Hydro Tasmania today (Thursday) confirmed there has been no damage identified to hydropower infrastructure following the 4.2 magnitude earthquake this morning in the State’s southwest. 

Executive General Manager of Assets and Infrastructure Jesse Clark said staff were on site within 15 minutes of being notified of the earthquake. 

“We have extensive seismic monitoring. This is a standard part of our dam safety procedures,” Mr Clark said. 

“Our infrastructure is designed to withstand earthquakes of this magnitude. 

“We’ll continue to inspect and monitor over the coming days.” 

Mr Clark assured residents in the Huon Valley that there are no safety concerns relating to Edgar Dam, which is currently undergoing an upgrade. 

The earthquake occurred more than 30 kilometres away from the dam. 

“Edgar Dam as it currently stands can withstand major earthquakes up to 6.8 magnitude along the Lake Edgar fault line,” said Mr Clark. 

“This earthquake was well below that and was not on the fault line. The upgrade will strengthen the dam even further.” 

The earthquake has not impacted the Edgar Dam upgrade works. 

Hydro Tasmania will continue to inspect and monitor infrastructure over the coming days.
