The puerto rico seismic network mission

The mission of the Puerto Rico Seismic Network (PRSN) is to rapidly determine the location and size of all earthquakes and tsunamis in the Area of Responsibility (AOR) and to immediately disseminate this information to concerned agencies, scientists, and the general public. PRSN compiles and maintains an extensive seismic database on earthquake parameters, continuous waveforms (earthquakes and sea level) and their effects which serve as a solid foundation for basic and applied earth science/oceanography research in Puerto Rico and the Caribbean.

Tsunami Warning

A tsunami warning isissued when a potential tsunami with significantwidespread inundation is imminent or expected. 

Warnings alert the public that widespread, dangerous coastal flooding accompanied by powerful currents is possible and may continue for several hours after arrival of the initial wave.  

Warnings also alert emergency management officials to take action for the entire tsunami hazard zone. 

Appropriate actions to be taken by local officials may include the evacuation of low-lying coastal areas, and the repositioning of ships todeep waters when there is time to safely do so. 

Warnings may be updated, adjusted geographically, downgraded, or canceled.

To provide the earliest possible alert, initial warnings are normally based only on seismic information.

Tsunami Watch

A tsunami watch is issued to alert emergency management officials and the public of an event which may later impact the watch area. 

The watch area may be upgraded to a warning or advisory - or canceled - based on updated information and analysis. 

Therefore, emergency management officials and the public should prepare to take action. 

Watches are normally issued based on seismic information without confirmation that a destructive tsunami is underway.

Tsunami Advisory

A tsunami advisory is issued due to the threat of a potential tsunami which may produce strong currents or waves dangerous to those in or near the water. 

Coastal regions historically prone to damage due to strong currents induced by tsunamis are at the greatest risk. 

The threat may continue for several hours after the arrival of the initial wave, but significant widespread inundation is not expected for areas under an advisory.  

Appropriate actions to be taken by local officials may include closing beaches, evacuating harbors and marinas, and the repositioning of ships to deep waters when there is time to safely do so. 

Advisories are normally updated to continue the advisory, expand/contract affected areas, upgrade to a warning, or cancel the advisory.

Tsunami Information Statement

A tsunami information statement is issued to inform emergency management officials and the public that an earthquake has occurred, or that a tsunami warning, watch or advisory has been issued for another section of the ocean. 

In most cases, information statements are issued to indicate there is no threat of a destructive tsunami and to prevent unnecessary evacuations as the earthquake may have been felt in coastal areas. 

An information statement may, in appropriate situations, caution about the possibility of destructive local tsunamis. 

Information statements may be re-issued with additional information, though normally these messages are not updated.  However, a watch, advisory or warning may be issued for the area, if necessary, after analysis and/or updated information becomes available.


Tsunami warning centers message suite 20081

Warning Inundating wave possibleFull evacuation suggested

  • Issued when forecasted or observed amplitude is over 1.0 m or procedures

  • call for an immediate warning based on earthquake parameters

    Watch Danger level not yet knownStay alert for more info

    Issued to provide an early alert for areas that are distant from the wave front, but

    may have danger

    Advisory Strong currents likely Stay away from the shore

  • When forecasted amplitudes are in the range 0.3 - 1.0 m, or observed amplitudes

  • arein the range of 0.4 - 1.0 m.

  • When inundating waves have lessened and are dangerous in or near water fronts

  • only

  • When procedures call for an immediate advisory based on earthquake parameters
