004
This article examines retrospective public-supplied precursor reports statistically, and confirms published hypotheses that some alleged precursors within 100km and within a day prior to the large 1995 Kobe and 1999 Izmit earthquakes, may be valid.

IDENTIFICATION OF ELECTROMAGNETIC ULTRA LOW FREQUENCY (ULF) SIGNAL ANOMALIES AS PRECURSORS OF A MAGNITUDE 5 EARTHQUAKE IN THE SULAWESI REGION

open access: yesJurnal Neutrino: Jurnal Fisika dan Aplikasinya
Sulawesi is situated at the intersection of three tectonic plates the Indo-Australian, Eurasian, and Philippine plates. The Palu Koro fault is one of the primary causes of seismic activity in the Sulawesi region, making it vulnerable to earthquakes on ...

Evidence of fractional-Brownian-motion-type asperity model for earthquake generation in candidate pre-seismic electromagnetic emissions [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2008
Many aspects of earthquake generation still escape our full understanding. Observations of electromagnetic emissions preceding significant earthquakes provide one of the few cases of premonitory events that are possibly related to a subsequent earthquake.

Precursors of Earthquakes: VLF Signals-Ionosphere Relation

open access: yes, 2012
A lot of people have died because of earthquakes every year. Therefore It is crucial to predict the time of the earthquakes reasonable time before it had happed. This paper presents recent information published in the literature about precursors of earthquakes. The relationships between earthquakes and ionosphere are targeted to guide new researches in

Mathematical modeling of earthquake precursors occurring in physical fields

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2016
One of possible relations of stresses in earthquakes centers with physical fields is considered, being expressed in the equations of heat electromagnetic elasticity that are written with the Rabotnov-Lomakin parameters and measurable on the Earth.
