  • An earthquake with a preliminary magnitude of 7.4 occurred near the coast of oaxaca MEXICO at 1529 UTC on tuesday JUNE 23 2020
  • 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 mexico.
  • TSUNAMI waves are forecast to be less than 0.3 meters above the tide level for the coasts of COSTA rica... ecuador... EL salvador... guatemala... hawaii... honduras... nicaragua... panama... and 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.
