Tsunami Detection Model for Sea Level Measurement Devices

Sea-level measurements are of critical importance in verification of a tsunami generation. When a large earthquake occurs in a subduction zone and the Regional Tsunami Service Provid-ers of UNESCO/IOC issue alerts, sea level measurements are critically important to verify the tsunami generation to take further actions (i.e. evacuation of coastal areas). However, in some cases, if the tsunami source is very close to the coast, there is not enough time between the iden-tification of an event and the issue of alerting bulletins. Also, when the tsunami is not generated by a large earthquake but is due to an atypical source (i.e. landslide or volcanic eruption) or a prior information from the earthquake is not available before the arrival of the tsunami, it is of vital importance to have other means for the verification of the tsunami generation. The algo-rithm presented in this paper, already installed in several operation al devices is capable of ac-quiring the data, processing them and then moving them back into the JRC or any other relevant database, can also be used for any sea level measurement of interest with corresponding trig-gering criteria.
