PMEL engineers deployed a Deep-ocean Assessment and Reporting of Tsunamis (DART®) 4th generation monitoring system off the coast of Oregon last week. This system is an enhanced version of the DART®-ETD (Easy to Deploy) technology developed at NOAA-PMEL that incorporates advancements in sensors, software and power management to detect and measure near-field tsunami with unprecedented resolution. An improved pressure sensor will be able to detect and measure a tsunami closer to the earthquake source providing valuable information to warning centers even faster.

Please visit the DART® website for more information on this technology.
