We're in the initial stages of building an Open Tsunami Alerting
System (OTAS) based on the suggestion in Bob Cringely's 2004/12/30
column[1]. Although work has just started, we've established a few
basic principles: OTAS will be very lightweight; will use openly
available geophysical or seismic data sources; will be highly
distributed and decentralized; and will be built to run on very
low-powered commodity hardware.
We currently foresee using Python and Java, but we aren't religious
about it.
Discussion and on-going notes can be found at the OTAS blog,
