Surely a plane is too low density to cause even a "small earth quake" when it sinks to the bottom of the sea (probably in many pieces). Could a shockwave from the impact on the surface of the sea be measured as a small earthquake?

- rjsw 13y agoIt doesn't have to impact the sea floor, the Kursk explosion was detected by seismographs.
- masklinn 13y agoThe initial explosion was barely detectable from nearby Finnmark[0] (and undetected from Svalbard or Hedmark) yet was 500kg of concentrated H2O2 and 1000kg of kerosene blowing up.

- masklinn 13y agoUnless it was packed with explosives and blew up when touching bottom Kursk-style[0], that's unlikely. Not to mention the whole area is 80m deep tops, usually much less than that.
