Evaluation

An earthquake with a preliminary magnitude of 7.4 occurred near the west coast of honshu JAPAN at 0710 UTC on monday JANUARY 1 2024
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 dpr of korea... japan... and russia.
TSUNAMI waves are forecast to be less than 0.3 meters above the tide level for the coasts of REPUBLIC of korea.
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
