Eventually debris from Japan will arrive at Pacifica's shore.

We may need more than Pacifica Beach Coalition for this one.
 
From Silicon Valley Mercury News, 7/4/11.  "Millions of tons of debris that washed into the ocean during Japan's catastrophic earthquake and tsunami in March -- everything from furniture to roofs to pieces of cars -- are now moving steadily toward the United States and raising concerns about a potential environmental headache. Scientists using computer models say the wreckage, which is scattered across hundreds of miles of the Pacific Ocean, is expected to reach Midway and the Northwestern Hawaiian Islands by next spring and beaches in California, Oregon and Washington in 2013 or early 2014.

"Can you imagine San Francisco put through a shredder? A big grinder?" said Curtis Ebbesmeyer, a Seattle oceanographer who has studied marine debris for more than 20 years."The area north of Tokyo was basically shredded. We are going to see boats, parts of homes, lots of plastic bottles, chair cushions, kids' toys, everything." The debris is moving east at roughly 10 miles a day, and is spread over an area about 350 miles wide and 1,300 miles long -- an area roughly the size of California -- Ebbesmeyer estimates, with the leading edge approaching the international date line.

While lots of the material will break up and sink, some will not, he said. "I've seen pieces of wood float for 20 or 30 years," he said. "I have Jeep tires with wheels that floated for 30 years. Things float a lot longer than you think."  Complicating the issue, nobody knows for sure the exact area where the debris is spread or its density. And nobody knows what is still floating, what has sunk, or what may be lurking just below the surface. That's because estimates are based on computer models of currents and winds, rather than actual observations from scientists in boats and planes. After ships with the Navy's 7th Fleet reported and photographed the debris, researchers with the National Oceanic and Atmospheric Administration (NOAA) in Hawaii tracked the refuse with satellites for a month after the March 11 quake and tsunami."  computer modeling and more....
