What rang our bell?

Nobody seems to know, yet the planet rang like a bell recently.

On the morning of November 11, just before 9:30 UT, a mysterious rumble rolled around the world.

The seismic waves began roughly 15 miles off the shores of Mayotte, a French island sandwiched between Africa and the northern tip of Madagascar. The waves buzzed across Africa, ringing sensors in Zambia, Kenya, and Ethiopia. They traversed vast oceans, humming across Chile, New Zealand, Canada, and even Hawaii nearly 11,000 miles away.

Over the eons this has probably happened many times before. Today we have instruments that pick up the rumblings; in years past we didn't.

As I have aged, I have had strange rumblings in my gut. And the earth is even older than me. Just a bit of intestinal noise from Momma Earth.

OK

Here's the liberal view

Sorry.
