Proposed Tsunami Network Systems

as of 11/04/05







    Our class has discussed the possible tsunami network systems that will make warning and evacuation, in the case of a tsunami most efficient.

One of the possible tsunami network systems that were discussed, Network System A is summarized in the flow diagram below.

Another possible network, Network System B is explained in the following flow diagram.

The advantages and disadvantages of the differences in these proposed network systems still need to be analyzed.

        In the event of a tsunami, in other words, when the DART II system triggers event mode, a critical difference exists between the operation of  the first network system A and the second network system B.
        Network system A, consists of the buoy sending data to the warning centers to have scientists analyze and verify that this data is reliable and that a tsunami will definitely occur near a certain area. The advantage to this system is that it will in the least significantly minimize, if not eliminate the possibility of a false alarm, which if occurs could diminish the effectiveness of the entire warning system. 
       On the other hand, network system B, consists of the buoy not only sending data to the warning centers immediately after a tsunami is detected, but to simultaneously trigger a warning of the possibility of a tsunami. Once it is triggered a warning of the possibility of a tsuami will be issued to the community through the tsunami warning system, which includes but is not limited to: sirens and radios. In order to prevent the attitude towards a false alarm, the ring of the siren, the message on the radio and other communication systems will only warn people that there is a possibility of a tsunami hitting their area. Thus it will be a lower level of warning than if it is verified that  a tsunami will hit.  Since the buoy's data still goes to the warning center, the existence of a tsunami can be verified, and thus the level of the warning is increased. The advantage to this system is that all operations will have more time, (a minimum of 5 more minutes) to prepare in the case that it is a real tsunami. The disadvantage to this system is that if the lower level of warning is frequent, or too frequent, the regard for the warning could be taken lightly by the people and thus decrease the efficiency and purpose of the warning system. We must still answer if it is possible to have this extra time without creating this apathy towards the warning system.

    Another problem with these network systems consists involves the communication of a tsunami warning to the governments of Peru, Micronesia and other nearby countries. If there was a law in place that guaranteed the tsunami warning center to issue a warning directly to the people in the case a tsunami was detected, with not much but notifying government simultaneously, then the network system will be much more time efficient.  Of course, this idea still needs to be modified in a way that would be acceptable to the governments of Peru and Micronesia. 
    All these network systems assume that if an earthquake caused a tsunami, the magnitude and location of the earthquake would be sent immediately to tsunami warning centers.
