Build your own Quake

CNN.com - Has tallest tower caused more quakes? TAIPEI, Taiwan (Reuters) -- Seismic activity in Taipei has increased since the world's tallest building, Taipei 101, was built, raising questions over whether the Taiwan capital has become more vulnerable to earthquakes, a geologist said on Friday.

Lin Cheng-horng, a geologist at the Institute of Earth Sciences at Taiwan's most prestigious think tank, the Academia Sinica, said seismic activity historically had been low in the Taipei basin, home to about 7 million people.

But the city has experienced more micro-earthquakes (of magnitude 2.0-2.5 on the Richter scale) since construction began on the 508 meter (1,667 foot) skyscraper in 1997, he said.
