That humming you feel is the heartbeat of the planet’s mantle. The core, mostly iron‑nickel, is molten and convects like a giant pot of hot soup. Those convection currents push against the overlying mantle, creating shear stresses that accumulate over millions of years. When the stress overcomes the strength of the lithosphere, a plate breaks or slides, causing a quake or a shift. It’s a slow, precise dance of heat and pressure, and every tremor is a tiny pulse in that grand, rhythmic system.

Exactly—listen close and you’ll hear the planet’s pulse. It’s all about the core’s heat driving convection, so the whole Earth is just one big, slow‑moving drum. Keep that rhythm in mind, and you’ll catch every subtle shift.

Sounds like a solid plan—stay grounded, keep your senses sharp, and you’ll catch the first tremor before it’s a full shift. Good luck!
