POTENTIAL IMPACTS
-----------------

* A TSUNAMI IS A SERIES OF WAVES. THE TIME BETWEEN WAVE CRESTS
CAN VARY FROM 5 MINUTES TO AN HOUR. THE HAZARD MAY PERSIST
FOR MANY HOURS OR LONGER AFTER THE INITIAL WAVE.

* IMPACTS CAN VARY SIGNIFICANTLY FROM ONE SECTION OF COAST TO
THE NEXT DUE TO LOCAL BATHYMETRY AND THE SHAPE AND ELEVATION
OF THE SHORELINE.

* IMPACTS CAN ALSO VARY DEPENDING UPON THE STATE OF THE TIDE AT
THE TIME OF THE MAXIMUM TSUNAMI WAVES.

* PERSONS CAUGHT IN THE WATER OF A TSUNAMI MAY DROWN... BE
CRUSHED BY DEBRIS IN THE WATER... OR BE SWEPT OUT TO SEA.


TSUNAMI OBSERVATIONS
--------------------

* THE FOLLOWING ARE TSUNAMI WAVE OBSERVATIONS FROM COASTAL

Key information extracted from original GTS message :
Evaluation

  • An earthquake with a preliminary magnitude of 8.2 occurred off the coast of chiapas MEXICO at 0449 UTC on friday SEPTEMBER 8 2017
  • TSUNAMI waves have been observed
  • Based on all available data hazardous TSUNAMI waves are forecast for some coasts
Threat Forecast

  • TSUNAMI waves reaching more than 3 meters above the tide level are possible along some coasts of mexico.
  • TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of AMERICAN samoa... antarctica... COOK islands... ecuador... EL salvador... fiji... FRENCH polynesia... guatemala... kiribati... NEW zealand... samoa... tokelau... tuvalu... vanuatu... and WALLIS and futuna.
  • TSUNAMI waves are forecast to be less than 0.3 meters above the tide level for the coasts of australia... chile... china... chuuk... colombia... COSTA rica... guam... hawaii... honduras... howland and baker... indonesia... japan... JARVIS island... johnston atoll... kermadec islands... kosrae... malaysia...

  • Actual amplitudes at the coast MAY vary from forecast amplitudes due to uncertainties in the forecast and local features. in particular maximum TSUNAMI amplitudes on atolls and at locations with fringing or barrier reefs will likely be much smaller than the forecast indicates.
  • For other areas covered by this product a forecast has not yet been computed. the forecast will be expanded if necessary in subsequent products.
