They're stable with no radiation leaks. No obvious changes at the troubled Fukushima units, which suffered serious complications after loss of power to the control systems and pure water circulating pumps, and had the secondary loop (salt water to cool the heat exchangers) pumps totally washed away by the March 11th Tsunami.

The warnings were saying possible 1 meter height. For people to have to get out at midnight perhaps with no power, run for higher ground must have been very traumatic. Fortunately there wasn't a significant tsunami. Reports say they quake started with vertical jolts, followed by a long period of intense horizontal shaking.

For energy released, the relationship is 10^1.5 or ~32x for each Richter magnitude step, although Richter magnitude isn't used as much anymore. Usually scientists use moment magnitude these days, which has the same relationship to energy. It makes sense that energy would equate to what you feel and how much damage occurs, but there are additional effects depending on the exact way the ground is displaced, what happens as the waves propagate from the focus to the place you are experiencing the quake, duration, frequency content, ground properties, etc.

      But by any qualitative measure anything over 7 (on either scale) is a big, potentially-damaging quake. Fortunately this one was off the coast like before, and the effects diminish with distance, so the cities in Japan won't experience as severe effects as the magnitude would imply if it were directly beneath the city. To put things in perspective, the 1995 Kobe earthquake was "only" a 6.8 on the moment magnitude scale, and "only" 7.3 on the JMA scale -- i.e. smaller than this aftershock.

      A number of people at uVic have I believe (can't recall the source material location offhand). The seabed in Indonesia is significantly different to that around Vancouver Island and the Strait of Juan de Fuca. However, at least one researcher disagrees:

      From http://library.lanl.gov/tsunami/ts274.pdf:

      To understand the threat to western Canada, it is important to understand the geological
      features off the coast of British Columbia. From northern Vancouver Island to northern
      California, the Cascadia subduction zone marks the boundary between the smaller offshore
      Juan de Fuca Plate that is sliding under the much larger North American Plate. The
      Cascadia subduction zone has the potential to generate very large earthquakes, with
      magnitude 9.0 or greater, if the fault ruptures over its entire area. The January 26, 1700,
      Cascadia earthquake produced a fault rupture with a length of 1000 km. This type of event
      is similar to the 2004 Indian Ocean Earthquake, were the fault ruptured along an estimated
      length of 1300 km. Interestingly, both subduction zones run predominantly in a north-south
      direction, thus having the potential to trigger major tsunamis in the east-west direction. For
      Cascadia, this means that tsunami waves would propagate towards Vancouver Island.
      Popular belief suggests that major nearby cities, including Vancouver, Victoria, Seattle, and
      Portland, which are located on inland waterways rather than on the coast, would be
      sheltered from the full brunt of a tsunami wave. Meanwhile, numerical modeling has shown
      that tsunami waves would travel around Vancouver Island through diffraction and impact
      Victoria and Vancouver significantly (Xie et al., 2007). This is consistent with observations
      following the 2004 Indian Ocean Tsunami, particularly on the west coast of Sri Lanka
      which was devastated by the tsunami as a result of wave propagation and diffraction around
      the island. Therefore, a megathrust earthquake along the Cascadia subduction zone has the
      potential to generate a major tsunami which would travel into the Juan de Fuca Straight,
      affecting communities along its shores.
      Understanding the tsunami hazard is a major challenge in the design of near-shoreline
      structures. However, hazard maps, which would provide inundation depths and velocities
      for design in the case of a tsunami with a given magnitude and a given return period, are
      currently not available. At present, numerical modeling is employed to provide expected
      inundation depths for a given earthquake. Xie et al. (2007) conducted numerical modeling
      of tsunamis generated from a Cascadia Fault earthquake to assess the potential tsunami risk
      for western Canada. A magnitude 9.0 earthquake, similar to the event of 1700, was assumed
      in their model. The numerical model TSUNAMI N2 was employed. The model estimated a
      maximum wave run-up of 25 m along the western shore of Vancouver Island, with an
      estimated arrival time for the first wave of 1 hour and 20 minutes.

      i'm a complete new york city bigot: i believe this is the best city on earth. however, i've been to vancouver twice, and both times i've been flabbergasted how awesome that city is. i would definitely and happily move there. and having worked at the world trade center until the morning of 9/11/2001, i'm not that put off by megadisaster anymore. except for the weird drug zombie town you have between chinatown and gastown. i don't know why you guys tolerate that stuff, its not like you're helping those sad sacks continue in that mode of existence

      maybe i've just had my ego tweaked, because within 10 minutes of landing, in the airport, in front of that big green stone boat thing with all the first nation gods, a first nation chick flat out picked me up and toured around the city with me the whole week just for the hell of it! no, it wasn't a con, no money was involved and i was poor anyways. it was pretty cool meeting these established first nation artists she knew well, taking in the first nation art scene, hanging out with all these first nation kids, as if i had been an old hand 10 years at it and not some dumb tourist. i lost touch with her, last i heard she was somewhere back up in the mountains with a kid. but damn you canucks know hospitality, that's for sure. or at least your first nation does!

      although, i actually sat in on a condo board meeting with my friend who owned a place there, and they were talking about a rash of recent attempted break ins, and out came all this anti-american commentary, that it had to be an american doing the break ins (not your drug zombies?). i think i laughed out loud at the guy who said something along the lines of "get them to sing the (whatever the canuckistan national anthem is), and if they can't do it, we've caught our culprit." good times, good times

    Though it's worth noting that magnitude scales really are orders of magnitude, it's also worth noting that even a "weak" earthquake can cause catastrophic damage. The Haiti earthquake was "only" a 7.0, but it killed approximately 300,000 people, which is about 10 times any estimate I've heard of the death toll in Japan. The difference is that the Haiti earthquake hit a stone's throw away from a major population center. In earthquakes, much as in real estate, location is everything.

  60. Re:Magnetic Pole moving by MickLinux · · Score: 1

    I'm more inclined to think that the magma flux normally creates hotspots (such as iceland or hawaii), but takes advantage of oceanic rifts to dump heat from nuclear reactions down below.

    But I'm inclined to think that *it* matches the tectonics, not vice versa.

    Iif you look at the sudden motion of India as Gondwana shattered (145 ma), and note that there are a huge number of craters from Tiera Del Fuego to South Georgia Island in a Shoemaker-Levy-9 style strike, and then map that over to Gondwana, I think it will become perfectly clear that low-angle asteroid strikes drive plate tectonics.

    Note, too, that *if* Shiva is an asteroid, then it would appear that it too struck India at the time of the Yucatan strike (65 ma) with a low-angle strike travelling N-NE, and opened the Deccan Traps -- but also drove India straight from its location then to its location now. Quite simply, the Deccan Traps are evidence of India being partially torn in two.

    Plate tectonics is a very low energy event (1/2 m v^2: For Australia, about 10 kJ. For the whole plate, about 45 kJ... similar to a big truck going 2 m/s) but a very high momentum event (p=m*v: For australia, 10x10^12 kg*m/s, for the plate, about 45x10^12 kg*m/s). Therefore, it takes momentum transfer, not energy transfer, to affect plate motion.

    So... basically the problem here isn't a change in magma flux. Rather, it might be that everything is converging on Hawaii (China, Australia, the North American Plate, and so on), and that makes the Ring of Fire a rather hot place to be.

    Or... the problem might be that instead of giving glory to God, we are gnashing our teeth and blaspheming Him. Maybe if we allowed our chastisements to change our hearts, the problems would cease.
