NEWS: PREPARE THE PADDLES: HUMAN ACTIVITIES CAUSING CITIES TO SINK


Prepare the Paddles: Human Activities Causing Cities to Sink

Human activities are speeding the sinking of major coastal cities around the globe, contributing to more frequent, severe, and protracted floodingLand subsidence can occur naturally, but human activities have accelerated the process in some parts of the globe, leading the land there to descend 10 times faster than sea levels are rising. Tokyo, for example, sank two meters as a result of decades of groundwater extraction. Venice suffered similar subsidence until groundwater extraction was halted there in recent years. Unless action is taken, Jakarta, Ho Chi Minh City, and Bangkok, among other cities, will sink below sea level. More… Discuss

Environment: GROUNDWATER EXTRACTION LINKED TO LORCA QUAKE


Groundwater Extraction Linked to Lorca Quake

Scientists say a deadly earthquake in Spain last year was likely triggered by decades of groundwater extraction, which caused an 820-foot (250-meter) drop in the groundwater level of the Alto Guadalentin basin over the past half a century. The town of Lorca, where the 5.1-magnitude quake claimed the lives of nine people in May 2011, is located in a seismically active region. Researchers believe that the removal of groundwater placed stress on the nearby Alhama de Murcia Fault, leading to the earthquake. More…Discuss
