Despite their short warning times (seconds to tens of seconds)earthquake early warning systems can become useful tools in riskmitigation provided their design is robust and utilizes theregional tectonics. Bucharest can serve as a good example forsuch a system with a warning time of 25 seconds. Integration ofearly warning into real-time information systems turns out beingcrucial in disaster management.
