| Red alert after Indonesian volcano erupts |
| 2010-08-29 |
| Sinabung is 75 Ks north of the Toba caldera, and whatever caused the catastrophic Toba eruption may well be active under the Sinabung volcano. |

| #11 Go Nature. Hit back. Lets have a big supervolcano eruption, god knows there are too many people on this planet swarming like ants and breeding like flies. Wipe us out down to a small and manageable number please. Come on TOBA!! |

| #10 "SINBUNG VOLCANO" > FYI RBurgers there were PRE-ERUPTION, POST-MIDNITE OFF-SHAPED EM SKYBALLS = "OBLONGS" OF LIGHTS INCLUD AURORAE oer Guam-WESTPAC in the general strategic direction of Indonesia + SE ASIA. Also, VERY SLIGHT TREMORS thus far. LOOKS LIKE MOTHER EARTH + SUN LIKE TO FOLLOW THE USAF + USDOD-DARPA'S LEAD IN DOING EVERYTHING COVERTLY WHILE PEOPLE ARE TRYING TO SLEEP. |

| #9 #7 thank you for the good info. "MICROPLATES" > I can believe it, as the MINI/MICRO-FAULT LINES I've detected just here in Hagatna + around Guam make for really complex patterns, BOTH BEAUTIFUL + SCARY AT THE SAME TIME. |

| #8 In the new model, the researchers were able to resolve the largest fault zones, creating a mesh with a resolution of about one kilometer near the plate boundaries. Included in the simulation were seismological data as well as data pertaining to the temperature of the rocks, their density, and their viscosity—or how strong or weak the rocks are, which affects how easily they deform. That deformation is nonlinear—with simple changes producing unexpected and complex effects. "Normally, when you hit a baseball with a bat, the properties of the bat don't change—it won't turn to Silly Putty. In the earth, the properties do change, which creates an exciting computational problem," says Gurnis. "If the system is too nonlinear, the earth becomes too mushy; if it's not nonlinear enough, plates won't move. We need to hit the 'sweet spot.'" |

| #7 Just for JOE! (because the Tonga is closer than most to his area) New view of tectonic plates After crunching through the data for 100,000 hours of processing time per run, the model returned an estimate of the motion of both large tectonic plates and smaller microplates—including their speed and direction. The results were remarkably close to observed plate movements. In fact, the investigators discovered that anomalous rapid motion of microplates emerged from the global simulations. "In the western Pacific," Gurnis says, "we have some of the most rapid tectonic motions seen anywhere on Earth, in a process called 'trench rollback.' For the first time, we found that these small-scale tectonic motions emerged from the global models, opening a new frontier in geophysics." One surprising result from the model relates to the energy released from plates in earthquake zones. "It had been thought that the majority of energy associated with plate tectonics is released when plates bend, but it turns out that's much less important than previously thought," Gurnis says. "Instead, we found that much of the energy dissipation occurs in the earth's deep interior. We never saw this when we looked on smaller scales." |

| #5 where are the UN scientists to add up all the carbon emissions? I bet it gives off the carbon of 3000 Australias, making all our expensive efforts at carbon reduction futile, meaningless waste of money. But you can't hobble the "rich" world and empower the third world by blaming a volcano.... no black balloons for you Hope the supervolcano goes off and reduces the global population down to say 100 million. That is enough for sure. Then if we all agree to just have 2 kids each the world will be a much nicer place. |

| #4 Let me see. Flood in Pakistan. Earthquake in Iran. Volcano in Indonesia. Do I detect a pattern? |

| #3 Hmmmm, dormant for centuries....well, guess what. On the geologic timescale, that's about the time of a sneeze. Or maybe half a one. Lots of volcano's of late. If this keeps up, with enough ash being ejected we may see some rather serious weather effects. Ash is the major concern so far as long range effects of a volcano, the other dangers are primarily local in nature. |

| #2 The panorama from Gundaling Hills is especially beautiful in this afternoon. You can see the whole city, its surrounding orchards, and the crater of Mount Sibayak, a volcano that has been dormant for centuries. To the west is Mount Sinabung (another dormant volcano), while the Karo plains lie on the south. |
