8.8 Chilean quake opens “Red Cross Month”
Posted on | March 1, 2010 | No Comments
MARCH has been known as “National Red Cross” month since President Franklin Delano Roosevelt issued the declaration in support of Red Cross efforts to raise funds for World War II services. On the event’s 67th anniversary, the earthquake in Chile underscores the importance of emergency relief services. Nothing is more urgently required following an earthquake than fresh, potable water. To help get it to Chilean quake survivors, click here to be taken to the American Red Cross. Donations of $10 or more are as easy to make as a purchase on Amazon.

High good, low bad: Mead in February 2010

Between 96 and 112 men died in the construction of Hoover Dam, depending on how you count the deaths (from the time of the dam’s commission in 1922 or from the start of construction in 1931).
Did they die to make the desert bloom, or because the massive federal works project offered jobs job during the Great Depression? Whether they took one for a buck or a bloom, ever since the dam’s completion and the filling of Lake Mead behind it in 1935, the captured water has gone to both desert farming in California and Arizona and a massive Southwestern housing boom.
The upshot has been an ever-swelling population dependent on a naturally varying supply of water. Since 2002, that variation has been toward a dry cycle, leaving sunbelt suburbs and farms in a Darwinian struggle for water. Moreover, the specter of climate change suggests a starkly drier future. The steadily descending elevations of Lake Mead during the last decade are laid out after the jump. The federal Bureau of Reclamation reports that Mead is at 46% of capacity and the entire Colorado River system at 56%.

Click on the image to be taken to the National Oceanic and Atmospheric Administration's Center for Tsunami Research to see how models calculate earthquake reverberations in the ocean. The models allow time for evacuation alerts. NBC reported that "tsunami waves began hitting the Hawaiian islands at "exactly the time scientists predicted."
The tsunami raced across the Pacific Ocean at the speed of a jetliner after the quake hit Chile hours earlier. — “Quake-triggered tsunami rushes ashore in Hawaii,” AP / Seattle Times, February 27, 2010*
… the sea level rose almost three feet at Hilo, surging and receding numerous times at intervals of about 20 minutes. — “Tsunami waves crossing the Hawaiian Islands,” NBC Hawaii News Now, February 27, 2010. Click here for time-lapse video.
… if one plate dives under the other, which is probably what occurred early Saturday off the coast of Chile, it will displace “a huge column of water.” — Solomon Yin, director of the Hinsdale Wave Research Laboratory, Oregon State University, ”Tsunami magnitude difficult to predict,” Los Angeles Times, February 28, 2010**
The Dry Garden: Protecting the Pacific

What, you might ask, does the ocean have to do with gardening? In California, Orange County landscape designer Douglas Kent would reply: Everything. All the rain that we don’t catch during the winter and all of the irrigation spilled into the streets from our sprinklers in the warm months end up as storm water. “Water running into the ocean is not inherently harmful,” Kent writes in his new book Ocean Friendly Gardens. “It is the stuff attached to it and the stuff it picks up on the way to the ocean that is. Fertilizers, pesticides, oils, cleaning solutions and organic debris all run off a landscape.”

Nevada head of Natural Resources: I am not carrying the water for SNWA

Updated 10.16am 3/1/2010. The Las Vegas Review-Journal reports that the Nevada Legislature will send the proposed water bill to committee before disbanding its special session today. Governor Jim Gibbons may recall legislature for a vote on it once the bill is out of committee.
Governor Jim Gibbons’ instruction to the Nevada legislature to amend state law in a way that would retroactively legalize water awards made since 1947 will not render moot a recent state Supreme Court decision that threatens the future of a controversial Las Vegas pipeline project, a senior state official said today.
Rather, Allen Biaggi, head of the Nevada Department of Conservation and Natural Resources, insisted that the Governor’s instruction has been accompanied by proposed language that excludes from amnesty any awards made to the Southern Nevada Water Authority.
However, as pipeline protestors read the same document, they say they are better off staying in the courts and out of legislature.
