How Phones Detected Earthquake Early
Dr. Bassem Nabawi, head of the National Institute for Astronomical and Geophysical Research, revealed the truth about the notifications received by some citizens on their mobile phones prior to feeling an earthquake. He clarified that these alerts are not predictions of earthquakes but are based on an early warning system that detects the initial, non-damaging seismic waves and sends an alert before the surface waves—felt by humans—arrive. He emphasized that predicting earthquakes in advance is scientifically impossible, and the time gap between the alert and the perception of the tremor does not exceed one or two seconds; it depends on the speed at which seismic waves travel.
