India Developing Early Earthquake Warning System

India is working on a system to give people a heads-up before an earthquake's strong shaking arrives.

Earthquakes send out two types of waves: P-waves, which arrive first, and S-waves, which cause the most damage.

The new system will detect the P-waves and use that information to predict when the harmful S-waves will hit.

This should give people time to prepare and protect themselves.

India is at risk for earthquakes, and this system could save lives and protect important buildings.

It's expected to be ready in about ten years.
