Project Title: Nshm-consistent Tsunami Hazard Mapping for Puerto Rico and the Us Virgin Islandsproject Period: 7 1 2026 Through 6 30 2027PROJECT Purpose: the Development of an Nshm-consistent Tsunami Hazard Model for Puerto Rico and the Us Virgin Islands.activities to Be PERFORMED:1. Development of Tsunami Sources That Fall Outside of the Domain of the Nshmp (e.g. South Caribbean Deformed BELT)2. Implementing the Current Usgs NSHM Source Model for Tsunami HAZARD3. Calculate Offshore Tsunami Hazard Following Asce 7-23 PROCEDURES4. the Identification of Areas in the NSHM Model That Need More Attention or Elaboration to Be Used for Tsunami Hazarddeliverables and Expected Outcome: a Database of Offshore Probabilistic Tsunami Hazard for Puerto Rico and the Us Virgin Islands Suitable for Further Inundation Mapping by Local Entities, at Densely Spaced Points (1-2KM Separation) Offshore Following a Suitable Depth Contour (e.g. 100M-200M). a Database of Tsunami Hazard Curves for All Above Points a Database of Source Disaggregation for Each of the Offshore Points Probabilistic Subsidence Maps a Report Describing the Project Software Used to Perform the Pthaintended Beneficiaries: the Engineering Community Working on Puerto Rico and the Us Virgin Islands Emergency Managers and the Community Various Government Entities on the Islands (e.g. Land-use Planning)this Objective Is Directly Aligned With a Priority Topic in the Request for Proposals on Priority Topics for Central and Eastern Us (CEUS) Element I: Ceus Element I. National and Regional Earthquake Hazards Assessments, Improve Assessments of the Earthquake Potential of the U.s. Caribbean Territories and Surrounding Offshore Faults, the Portion of the Antilles Subduction Zone That Causes Hazards in U.s. Territories, Ground Motions in the Region, and Associated Hazards (landslides, Tsunamis, Ground Failure) to the U.s.caribbean Territories and Atlantic Seaboard.subrecipients: N a
