"In a way, seismic waves are like medical X rays. They allow the seismologist to get an indirect look under the planet's skin. Just as medical X rays pass through bone differently than they pass through soft tissue, seismic waves pass through the solid matter within the planet in a manner that is measurably different than th"
"We can use arrival times and amplitudes of phases to determine the interior structure of the Earth. In fact, most of what we know about the interior of the Earth comes from this kind of information. Seismic waves are like the X rays of the Earth. We can CAT-scan the Earth."
"When an earthquake occurs, it releases waves of energy, which are known as Seismic waves. It is like the ripples created in water if you throw a stone in it. Seismic waves are like those ripples which can travel through the inside of the earth, as well as on the surface."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
