The Pacific Marine Environmental Laboratory developed the first reliable scientific instrument for detecting tsunamis and quickly alerting scientist when tsunami occurs. The instrument, known as TSUNAMETER, is anchored on the ocean floor and measures changes in water pressure when a tsunami passes above.

How is the size of tsunami's measured?
The size or intensity of tsunami's are measured by considering factors like height of waves, speed of waves etc.May attempts have been done to produce accurate and well-defined systems to measure intensities of Tsunami.Example of some of scales to measure intensity of Tsunami's are:-Sieberg-Ambraseys scaleML scale proposed by Murty & LoomisML scale proposed by Murty & Loomis by Abe
