>But the ocean is a noisy place, and Kadri said the underwater sounds might have also been caused by underwater earthquakes...
Seismic is rough. Even large earthquake events are localized with large error because of constant noise - seismic event arrivals are hard to pinpoint precisely in time. On top of that, once we have arrival times from a bunch of seismometers(microphones) localization is an inversion problem, dependent on velocity models for a rather heterogeneous earth which further reduces location precision. Even worse, I doubt a crashing jet produces a large magnitude (loud) seismic event, so picking out its arrival in noisy mic data is even harder than it can be for shallow earthquakes.
I'd guess a radius on the order of thousands of miles at best, but it's all contingent on how loud the event was and how noisy the mics that picked it up are.
