This was my understanding from the article; there's probably a magma chamber shifting in some way, and resonance of pressure waves inside that chamber is causing outward waves to be projected around the earth. The metaphor I imagine is a boat in the middle of a lake having a sudden (non-explosive) hull breach that causes it to fill with water and rock rhythmically side to side. As it rocks, ripples from the boat extend outward in the lake at the same slow frequency that the boat is rocking, eventually spreading out through the entire lake.
- cwkoss 8y agoPardon, I know very little about fluid dynamics. How would a hull breach cause a boat to rock rhythmically side to side?
- apatheticonion 8y agoThe people using buckets to scoop it out, obviously.
- yosito 8y agoI don't know a thing about fluid dynamics. This is just a layman's understanding. But the idea is that as water rushes in from the hull breach, it then sloshes from side to side. It's rhythmic based on the size of the boat and how long the water takes to slosh back and forth.
