The 11/11 rumble heard around the world

Various scientific journals are reporting on a strange planetary event that occurred on November 11: During the morning, just before 9:30 UT, a mysterious rumble rolled around the world.

According to NATIONAL GEOGRAPHIC:

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 ChileNew ZealandCanada, and even Hawaii nearly 11,000 miles away.

And more from the magazine:





“I don’t think I’ve seen anything like it,” says Göran Ekström, a seismologist at Columbia University who specializes in unusual earthquakes.

The French Geological Survey (BRGM) is closely monitoring the recent shaking, and it suggests that a new center of volcanic activity may be developing off the coast. Mayotte was formed from volcanism, but its geologic beasts haven’t erupted in over 4,000 years. Instead, BRGM’s analysis suggests that this new activity may point to magmatic movement offshore—miles from the coast under thousands of feet of water. Though this is good news for the island inhabitants, it’s irksome for geologists, since it’s an area that hasn’t been studied in detail.
But remember, this was NOT an earthquake.. scientists are stumped as to what the waves were.
