        seismic events;
            (4) identify tsunami sensors, such as those developed by 
        the National Oceanic and Atmospheric Administration and 
        deployed under its Deep Ocean Assessment and Report of Tsunamis 
        Project, or other appropriate ocean-based sensors, that can be 
        deployed to detect potential tsunamis generated by any type of 
        disturbance, including earthquake, underwater landslide, above 
        water landslide, eruption of an explosive volcano, and meteor 
        impact;
            (5) identify the number and location of such sensors that 
        must be deployed throughout the Atlantic, Indian, and Pacific 
        Oceans, and associated seas, and any other bodies of water of 
        concern, to provide a system offering complete global coverage 
        for detection of a tsunami, taking into consideration and 
        coordinating with any regional systems in place or under 
        development through other nations in the affected regions;
            (6) procure and deploy such sensors;
            (7) establish the measurement system, forecast system, and 
        communication system and infrastructure needed to receive and 
        process the signals generated by such tsunami sensors, by 
        building on existing infrastructure at existing Centers of the 
        National Oceanic and Atmospheric Administration, such as the 
        Pacific Tsunami Warning Center and West Coast and Alaska 
        Tsunami Center; and
            (8) disseminate tsunami forecasts and warnings as necessary 
        to all potentially affected nations.
    (b) Report to Congress.--Not later than 180 days after the date of 
the enactment of this Act, the Secretary of Commerce shall submit to 
Congress a report on the progress made in carrying out the requirements 
of subsection (a).

SEC. 3. INTERNATIONAL CONFERENCE ON GLOBAL TSUNAMI DETECTION AND 
              WARNING.

    (a) Sense of Congress on Convening Conference.--It is the sense of 
Congress that the President, in consultation with the leaders of 
nations described in section 4(a)(1), should undertake to convene, 
within 180 days after the date of the enactment of this Act, an 
international conference on global tsunami detection and warning for 
the purposes of--
            (1) supporting the common objective of such nations of
