The Taiwan High Speed Rail Corp (THSRC) said that although rainfall in 2012 and 2013 restored groundwater in the area below the elevated railway, the land subsidence along the railway has only slowed slightly, the article reported.

Land in Changhua county sank by 6.6 centimeters in 2011, 4.3 cm in 2012 and 3.5 cm in 2013, noted the article, while yearly rainfall has increased during the same period.

According to the article, THSRC spokesman Ted Chia called on the government to work with local farmers and industries to address heavy groundwater use to help end the subsidence.
