Tremors deep inside the Earth are usually produced by magma flowing beneath volcanoes, but a new study suggests they can also be produced by the shifting and sliding of tectonic plates.

Scientists have recorded vibrations from underground tremors at a geologic observatory along the San Andreas Fault, an 800 mile scar in the earth that runs through California. The fault marks the boundary between the Pacific Tectonic Plate and the North American Plate.

Tectonic plates are large pieces of the Earth's crust that bump and grind like chunks of sea ice floating atop the ocean. The Earth's surface is made up of about ten major tectonic plates and many more minor ones.

Tremors are sustained vibrations that occur deep inside the Earth.

"Unlike the sharp jolt of an earthquake, tremors within Earth's crust emerge slowly, rumbling for longer periods of time," explained Kaye Shedlock, the program director for Earthscope at the National Science Foundation. ..>

9. I thought it was those little guys who crawl up from the really deep wells

I thought it was those little bald-headed guys who glow in
the dark and crawl up from the really deep wells that we've
recently been drilling.

But it's okay, 'cause Superman will soon be on the spot to
save the day!
