Taiwan Researchers Unveiled Cheap Quake Sensing Tool

Technology.am (Apr. 7, 2009) — Taiwan is prone to earthquakes, logging 20 minor ones in the past 2- weeks. Its researcher has unveiled a tiny low-budget device that can sense earthquakes within 30 seconds, enough time to issue crucial disaster warnings, the lead inventor said on Monday.

“We can tell within 30 seconds whether it’s going to be a big or small quake,” Wu told reporters. “We can sense the scale and how much damage it’s likely to cause.”

The tool, which should be fastened to a place unlikely to be shaken by forces other than earthquakes, uses a chip that costs T$10,000 ($302) just a few U.S. dollars, Wu said.
