The worldâs only earthquake warning system likely helped limit damage and loss of life. The earthquake that struck Japan early this morning was the worst seen in that country for over 300 years (with a local magnitude of 8.9). Hundreds have been killed and injured so far, but the loss of life was likely limited by two vital early warning technologies: a new earthquake alert system, and ocean-based tsunami warning system. The earthquake warning system, which has never been triggered before, automatically issued alerts via television and cell phones shortly after the first, less harmful, shock wave was detected, providing time for many people to prepare for the more powerful shock wave that followed.
