A study published in Seismological Research Letters on October 11, 2024, presents new algorithms to enhance earthquake forecasting, marking a significant advancement in understanding how seismic activity escalates before major earthquakes. These improvements in medium-term forecasting hold crucial implications for public preparedness and effective risk management, particularly in earthquake-prone regions.
A new study was conducted to understand the precursors to the 2021 Fukushima Prefecture Offshore Earthquake (Mj = 7.3), which occurred on February 13, 2021, off the coast of Fukushima, Japan, as an aftershock of the 2011 Tōhoku earthquake and tsunami. The investigation, led by Masashi Hayakawa and Yasuhide Hobara, focused on the Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) channels and multi-parameter anomalies that occurred before the earthquake.
A recent study by Társilo Girona of the University of Alaska Fairbanks and Kyriaki Drymoni of Ludwig-Maximilians-Universität in Munich proposed a new machine learning technique for predicting big earthquakes months in advance. The study, published in Nature Communications on August 28, 2024, intended to improve earthquake predictions and public safety.
Researchers from Penn State and Brown University have uncovered how rocks from ancient subduction zones can forecast tectonic behaviors between significant earthquakes, enhancing our ability to predict such natural disasters.
Researchers reporting in AGU’s JGR Solid Earth identified changes in the magnetic field near intermediate-large earthquakes in California in the days before the earthquakes happened, providing evidence that there is a physical change that can be observed in the days before an earthquake.
A new study published recently in Remote Sensing proposes the implementation of machine learning support vector machine (SVM) technique, applied with GPS ionospheric total electron content (TEC) pre-processed time series estimations, to evaluate potential precursors caused by earthquakes.
A new study published in Earth, Planets and Space sheds new light on the electromagnetic anomalies occurring before large earthquakes. The research supports the hypothesis that fault rupture progresses just before an earthquake, and the invading gas is charged and…
Previous studies have shown elevated levels of radon in the atmosphere prior to the mainshock of a huge inland earthquake. However, in a new study, researchers revealed an anomaly in this phenomenon as they found that the concentration of the radioactive element…
On August 21, 2020, the fire department in Kanagawa Prefecture, Japan, received numerous calls from residents reporting an unusual smell in the area over the course of an hour. Seismologist Manabu Takahashi suggests that the strange phenomenon may be a precursor of…
A new study published in the Nature Scientific Reports on July 13 suggests that powerful eruptions on the Sun can trigger large earthquakes on Earth. In the paper, the authors analyzed 20 years of proton density and velocity data, as recorded by the SOHO satellite,…
