Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 8.1 occurred in the kermadec ISLANDS region at 1928 UTC on thursday MARCH 4 2021
TSUNAMI waves have been observed
Based on all available data hazardous TSUNAMI waves are forecast for some coasts

Threat Forecast

TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of antarctica... chile... colombia... COSTA RICA ecuador... mexico... nicaragua... panama... peru.
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.

Tsunami Observations

Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 8.1 occurred in the kermadec ISLANDS region at 1928 UTC on thursday MARCH 4 2021
TSUNAMI waves have been observed
Based on all available data hazardous TSUNAMI waves are forecast for some coasts

Threat Forecast

TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of antarctica... chile... colombia... COSTA RICA ecuador... mexico... nicaragua... panama... peru.
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.

Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 8.1 occurred in the kermadec ISLANDS region at 1928 UTC on thursday MARCH 4 2021
TSUNAMI waves have been observed
Based on all available data hazardous TSUNAMI waves are forecast for some coasts

Threat Forecast

TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of antarctica... chile... colombia... COSTA RICA ecuador... mexico... nicaragua... panama... peru.
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.

Tsunami Observations

The following are tsunami wave observations from coastal and/or deep-ocean sea level gauges at the indicated locations the maximum tsunami height is measured with respect to the normal tide level

Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 8.1 occurred in the kermadec ISLANDS region at 1928 UTC on thursday MARCH 4 2021
TSUNAMI waves have been observed
Based on all available data hazardous TSUNAMI waves are forecast for some coasts

Threat Forecast

TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of antarctica... chile... colombia... COSTA RICA ecuador... mexico... nicaragua... panama... peru.
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.

Tsunami Observations

The following are tsunami wave observations from coastal and/or deep-ocean sea level gauges at the indicated locations the maximum tsunami height is measured with respect to the normal tide level

Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 8.1 occurred in the kermadec ISLANDS region at 1928 UTC on thursday MARCH 4 2021
TSUNAMI waves have been observed
Based on all available data hazardous TSUNAMI waves are forecast for some coasts

Threat Forecast

TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of antarctica... chile... colombia... COSTA RICA ecuador... mexico... nicaragua... panama... peru.
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.

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.

Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 8.1 occurred in the kermadec ISLANDS region at 1928 UTC on thursday MARCH 4 2021
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 kermadec islands.
TSUNAMI waves reaching 1 to 3 meters above the tide level are possible along some coasts of NEW caledonia... and vanuatu.
TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of antarctica... australia... chile... colombia... COOK islands... COSTA rica... ecuador... fiji... FRENCH polynesia... kosrae... mexico... nauru... nicaragua... panama... peru... PITCAIRN islands... pohnpei... samoa... SOLOMON islands... tonga... and WALLIS and futuna.
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.

Tsunami Observations

The following are tsunami wave observations from coastal and/or deep-ocean sea level gauges at the indicated locations the maximum tsunami height is measured with respect to the normal tide level

Key information extracted from original GTS message :

Evaluation

An earthquake with a preliminary magnitude of 8.1 occurred in the kermadec ISLANDS region at 1928 UTC on thursday MARCH 4 2021
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 kermadec islands.
TSUNAMI waves reaching 1 to 3 meters above the tide level are possible along some coasts of NEW caledonia... and vanuatu.
TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of antarctica... australia... chile... colombia... COOK islands... COSTA rica... ecuador... fiji... FRENCH polynesia... kosrae... mexico... nauru... nicaragua... panama... peru... PITCAIRN islands... pohnpei... samoa... SOLOMON islands... tonga... and WALLIS and futuna.
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.

Tsunami Observations

The following are tsunami wave observations from coastal and/or deep-ocean sea level gauges at the indicated locations the maximum tsunami height is measured with respect to the normal tide level

Evaluation

An earthquake with a preliminary magnitude of 8.1 occurred in the kermadec ISLANDS region at 1928 UTC on thursday MARCH 4 2021
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 kermadec islands.
TSUNAMI waves reaching 1 to 3 meters above the tide level are possible along some coasts of NEW caledonia... and vanuatu.
TSUNAMI waves reaching 0.3 to 1 meters above the tide level are possible for some coasts of antarctica... australia... chile... colombia... COOK islands... COSTA rica... ecuador... fiji... FRENCH polynesia... kosrae... mexico... nauru... NEW zealand... nicaragua... panama... peru... PITCAIRN islands... pohnpei... samoa... SOLOMON islands... tonga... and WALLIS and futuna.
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.
