Earthquake and Tsunami Prevention 101
Friday, December 28th, 2007I’m addicted to the Science Channel. The topic of interest tonight was tsunamis. After the one in Indonesia that killed a quarter million people it should be of interest to everyone who lives on a coast somewhere. There are many shifting plates around the world known for their activity that can cause earthquakes. I had no idea how many there really are. There is a Eurasian-African plate, Indian Australian plate, the Alpine plate, Caribbean plate, a lot of plates for a lot of earthquakes.
Australia is particularly concerned. It seems the most likely place a tsunami will hit as it has before is the East Coast of Australia where sits Sydney. There is a huge public beach there with thousands of beachgoers in the summer season. A simulated video showed how a Tsunami like that in Indonesia would travel up an inlet there and really cause trouble because the coastline is lined with boulders. Imagine a wall of water coming at you full of boulders. If the water doesn’t kill you the debris does.
Australia has suffered two large tsunamis near Sydney and a bunch of small ones in the past. Earthquakes along the Alpine Fault next to New Zealand are to blame. Earthquakes there happen every 500 years and guess what’s overdue? It was stated that just because it hasn’t happened does not mean it’s not going to. It means it will really be big when it does. Sounds like giving birth doesn’t it?
Hawaii has been hit by tsunamis in the past also. But now Hawaii has the NOAA Tsunami Warning Center to give notice as soon as possible. But will it be soon enough? Right now Dr. Stephen Hickman, a scientist with the U.S. Geological Society is involved with drilling down and across the San Andreas Fault off of San Francisco in order to secure seismic meters there in an attempt to have the earliest warning possible of any and all earthquakes. I was reading more about this project on the Southern California Earthquake Center website and the author, part of a film crew, says he was standing on the drilling platform of the SAFOD or San Andreas Fault Observatory at Depth project when an earthquake hit. Now that’s reporting firsthand. It was a 6.0 and the comment was that this was probably ‘the most well-recorded earthquake in history.’
It’s an interesting and humorous story, and quite a fluke that the author was actually there on top of the quake shaking violently on the drilling platform. This is quite a new and innovative project, but in the end may save millions of people if it can forecast big and small, upcoming quakes, and broadcast threats of any resulting tsunamis. I wonder how or who is placing those seismic meters in the tunnels? Considering what happened, not a good job to have. Kind of like putting the first construction cone out on the highway.
