The SINAMOT (Sistema Nacional de Monitoreo de Tsunamis), is responsible for increasing Costa Rica tsunami preparedness, by characterizing the threat, increasing community preparedness and strengthening the existing tsunami warning standards of practice.
The National Tsunami Warning Center (NTWC), SINAMOT evaluates tsunami hazard models including near and far field scenarios. We use several numerical models, which incorporate data such as bathymetry and LIDAR topography to adequately assess potential run up at the coast, from a wide range of possible tsunami scenarios. This information is also used to generate tsunami inundation maps and for some communities, tsunami evacuation maps as well.
The results are presented to different stakeholders and decision makers such as national and local government, emergency managers and emergency committees. Currently, we have guided more than 40 communities in the designing of their own tsunami evacuation map, and about 15 of them also in their tsunami evacuation plan. Two communities have been awarded as Tsunami Ready by IOC/UNESCO.
However, there are still more than a hundred coastal communities that have not received training in tsunami hazard. In addition, we should further explore non-seismic tsunami sources, such as nuclear test, landslides and perform tsunami inundation modeling at more locations.
