I am not a scientist I was only giving a theory that it is possible that a underground nuke test could of caused the Asian disaster.
Why? Well most underground nuclear testing of nukes is difficult to detect and according to, the United States Secretary of Energy in 1993 the government disclosed in a report titled Radiological Effluents Released from United States Continental Tests, that the government conducted 204 previously top secret unannounced underground nuclear tests and simultaneous detonations which were never picked up by earthquake radars.
That is a fact the government itself says that those 204 underground nuke tests were secret and never detected by anyone which I would assume would include the Coast Guards earthquake radars. See
http://www.osti.gov/html/osti/opennet/document/jan97/prcfacts.htmlIt has also been confirmed by the Air Force (which by the way I would assume it is their job to detect underground nuke explosions) that in its own government reports that most of the detection of underground nuclear tests is done by satellites and not by the Coast Guards Earthquakes radar that we are seeing everyday on TV. The Air force says in its report The Counterproliferation Papers Future Warfare Series No. 2 in 1999 that underground nuclaer testing in a hollowed out underground cavern is difficult to detect see

HUMAN OR NATURAL CAUSE: Earthquakes are predominantly natural events. However, shallow-focus seismic tremors can be induced by human actions that change near- surface rock stresses or fluid pressures. These actions include: extracting (or pumping back into the ground for storage or for secondary hydrocarbon recovery) water, gas, petroleum, waste fluids; mining or quarrying activities; and loading the surface with large water bodies (reservoirs). Underground explosions, particularly for nuclear testing, can also generate seismic events (earthquakes).See
