Step-by-step explanation:
DART:
Deep ocean assessment and reporting of tusnami (in short DART) is device which is used to indicate the tusnami. Due to tusnami temperature and pressure of seafloor changes and this change in pressure as well as temperature is observed by DART.And with the help of DART we forecast the phenomenon of tusnami. This device is developed by PMEL(Pacific marine environment laboratory) and this is based on integration of real time measurement and modeling technologies.
