Re: Now the US is warning Japan -- keep buying those Treasuries otherwise next time it's the tsunami... LOL... I don't blame the US for THIS earthquake. Keep in mind that, while tsunamis are a common feature in the Pacific Ocean, it's quite uncommon in the Indian Ocean: Message 20945076 Besides, I don't think the US need to strong-arm Japan into sticking by the US: the rise of China is enough to bring the US and Japan together.

Slowly but surely, the truth on the nuclear tsunami seeps across the blogosphere... you'll be the only party-pooper left, Searle! View Comments: doc 1. A one megaton bomb can measure 7.5 on the Richter scale. Note the use of "can measure". It really matters where the bomb is placed. If, for example, you drop a bomb on a fault line, or use a "bunker buster" that digs into the ground, you might wind up with a bit more or less force. From: archaeology.org Thus 10 megatons could measure 8.5 on the Richter scale, and 30 megatons would be necessary to cause a 9.0. It could have been easily caused by a few cold-war nukes. 2. The Richter scale (ML) wasn't exactly used to measure this quake, since the frequency was so low and the compression statistics were correspondingly crappier. neic.usgs.gov The monitoring in this region wasn't exactly stellar. It's a big source of debate right now in India (who's gonna pay for better monitoring). 3. My request to purchase satellite picutres of the earthquake from digitalglobe.com got this response: "We do not have imagery over the ocean where the tsunami originated. However, we do have imagery over the Asian regions affected by the tsunami with numerous resources available on our website for obtaining or observing this imagery listed below." 4. "The Indian Ocean ... had not had a tsunami in recorded history" the.honoluluadvertiser.com 5. Can a nuclear explosion cause an earthquake? "On January 19, 1968, a thermonuclear test, codenamed Faultless, took place in the Central Nevada Supplemental Test Area. The codename turned out to be a poor choice of words because a fresh fault rupture some 1200 meters long was produced" earthquake.usgs.gov 6. Estimations of focal depth of the Northern Sumatra quake is reported at 30 KM neic.usgs.gov However, you have to read the fine print. neic.usgs.gov If the depth of an event is not satisfactorily determined by the data, it is held to a default depth, and the Location Quality shows "depth fixed by location program." If you look at the phase data, you see only a handful of broadly varying estimates of focal depth, averaging 15KM. That's why the data was not used for the location estimate. Instead, a geologist estimated the depth at 30KM based on fault data because, logically, an earthquake cannot originate from the ocean floor. Note: The ocean depth at that point is 1.3KM += .5 KM topex.ucsd.edu Deep sea submersibles routinely explore at that depth, so water pressure preventing a proper explosion would not be an issue. documentroot.com Say uncle?

THAT CLINCHES IT.... CHAPTER 3 EFFECTS OF NUCLEAR EXPLOSIONS SECTION I - GENERAL [...] 310. Shock Waves in Other Media. a. In surface and subsurface bursts, a sizable portion of the yield is transmitted in the form of ground or water shock waves. In the case of a surface burst on land, a crater is formed at ground zero, the size of which depends primarily upon yield. Relatively little damage beyond a distance of approximately three crater radii will occur due to ground shock. Most damage will be due to the accompanying air blast wave. In subsurface bursts the crater will be formed either by ejection of material as in a shallow explosion or by the collapse of ground into the cavity formed by a deeper explosion. Since the overpressure in a ground shock wave decreases very rapidly with distance, shock damage will again be confined to a region close to the point of detonation. b. Ground shock waves will also be induced as a result of an air burst. If the overpressure in the blast wave is very large, the ground shock will penetrate some distance into the ground and may damage underground structures and buried utilities, etc. c. Because of the density and relative incompressibility of water, shock waves in that medium have very high peak overpressures and velocities of propagation. The peak overpressure at a distance of 1 km from a 10 Kt underwater burst is approximately 6080 kPa (60 atm (atmospheres of pressure)), while the peak overpressure in air at the same distance from an air burst is only 111.4 kPa (1.1 atm). The resulting surface waves at this distance will be approximately 10 m in height. The shock front will also travel at approximately five times the speed of the blast wave in air. Severe damage to naval vessels may result from the shock wave produced by an underwater or water surface burst. Although the major portion of the shock energy is propagated in the water, a significant amount is also transferred through the surface as a typical air blast. This blast wave could probably be the principal source of damage to land targets if the explosion occurred in a coastal area. fas.org For the sake of clarity, let's emend the tagline: This TSUNAMI could probably be the principal source of damage to land targets if the explosion occurred in a coastal area.
