Tsunami evaluation: not available (Td*T50Ex Warning Level: GREY )
    (DISCLAIMER: Tsunamigenic evaluation is based on the value of the Td*T50Ex Warning Level. This evaluation only concerns the likelihood that this earthquake generated a regional or larger scale tsunami. This evaluation DOES NOT concern the size and effects of a possible tsunami, which depend on details of the earthquake source, ocean bathymetry, coastal distances and population density, and many other factors.) This evaluation DOES NOT apply to and DOES NOT EXCLUDE the possibility that this earthquake generated a local tsunami, which can be destructive along coasts within a 100 km or more from the earthquake epicenter.
