Statistical analysis of daily seismic event rate as a precursor to volcanic eruptions [PDF]

, 2003
We analyse time series of daily seismic event rate for the Kilauea, Hawaii, volcano between 1959 and 2000. Individual eruptions are not always preceded by an increase in event rate, and many increases in event rate do not lead to eruption.

Earthquake precursors: Banished forever? [PDF]

Eos, Transactions American Geophysical Union, 1998
“When a rupture starts, how can it know where will it stop?” [Gregory Podyapolsky, 1973]Podyapolsky, a brilliant theorist, made this comment many years ago, upon perceiving that the earthquake prediction bandwagon in the Soviet Union was gaining speed. Twenty years later, we can observe just how far the bandwagon has gone.

Is It Possible to Predict Strong Earthquakes?

, 2014
The possibility of earthquake prediction is one of the key open questions in modern geophysics. We propose an approach based on the analysis of common short-term candidate precursors (2 weeks to 3 months prior to strong earthquake) with the subsequent ...

Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

Deep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Long short-term memory networks for earthquake detection in Venezuelan regions [PDF]

, 2019
Reliable earthquake detection and location algorithms are necessary to properly catalog and analyze the continuously growing seismic records. This paper reports the results of applying Long Short-Term Memory (LSTM) networks to single-station three ...

Monitoring Surface Deformation Before the M7.0 Kumamoto and M6.6 Chitose Earthquakes for Precursor [PDF]

E3S Web of Conferences
Earthquakes have resulted in significant damage; however, the extent of the ground observation coverage remains limited. Thus, a deeper understanding of seismic activity and its precursors holds promise in mitigating earthquake hazards.

A review on precursors of the 1999 Mw7.6 Chi-Chi, Taiwan, earthquake

Terrestrial, Atmospheric and Oceanic Sciences, 2021
Earthquake prediction has been a long-term debatable problem in earthquake science. There were numerous studies of possible precursors after the Mw 7.6 Chi-Chi, Taiwan, earthquake of 20 September 1999.
