Im in AL...not much of a nuclear event. As for the other things, they're most likey small. I think they said that tsunami was like a foot
hight...oh, so scary.
"Event happened at 02:20:00 on 17/08/2007: Had it come in daylight, the minitsunami that hit the Hawaiian Islands might have been noticeable at Hilo
and Kahului. But the biggest local wave generated Wednesday by an earthquake in Peru was only 27 inches high when it hit Hilo at 2:20 a.m. Thursday,
said Dailin Wang, a Pacific Tsunami Warning Center oceanographer. The center had issued an advisory at 2:20 p.m. Hawaii time Wednesday that it was
evaluating the potential threat from the 1:40 p.m. Pisco, Peru, quake. Although the earthquake measured 8 on the Richter scale, by 4:10 p.m. Wednesday
the Pacific Tsunami Warning Center advised that Hawaii would not get a significant tsunami from it, Wang said. "Hawaii was never in the warning
area," he said, just under an advisory. "We've got to balance between a real warning and a false warning," Wang said. The prediction was good,
Wang said, as wave measurements for Hawaiian islands on Thursday showed:
- Hilo had the largest wave at 27 inches. Additional tsunamis continued every 17 minutes for a day, though by noon Thursday the wave size had dropped
to 7 inches.
- Kahului's largest wave was about 23 inches.
- Honolulu Harbor's largest wave was only 3 to 4 inches.
- On Kauai, Nawiliwili Harbor's largest wave was 3 inches.
Thursday's tsunamis fell within the range of tidal fluctuation for Hawaii's harbors, Wang said. However, the larger waves would have been visible at
Kahului or Hilo because they moved in at 17-minute intervals - not gradually like a tide change, he said. However, Big Island Mayor Harry Kim said he
did not expect that anyone was at Hilo Harbor to notice. Hilo keeps a particular vigilance for tsunamis, having experienced a 46-foot wave April 1,
1946, and a May 22, 1960, tsunami that killed 61 people. "I have confidence in the PTWC (Pacific Tsunami Warning Center)," Kim said. "When they say
'Cancel it' (of the advisory) and put out an announcement to expect water-level fluctuations, I wasn't too concerned about it, because of the
hour" the waves were to reach Hawaii, Kim said. "We just say 'thank you' and go home.""
As for the nuclear event.
The Tennessee Valley Authority shut down one of three units at the Browns Ferry nuclear plant Thursday because water drawn from a river to cool the
reactor was too hot, a spokesman said. The nation's largest public utility shut down Unit 2 about 5:42 p.m. CDT because water drawn from the
Tennessee River was exceeding a 90-degree average over 24 hours, amid a blistering heat wave across the Southeast. "We don't believe we've ever
shut down a nuclear unit because of river temperature," said John Moulton, spokesman for the Knoxville, Tenn.-based utility. He said TVA would
compensate for the loss of power by buying power elsewhere. The utility announced earlier Thursday that it was imposing a fuel surcharge on customers
because of lower hydroelectric power production caused by drought conditions. Two other units at the plant were operating, as well as towers to cool
the water. But searing temperatures and a lack of cooler water in the upper part of the Tennessee River system made it too difficult to provide cool
water for all three reactors. There was no safety threat posed by the shutdown. Moulton said the average high temperature Thursday was 103 for five of
the largest cities in TVA's coverage area: Huntsville and Knoxville, Chattanooga, Memphis and Nashville in Tennessee. "It's the hottest in 20
years," he said.
He would not estimate when the unit would go back on line, saying it will depend on the weather. "Temperatures are supposed to moderate some, but it
will take a while for the river temperature to do that, too," Moulton said. He said demand for TVA power set a record 'Thursday but the figures
would not be available until Friday.
