Pacific Tsunami Warning Center Complex, Kaneohe, Hawaii, USA - November 5, 2011
1. Various of waves on coastline of Hawaii
2. Wide of Pacific Tsunami Warning Center Complex
3. Mid of Pacific Tsunami Warning Center main building
4. Pan from sign to staff monitoring equipment at centre
5. Set up of geophysicist Gerard J. Fryer at work
6. SOUNDBITE (English) Gerard J. Fryer, geophysicist, U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA):
"If the earthquake is under the ocean and shallow and big, then we'll issue a warning."
7. Close of real expansion warning put in place because of a M7.4 earthquake which occurred in the Mermadec Islands Region
8. Monitor indicating status of a real expanding warning
9. SOUNDBITE (English) Gerard J. Fryer, geophysicist, U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA):
(Describing expanding warning as seen on a monitor. The simulation was for a M8.1 earthquake)
"So this is where the tsunami is right now. This is where it will be in three hours and this is where it's going to be in six hours. So everywhere within the three hour limit would be in a warning. Here is Hawaii. Hawaii would right now be in a watch. It's actually going to take 3hours and 45 minutes before it reaches Hawaii"
10. Mid of geophysicist at computer, testing reception data from seismometers worldwide
11. SOUNDBITE (English) Gerard J. Fryer, geophysicist, U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA):
"Obviously the first thing you do is protect yourself from the earthquake - excuse me" -
( Fryer interview interrupted because bleeper signalling an alarm that a M5.3 earthquake just occurred in South America)
"We have an earthquake in South America."
12. Mid of monitor showing location of real earthquake and announcing location and magnitude with computerised voice
13. Pan across geophysicists taking readings coming in from different seismometers from the South American M5.3 earthquake
14. SOUNDBITE (English) Gerard J. Fryer, geophysicist, U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA):
"We send out those messages electronically and we'll usually send them out within about 7 or 8 minutes of the earthquake".
15. Various of screen showing seismometer reading coming in from different locations for a real M.7.4 earthquake. Readings are offset from each station because of the time it takes the earthquake to travel from the location of one seismometer to another
16. SOUNDBITE (English) Gerard J. Fryer, geophysicist, U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA):
"It turns out that earthquakes are not very efficient at generating tsunamis. Not much of the earthquake energy gets into the water so it takes a pretty big earthquake to generate a tsunami that's of any consequence at all."
17. Close of monitor showing noise data coming in from many seismometers worldwide in normal conditions.
18. SOUNDBITE (English) Gerard J. Fryer, geophysicist, U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA):
"Once you get into the magnitude 9s it's a no-brainer, you just issue a warning."
19. Close of monitor showing global map of recent earthquake activity
20. Monitor showing location of seismometers around the world
21. Various of Fryer and other staff monitoring data
22. SOUNDBITE (English) Gerard J. Fryer, geophysicist, U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA):
