30 abril 2012 | EN | FR The researchers say current models are
too simple to accurately forecast tsunami behaviour Tsunami
forecasting could be significantly improved if the computer
models used to predict wave behaviour were to incorporate data
on the waves' complex behaviour as they come into shore and
break, according to researchers. Writing in a themed issue of
Philosophical Transactions of the Royal Society A, the
researchers describe the current state of tsunami dynamics and
forecasting, and suggest policy changes aimed at better
protecting seaside communities. They note that tsunami warning
systems have generally improved, thanks to the deployment of
ocean buoys tethered to the seabed, which can detect underwater
earthquakes. "Once the initial data are known, forecasting the
propagation of the tsunami across the open ocean is relatively
easy," according to one of the paper's authors, Harvey Segur, a
tsunami expert at the University of Colorado Boulder, United
States. Currently these data are fed into c
