quake, shake, tremble, quiver, shiver

Mnemonic

Dark rain hammers the mountains, awakening a slumbering dragon deep underground. The dragon stretches its massive body, and the entire landscape begins to quake — the rain intensifying with every tremor as the beast rises.
Additional thoughts
Picture the rain drumming on the cavern ceiling, irritating the dragon awake. Rain sits on top of the kanji, dragon on the bottom — rain above, dragon below, shaking everything between them.
Quick recall
Rain wakes a buried dragon, making the world quake.
