The
Deep-ocean Assessment and Reporting of Tsunamis (DART) is a world-wide tsunami warning system. It is comprised of surface buoys that are anchored to BPR (Bottom Pressure Recording) devices. These
DART stations have been installed at locations around the world with a history of tsunami activity.
These stations, run by the National Oceanic and Atmospheric Administration (NOAA), are of particular interest right now due to the recent
8.9 earthquake and subsequent tsunami in Japan.
Presently there are 39 stations:
Pressure, temperature and estimated sea surface height readings are collected every 15 seconds. On the map at
this link you can click on each station and get live accurate readings.
I hope no
other countries have to experience what Japan is going through right now.
