Early warning hope.

Scientists hope to develop an earthquake early warning system that would give potential victims vital seconds to take cover, it emerged yesterday.

Geologists in California believe they can take advantage of the low-energy waves that often precede a quake to give as much as 40 seconds' advance notice.

It is hoped the warning would allow people to shelter under solid furniture, evacuate buildings, divert aircraft, stop trains, shut down pipelines and computer networks and distance themselves from dangerous machinery or chemicals.

The system is based on TriNet, a network of 155 seismic stations in California.
