Tips for your answer

1. Start with a precise definition + context
Briefly define Earthquake Lights (EQL) and mention their link with seismic activity (pre-, co-, or post-earthquake phenomena).
2. Explain mechanism in a flow (use keywords)
Use a step-wise chain:
Tectonic stress → activation of p-holes → charge migration → ionization → plasma glow
(Keep it structured, almost like a mini flowchart.)
3. Add value in conclusion (significance + limitation)
Mention early warning potential + scientific importance, but balance it with rarity and lack of predictability to show analytical depth.
