Early Warning – Some Recent Developments

Olaf Neussner


Recent advances in early warning have been observed in science and technology as well as the overall effectiveness of end-to-end early warning systems.

The accuracy in predicting earthquakes is slowly increasing, but it is still far from being applicable to routine early warning systems. Tests of landslide warning systems based on motion sensors of slopes are progressing and might be used more widespread in the coming years.

Fast communication is not a real issue for today’s technology, but spreading alert information quickly to large communities without access to modern communication equipment remains a problem. However, some experiences of locally anchored early warning systems point to higher effectiveness if they are managed decentralized within communities.

Though EWS have to be adjusted to local circumstances the growing number of temporary visitors (e.g. migrants, tourists) in the world, require some type of international standard easily understood by everyone. While the wording may be local plus internationally used languages (e.g. English), signs/icons should follow international conventions.
