Officials seek cause of renewed Assumption tremors

July 7, 2012 

BATON ROUGE, La. (AP) - Officials are seeking seismic equipment to try to understand tremors in a swampy area of northern Assumption Parish.

The Advocate ( ) reports that tremors were reported again Tuesday and Wednesday mornings. They had first been felt last month.

Natural gas has also been roiling Bayou Corne and Grand Bayou, but officials are not sure if there's a connection between the natural gas and earth movements. The area is between Pierre Part and Napoleonville.

Officials have been focusing on oil and gas infrastructure in the area to find the source of the leaking gas. Salt domes used to produce brine and store natural gas are also being examined to make sure they are intact. A cavern owned by Chevron Corp. has been tested and state officials are expected to release results next week. Another cavern owned by Acadian Gas Pipeline of Houston has been closed for five days and is being monitored, said John Boudreau, director of the parish's office of Homeland Security and Emergency Preparedness.

Parish officials said natural gas levels detected on an air monitor in the Bayou Corne area rose Thursday to 25 percent of the levels that could produce an explosion, but said the reading is suspicious.

Parish Sheriff Mike Waguespack warned people Friday not to tamper with monitors. He said anyone caught tampering or trying to feed the monitors some type of foreign source "will be handled accordingly and will be arrested."
