** FILE ** Towering above other structures, the Taipei 101 building is seen in the background in this street scene, Friday, Oct. 17, 2003, in Taipei. The weight of the world's tallest skyscraper _ specially built to withstand Taiwan's frequent earthquakes _ could be causing a rise in the number of tremors beneath it, a professor from the island wrote in a scientific journal. Lin Cheng-horng, an earthquake specialist at the National Taiwan Normal University in the capital, Taipei, wrote that the pressure of the building's 700,000 tons on the ground may be leading to increased seismic activity.
