Recent minor earthquakes in the Aegean Sea near Turkey and Greece were accompanied by unusual glowing lights in the sky. This rare occurrence has once again brought attention to the fascinating phenomenon known as earthquake lights, which continues to puzzle scientists around the world.

What Are Earthquake Lights?

Earthquake lights are unusual luminous events that appear as flashes, glowing spheres, streaks, or vertical beams in the sky. These lights can occur before, during, or shortly after an earthquake. Unlike fire or explosions, they are linked to electrical activity generated within the Earth’s crust.

Although rare, such lights have been reported in several seismic regions globally, making them an important subject of scientific study.

Scientific Explanation Behind Earthquake Lights

The formation of earthquake lights is closely related to tectonic stress. As rocks beneath the Earth’s surface are subjected to intense pressure due to plate movements, they generate electrical charges.

Minerals like quartz play a key role in this process. When stressed, these minerals produce electric currents that travel through cracks and fault lines toward the Earth’s surface. Once these charges reach the atmosphere, they interact with air molecules, causing ionisation. This results in the formation of plasma, which appears as glowing light in the sky.

Role of Geological Structures

Researchers have found that earthquake lights are more likely to occur in regions with specific geological formations, especially areas with vertical or straight fault lines such as rift zones. These structures allow electrical charges to move more easily from deep underground to the surface.

This explains why earthquake lights are not seen during every seismic event, as their occurrence depends on both the type of rocks present and the structure of faults.

Scientific Importance

Earthquake lights are still not fully understood and remain an active area of research. While they are not yet reliable indicators for predicting earthquakes, studying them helps scientists better understand the electrical behaviour of rocks and stress patterns within the Earth’s crust.

With further research and observation, earthquake lights may contribute to improved knowledge of seismic activity and related atmospheric phenomena.

Important Facts for Exams

• Earthquake lights are rare luminous phenomena linked to earthquakes

• Caused by electrical charges generated in stressed rocks

• Ionisation of air molecules produces visible plasma

• More common in quartz-rich regions with vertical fault lines
