As a result, a tsunami warning has been issued for Hawaii, Polynesia and Tonga, with waves expected to reach Hawaii at 11:19 a.m local time (4:19 p.m. EST). A tsunami advisory has been issued for California, while tsunami warnings have been issued for 53 countries in total, including Australia and New Zealand.We’re currently tracking the coverage online with a combination of live streams from local TV stations, official information from the NOAA and updates from Twitter and real time search.
1. Live streaming video (Ustream) – Ustream is helpfully providing TV coverage from local channels in Chile and Hawaii. We’ve aggregated the most relevant channels in a blog post.
2. Twitter hashtag #tsunami – Twitter users are tagging updates with #tsunami, and Twitter search is proving extremely useful for news tracking. Remember that Twitter’s advanced search lets you find updates posted from specific places – Chile or Hawaii, for instance.
3. Google Realtime search “Tsunami warning” – Google’s realtime search combines news results with postings from Twitter, blogs and other realtime sources. “Tsunami warning” delivers relevant results, but obviously tweak your search terms if you’re looking for something more specific.
4. NOAA Pacific Tsunami Warning Center – The PTWC provides a collection of resources for those tracking the tsunami, including maps of those areas where tsunami warnings and advisories have been issued.
5. NOAA’s Tsunami.gov – Tsunami.gov is the NOAA’s official tsunami site, providing links to their local warning centers. However, we’re getting limited uptime today, presumably due to heavy traffic. Using the other sources above may keep this site available to those who most need it.
