Tidal stations and bench marks : tools for spatial information management
Velez-Rodriguez, Linda L.
The Island of Puerto Rico has approximately 325 Km. of shore lines which are vulnerable to the occurrence of a tsunami generated by local earthquakes and submarine landslides. We are also at risk from regional Caribbean and distant Atlantic tsunamis. In order to register and document these types of phenomena we need to install a state of the art tsunami ready tide gauge network that can detect, record and analyze the data from sea level stations along with earthquake information. An innovative plan to install an alert system for tsunamis on the Island of Puerto Rico at strategic locations can be a critical step toward safety alert systems for the population. These sites are Arecibo, Fajardo, Guayanilla, Mayaggez, Yabucoa and the North coast of Vieques. A central recording system will be installed at the Puerto Rico Seismic Network to record and analyze the data from these and other tsunamis ready tide gauges that are going to be installed by National Oceanographic and Atmospheric Administration (NOAA) in Puerto Rico (San Juan, Parguera, Mona, Aguadilla, Vieques South and Culebra) and the Virgin Islands and the Tsunamis Ready Buoys to be installed in the Atlantic and the Caribbean. The paper will describe the installations of the tidal stations and the tidal bench marks procedures and selections, in addition to the differential leveling and GPS observations.
