UNESCO’s Assistant Director-General, Flavia Schlegel, stressed that “over the past 10 years, earthquakes were responsible for the highest number of deaths from disasters emanating from natural hazards. More focus is needed to mitigate earthquake disaster risk worldwide,” While over 80 percent of disasters over the past decade have been climate-related, earthquakes are responsible for the highest number of losses of lives, accounting for 70 percent of deaths.

Early warning for hazards such as storms or tsunamis – the latter spawned by earthquakes far from land – have proven their mettle and are being spread worldwide thanks to a range of international initiatives. However, earthquakes are much tougher to deal with, for which early warnings are needed within a much smaller time frame before the destructive damages occur.

“Early warning for earthquakes is almost like the Holy Grail for geologists,” said Patrick Mc Keever, Secretary of the International Geoscience Programme at UNESCO.

Earthquake early warning systems aim to identify and characterize the tremors a few seconds after they begin, calculate the likely intensity of ground shaking for a target city, and deliver alerts to people and infrastructure in harm’s way. Current technology enables detection to be so rapid that an alert can reach some areas before strong shaking arrives, even though the lead time is minuscule. “You’re talking about seconds, tens of seconds, or just a few minutes’ warning,” said Berkeley’s Professor Allen.

But even such a small window can be effectively used to save many lives and to ensure business continuity.
