It appears that the floating debris from the earthquake and tsunami in Japan last year is reaching North America sooner than expected.
It appears that the floating debris from the earthquake and tsunami in Japan last year is reaching North America sooner than expected.
I got a laugh from the last two sentences of this story. The early arrival of “more than 200 bottles, cans, buoys and floats” from Japan was immediately turned into a crisis that required government intervention.
With debris making landfall sooner than predicted, U.S. lawmakers have started to question whether the government is truly prepared. “Many people said we wouldn’t see any of this impact until 2013 or 2014, and now ships and motorcycles and this various debris is showing up and people want answers,” U.S. Sen. Maria Cantwell, D-Wash., said.
And if the debris was taking longer to get here? Cantwell would then argue we need to spend more money to track it more precisely. By her standards, no matter what happens, government has got to get bigger.

Spectacular video of a volcano eruption in Japan yesterday.
Sakurajima Volcano, which scientists have on alert since last year, erupted in Japan yesterday. Spectacular video below the fold.
This is not the big eruption that scientists are expecting, only a preliminary.

New simulations suggest that the magnitude of tsunamis predicted to hit Japan have previously been underestimated.
New simulations suggest that the magnitude of tsunamis predicted to hit Japan have been significantly underestimated.
The difficulty here is that these predicted giant tsunamis are still expected to be very rare events. It is thus unclear what is more practical, to build things at great cost so that they can survive these rare events, or to live with the risk and rebuild each time after disaster strikes.

The manslaughter trial of six scientists and one government official continued yesterday in Italy over their reassurances to the public prior to a deadly earthquake in 2009.
The manslaughter trial of six scientists and one government official continued yesterday in Italy over their reassurances to the public prior to a deadly earthquake in 2009.
Guido Bertolaso, former head of the Department of Civil Protection and De Bernardinis’s direct superior, had not been indicted and was originally expected to appear as a witness. But a few weeks ago a wiretap revealed that he had apparently set up the meeting to convey a reassuring message, regardless of the scientists’ opinion. He also seemed to be the source of the “discharge of energy” statement. He thus found himself under investigation and, at the beginning of the hearing, he was officially notified that he too may soon be formally indicted for manslaughter.
Bertolaso was asked by the prosecutor to explain that telephone conversation. He defended himself by saying that by defining the meeting as a “media move”, he was not trying to downplay risks but rather to put some order into the contradictory information that was reaching the citizens in those days. In particular, he referred to Giampaolo Giuliani — a laboratory technician and amateur seismologist who was alarming the population with claims that a major shock was coming — and to a newspaper article that had misquoted some Civil Protection experts and stated that the shocks would soon be over. The meeting, he said, was meant to make clear that both were wrong and that no deterministic prediction could be made. [emphasis mine]
This increasingly appears to be another case of science being corrupted by politics.

Underground again today
Posting will be light today, as I am joining University of Arizona PhD student Sarah Trube and several other Arizona cavers on a cave trip to collect water samples in a southern Arizona cave. This is in connection with research Sarah is doing to analyze the chemistry of cave dripwater and how it leads to the formation of cave speleothems. Moreover, she is tracking water flow and attempting to link it to climate and weather variations over time.
I noticed Sarah’s water collection equipment on my first Tucson-area cave trip back last January. In one case she had attached a tube to the bottom of a stalactite which fed the dripwater into a bottle. In another case she placed glass plates on top of stalagmites to allow the dripwater to drip onto the plate and then evaporate. Last month I joined her on one of her collection trips, where she gathered glass plates for later analysis in the lab. Though the plates had not been in cave more than a few months, you could easily see a thin layer of calcite deposit on their surface.
Below the fold is an image of Sarah gathering dripwater during an earlier trip.

What is this stuff?
The uncertainty of science: In this week’s release of images from Mars Reconnaissance Orbiter, the science team posted the image on the right and asked, “What is this stuff?”
Here’s a hypothetical geologic history that might explain this scene: layered sediments were deposited by water or airfall (including volcanic pyroclastics). A crudely polygonal patterned ground was created by stresses in the sediments, and groundwater followed the fractures and deposited minerals that cemented the sediments. This was followed by perhaps billions of years of erosion by the wind, leaving the cemented fractures as high-standing ridges.
Of course, this story is almost certainly incomplete if not totally wrong.
