| Seismologists don't know - and that makes them nervous |

| Mumbai: Unusual events "unheard of in the history of seismology" have been recorded in the Andaman and Nicobar islands, with more than 120 such events being recorded in the last one month, according to seismologists. The seismology department of the Bhabha Atomic Research Centre and the Earth Sciences Department of the Indian Institute of Technology here have recorded over 120 such unusual events in the islands following the December 26 earthquake measuring 8.9 on the Richter scale that triggered tsunamis which wreaked havoc in several parts of the country. Of these events recorded at BARC's Gouribidnur station in Karnataka, at least over 33 events were above 5 on the Richter scale, they said, adding "this is unusual and alarming as large amount of energy is being released so frequently." Eleven events with surface wave of magnitude 5, indicating large amount of energy close to Nicobar Islands was also recorded, the seismologists said. "Since yesterday, 16 events which range from 5.2 to 5.8 on the Richter scale have been recorded," they said. "Whether these events are foreshocks or aftershocks - it is not clear, and has to be taken up seriously and the data analysed as fast as possible," the scientists said. "Both strike slip and dip slip are taking place simultaneously and these factors have to be taken very seriously both by scientists and authorities," they added. |

| #22 Two years ago I finally got to see Mount St. Helens. Since it erupted in 1980 I've been fascinated by it, read everything I could get my hands on and studied every picture. But up close and personal, that thing is awesome-- I just found myself speechless. Tectonic volcanism may not hate us, but it sure has a bad temper. |

| #21 IMHO - it doesn't hate us - we just don't matter, kinda like my relationship with my first wife |

| #20 Tectonic volcanism; why does it hate us? |

| #19 When I was in USGS earthquake research in the early 70s we clocked er measured the San Andreas fault at 30 mm of regional strike slip per year. On Roberta Drive in Woodside, S of San Francisco, there was a 3' dia redwood stump straddling the fault that got split. The west side went 12 feet further north. That is ALOT of pent up rage. Seismic zones: why do they hate us? |

| #18 with my conversations with the distinguished Mr. Shipman, it is a deliberate affectation, one he returns. heh heh |

| #17 Frank G, your starting to sound like Muck. It's a phenomanon I've noticed on other blogs. Muckspeak is slowly taking over. |

| #15 The India Plate is currently moving northeast at 5 cm/yr (2 in/yr), while the Eurasian Plate is moving north at only 2 cm/yr (0.8 in/yr). This is easy, the answer is Atlanta. |

| #14 The India Plate is currently moving northeast at 5 cm/yr (2 in/yr), while the Eurasian Plate is moving north at only 2 cm/yr (0.8 in/yr). This is causing the Eurasian Plate to deform, and the India Plate to compress at a rate of 4 mm/yr (0.15 in/yr). So its official, both India and China are getting smaller. |

| #13 Himalayas are generally getting taller at a rate of over 1 cm a year. |

| #12 Are the Himalayas getting taller or shorter? |

| #10 could be - Occams' Razor sez it's Allan, still pissed off the mooselimbs aren't listening to his demand they quit killing and SHAPE THE FUCK UP, DAMMIT! |

| #9 Could it be that giant tsunami - quake maker Isreal and the US are testing. You know the one that caused the tsunami in Indian ocean ? |

| #8 Maybe it's a SUPER-VOLCANOE! You know, like the one which formed Yellowstone National Park! |

| #7 Cthulhu? LOL - well the moon-worshipper swould have found someone more to their tastes and a little closer to home |

| #6 We're talking tectonic plates here, folks. We are talking megatons of matter. Moving them around comes with the territory. Earthquakes happen when they move. Sheesh! Be thankful it's not an asteroid headin' our way, that could REALLY lower property values far and wide. |

| #5 The stars are almost right, it is just Cthulhu stiring in R'lyeh. |

| #4 Still waiting for the usual LLL suspects to explain how seismic activity deep in the earth is caused by "global warming'.... You'll notice I'm not holding my breath. |

| #3 Actually, if in fact both strike and dip slips are happening simultaneously, that means a whole LOT of energy is being released there - major plate movements, making many day to day earthquakes look puny. That part of the world may be in for a rough geological ride for a while. |
