New PTWC Tsunami Products for Pacific to Start 1 October 2014

 

PTWCops IMG 8406 crop smlStarting 1 October 2014, the US NOAA Pacific Tsunami Warning Center (PTWC) will commence issuance of New Enhanced Tsunami Products for all Pacific countries, culminating a 7-year intergovernmental process coordinated by the UNESCO Intergovernmental Oceanographic Commission (IOC) through its Intergovernmental Coordination Group for the Pacific Tsunami Warning and Mitigation System (ICG/PTWS). PTWC will retire its Warning and Watch services, and begin issuing wave height threat forecasts to country National Tsunami Warning Centers, who will assess and issue Warnings using guidance from the PTWC, national, and other sources.

Most of the world's earthquakes and tsunamis occur in the Pacific Ocean and its marginal seas, an area spanning more than 20,000 kilometers east to west.  Over history, the Pacific has had 75% of the world’s fatal tsunamis, with 99% of those casualties from local tsunamis that struck within minutes. On average, the Pacific is hit by a locally damaging tsunami every year or two, and by a major Pacific-wide tsunami a few times each century. Over the past nine years (2005-2014), the Pacific witnessed six destructive and deadly tsunamis that placed Pacific countries in various levels of warnings for local and distant tsunamis. However, since the start of the international warning system for the Pacific in 1965, less than 1% of tsunami deaths have occurred in the far field, as compared to ~17% of tsunami deaths prior to 1965.

Indian Ocean-wide Tsunami Exercise (IOWAVE), 9-10 September 2014

 

24 countries of the Indian Ocean Tsunami Warning and Mitigation System took part in an End2End IOC smlinternational tsunami exercise on 9-10 September 2014. The exercise, coordinated by the UNESCO IOC under the leadership of Australia and Indonesia, tested the effectiveness of stakeholder communication flows, country readiness, and tsunami emergency procedures. IOWAVE14 was conducted in real time with the IO Regional Tsunami Service Providers (Australia, India, Indonesia) providing notification messages to country National Tsunami Warning Centers for two simulated scenarios, a M9.1 south of Java, Indonesia, and a M9.0 in the Makran Trench, south of Iran and Pakistan.
