Earthquake precursors associated with the Turkey earthquakes

[pinball1970]

TL;DR

Satellite data reveal electromagnetic anomalies up to 19 days before 2023 Turkey earthquake.
Early warning potential.

"Such anomalies are known as earthquake precursors, and although researchers are aware of them, it has been difficult to definitively identify a pattern of so-called red flags that could indicate an impending earthquake. This is because of the complexity of precursor interactions and their variability in different earthquakes and geographical regions. However, with every earthquake that researchers analyze using increasingly sophisticated satellite technology, these patterns are slowly emerging."

From the abstract

"The purpose of this study is to investigate the relation between pre-earthquake anomalies observed in different layers of the earth system and explore the earthquake mechanism of LAIC (Lithospheric Atmospheric Ionospheric Coupling) associated with earthquake precursors."

Tsunami generating earthquakes are not mentioned. A similar system for detection for underwater quakes would be useful too, Indonesia 2005 and Japan 2011

That would be useful, but perhaps underwater, the ocean above would dissolve or smear out any collections of ions or electrons perhaps.

I wonder if this anomaly is periodic, i.e., does it occur with regularity, has it happened since? If so, then it may be simply coincidental. If the magnitude of the anomaly increased up to and just before the earthquake, then subsided to 'normal' levels, then perhaps there is a connection.

Would a significant build up of stress, or perhaps gas pressure, or leakage of gases from the lithosphere cause and ion, electron, chemical effect that indicates the potential for an earthquake? Has it been observed prior to or around the time of other large earthquakes, or perhaps substantial volcanic eruptions? Are volcanic eruptions different - or dependent on the type of volcano?


I am aware of periodic changes in atmospheric density in stratosphere, thermosphere, and exosphere, which is important with respect to LEO and GEO satellites.

I attended a presentation of atmospheric changes affecting LEO satellites, showing multiple orbital plots, and there were periodic blips (mini-spikes), which caused me to wonder if those correlated with passing over continents vs oceans, in addition to day/night effects, and solar activity.

SS orbits at an altitude of between 370–460 km (200–250 nmi). Its falls towards Earth continually due to atmospheric friction and requires periodic rocket firings to boost the orbit. The ISS orbital inclination is 51.6°, permitting ISS to fly over 90% of the inhabited Earth.
