AB: Following the tragic Indian Ocean Tsunami of 2004, the Richard Hagemeyer Pacific Tsunami Warning Center (PTWC) has dramatically enhanced its capabilities. With improved communications PTWC now ingests seismic data from almost all broadband stations of the Global Seismographic Network and will soon add many stations from the International Monitoring System. As data sources are increased PTWC's response time to any earthquake declines; for most earthquakes the center now gets out an initial message in about 12 minutes. With 24-hour staffing, that performance is maintained around the clock. Direct measurement of tsunamis has been improved through communications upgrades to coastal tide gauges by NOAA and other collaborators in the Pacific Tsunami Warning System, and by the NOAA deployment of DART instruments throughout the world's oceans. In addition to providing warnings for the Pacific (with the exception of Alaska and the west coasts of the U.S, and Canada, which are the responsibility of the West Coast and Alaska Tsunami Warning Center), PTWC also operates as an interim warning center for the Indian Ocean (a task performed in collaboration with the Japan Meteorological Agency) and the Caribbean. PTWC also operates as a local warning center for the State of Hawaii. In Hawaii, the installation of new seismometers again means a continuous reduction in PTWC's response times. Initial assessments of local earthquakes are routinely accomplished in less than five minutes, and the first message for the Kiholo Bay Earthquake of 2006 was issued in only three minutes. With the development of the Hawaii Integrated Seismographic Network, in collaboration with the U.S. Geological Survey, the goal is to reduce the time for tsunami warnings to under two minutes for any earthquake in the Hawaiian Islands.
