 The Local Tsunami Alert System [``SLAT'']: A Computational Tool for the Integral Management of a Tsunami EmergencyF. Ramirez and P. Perez Natural Hazards: Journal of the International Society for the Prevention and Mitigation of Natural Hazards, 2004, vol. 31, issue 1, 129-142 Abstract: During a tsunami emergency numerous local authorities responsible for the security oflocal persons and businesses which function in the coastal zone are required to makecritical decisions within a very short time frame. It is known that the consequencesof the situation will depend on the quality and quantity of decisions which they makeor allow to occur at the critical time. Based on this concept, the Local System of Tsunami Alert (SLAT; Spanish) was developed. This is a computational tool designed for the automatic implementation of integral management for an emergency of this type. The System is able to immediately evaluate possible risks and determine thetype of alert represented (Red, Yellow, Green, Blue, and Celeste) if relevantdata such as coordinates of the epicenter, magnitude, date, and origin of theearthquake (>6.5° on the Richter scale) threatening the Pacific areknown. Other relevant data include location of the coastal or marine epicentreand the superficial hypocenter. The relevant data may now be obtained fromthe internet from international seismological services, and fed into the programto give the most probable time for arrival of the first wave train at a given pointof interest, whether this be a port, bathing area, generating plant, or coastal city.The program also gives the time required for the first wave train to arrive at agiven coast, and displays a menu of previously planned actions to be taken accordingto the type of alert. It also permits dissemination of a bulletin with critical data and action plans by fax or e-mail to scattered users as well as for storage on the computer disc. The system is designed in a way that the user always confirms with authorities that anevent has in fact been generated. On a local scale, the user is required to prepare an operative emergency plan of action to be followed by his company, community, or municipality, to be followed for each type of alert. The System permits carrying out test exercises with the users, as well as simulationof past events. Knowledge concerning past events permits understanding correctdesign of emergency action plans for mitigation of potential present and future events.This software is specifically designed for the Pacific Coast of South America, and isprepared in Spanish, with the intention of improving responses of inhabitants of coastalareas to the potential threat from tsunamis.
