A revolutionary research published in “Journal of Applied Geodesy” suggests that earthquakes may show warning signs much earlier than previously thought. These signs, detectable through the use of satellites, could transform the way we prevent natural disasters, offering the possibility of developing more effective early warning systems.
The professor Mehdi Akhoondzadeh of the University of Tehran analyzed a series of satellite data linked to the earthquakes that struck the border between Turkey and Syria on February 6, 2023. Among the data examined, there were those coming from the Chinese satellite for seismic-electromagnetic study, CSES-01, and from the Swarm mission of the European Space Agency, composed of three satellites.
The analysis highlighted anomalies in the earth’s surface temperature up to 12-19 days before the earthquakes and anomalies in atmospheric parameters between 5 and 10 days before the events. These measurements included the water vapor, methane levels, ozone and carbon monoxide.
Even more relevant were anomalies in the ionosphere, observed between 1 and 5 days before the earthquakes, which included parameters such as electron density and electron temperature.
These discoveries suggest that signals of an impending earthquake originate from the ground and gradually manifest through the atmosphere until reaching the ionosphere. This emerging pattern of anomalies offers a new perspective on how early warning systems for earthquakes could be developed, thereby reducing destruction and saving lives.
Professor Akhoondzadeh commented: “Using data from the CSES-01 satellite, anomalies in the ionosphere before the earthquakes in Turkey were detected for the first time. By studying anomalies associated with multiple earthquake precursors, the certainty in detecting real anomalies increases and this can be effective in creating earthquake warning systems with a low number of false alarms.”
The analysis continues andAccumulating data from researchers around the world are crucial to confirming these models and refining forecasting methods. Every earthquake analyzed and every data model expanded brings scientific research closer to a more complete understanding of how and when these disastrous events occur, paving the way for future developments that may one day allow us to predict earthquakes accurately and timely.
