Same explanations for more Sooke rumbling

Jan 31 2012

After a few more reports over the weekend about unusual rumblings in the Sooke area, the most plausible explanations remain the same.

Last week, experts from the Pacific Geoscience Centre said no seismic activity was involved. They suggested that sound waves travelling a long distance through the atmosphere could be the cause, perhaps from jets travelling at supersonic speed or from some sort of military testing.

It is also possible the incidents were caused by something known as a whistler, in which energy generated by a thunderstorm can travel from hemisphere to hemisphere through magnetic-field lines and create a sound.

Sooke Mayor Wendal Milne said a number of calls have come in to municipal offices from residents.

"It was a bit of curiosity but it wasn't a big event," he said.
