This week began with the aftermath of tropical storm Arthur, whose powerful ocean waves left the Earth’s crust trembling measurably — and audibly — for several days afterwards.

At 01:11 the seismic waves from a large earthquake in Mexico (magnitude 6.9) arrive. Although the earthquake was some 2,500 miles distant, it slowly lifted all of us here in New England up and down by about an eighth of an inch. For several minutes together, we were all dry-land surfers of the deep.

Towards the end of the week, the storm-induced oceanic background noise continues to fade away. As it does, we hear the sounds of two natural earthquakes — one in Japan, one in the Yukon — plus an innocent-sounding little “snap” that belies a more sinister origin: it is an earthquake caused by fracking for natural gas in Oklahoma.

In summary:

01:11
Near the coast of Chiapas, Mexico (magnitude 6.9; 2,538 miles away)
03:49
Puerto Rico (magnitude 3.0; 1,850 miles away)
04:39
Off the east coast of Honshu, Japan (magnitude 6.5; 6,513 miles away)
05:12
Southern Yukon Territory, Canada (magnitude 4.5; 3,051 miles away)
05:23
Oklahoma (magnitude 4.3; 1,664 miles away)
