Taiwan database to alert residents to quake danger
Print Edition
TAIWAN has launched a database that will tell residents which areas might be susceptible to creating potentially catastrophic sinkholes in the event of one of the island’s frequent earthquakes.
The research tool shows the potential for soil liquefaction, in which the ground subsides, endangering buildings above. Color-coded maps can be sent in the form of alerts to computers and smartphones when a quake strikes.
Liquefaction is believed to have caused a 17-story apartment building in the southern city of Tainan to topple after a magnitude-6.4 quake struck on February 6, killing 115 people.
The phenomenon was also blamed for many of the building collapses in a 1999 magnitude-7.6 quake that killed 2,300 people and led to a thorough overhaul of building codes.
Most areas at risk are low-lying with sandy soil, or which have silted up over time or been filled in artificially. About three-quarters of Taiwan is covered by mountains ranging as high as almost 4,000 meters, limiting the potential subsidence danger. Taiwan lies on an active fault line known as the Pacific Ring of Fire and is regularly struck by quakes, though most cause little damage.
Separately, the city government in Taipei has allocated US$85,000 for an even more detailed study, local media reported.
The maps show substantial parts of the riverside city’s downtown areas at high risk of liquefaction.
