Noise record of MH370's crash?

So Australian researchers at Curtin University’s Centre for Marine Science and Technology have combed anomalous noise events from 8 March and found this -

As they say it appears to be typical of earthquakes, but the curmudgeon in me notes that ELF's are something evil that HAARP generates, and so it is probably the fault of the NWO .....

If it was a small earthquake wouldn't they have siesmic recordings of that day, time, and location to help them determine if it was from an earthquake or plane hitting the water.

Both earthquakes and an aircraft hitting the water at high speed would produce low frequency waves. The whole point is that they are analyzing the data to determine which one it was. These signals ARE seismic recordings..

They give a time and location - not sure what your point is??
I would imagine that they could tell the difference between an airplane impacting the water vs an earthquake that starts below the surface.
 
Curtin U's published map defines a long, thin zone stretching from roughly [18.5s, 92e] NW to the coast of Yemen/Oman. This means the sound had to travel between 1,700 and 5,300 miles before reaching the Rottnest detection station.

Speed of sound underwater varies, but if you accept 3,510mph as reasonable, then 1:30am detection time = between 11:59pm (at NW end) and 1:01am (at SE end) event time. Not sure whether the thickness of the region means anything, but it reaches its "fattest" at about 3,150 miles from the sound recorder, which indicates a 12:36am event.

Also relevant: all times above are UTC. Most MH370-related times (e.g. 0:41 take-off, 8:19 postulated time of crash) have been given in Malaysian time = UTC+8h. This means that the event Curtin U has detected took place between 7:59 and 9:01 MYT, or between 7.3 and 8.3 hours into the flight. At the thickest (most likely?) point in the region, the event would have occurred at 8:36 MYT, or 7.9 hours flight time.

If we trust the precision of the 7.5h endurance estimate, the solved-for crash time is 8:11 MYT, which (if the Curtis U event was the crash) gives a solved-for location of around [10N, 60.5E] - the middle of the Arabian Sea.

(The Maldives eyewitness accounts were 6:15 local, or 9:15 MYT, so no corroboration, there.)

All of this requires the Inmarsat data to have been way off - unless something is revealed about THAT, I doubt this new lead will bear fruit.

Didn't china report a seismic event too? That one's been dismissed as not relevant.
Maybe this is being given more credence because it was near the supposed final flight zone.

I question whether the seismic event from a surface impact would travel very far. A seafloor earthquake transmits all of the energy into rock and the water body. A crash would put most of the energy into a surface wave.

A similar argument has been made over tsunami risk in Florida due to the collapse of part of La Palma. A good Florida tsunami debunking site can the found here: http://www.lapalma-tsunami.com/tsunami.html.

Yeah, airplane hitting the sea is not going to be measurable as a seismic event. Especially not a 2.7 ML. The collapse of WTC1 was measured as 2.3 ML. The impact of the plane into the tower was measured as ML 0.9. Flight 93, which crashed into the ground, was described as "less distinct" than the WTC impacts - I can't find a magnitude though.

Water creates a huge drag coefficient. A plane is largely empty air, and the volume of water displaced weighs a lot more than the plane does (which is why planes float). The plane would break up instantly into a large number of irregular pieces.

However, the sea in that location is pretty shallow: 100-200 feet. So there would still be some direct impact with the sea floor. It's just vastly cushioned, compared to flying into bedrock.

On the news last night they commented that these hydrophones are part of the nuclear test ban monitoring system and are very sensitive & their records are only available once the instruments are retrieved from the sea floor - the visual of the trace of the "event" was only bout twice the amplitude of the background. There was a suggestion they might retrieve some from another site to aid triangulation.
