Australian city on the brink of the abyss

According to a leading geologist, part of Mount Gambier (Mount Gambie) is at risk of collapse in karst failure formed last Thursday, which may one day devour the house or even outside.

When due to heavy rains fell over 100 mm of rain on the city for several hours, residents Ramsay Avenue woke up at night because of the karst collapse, about 30 feet wide, formed near the reserve Acuna.

According to the operational manager of city councilor Darryl Saxton, this is not the first time that the land falls in the area. Mr. Sexton said that only by sheer coincidence dip formed in the empty park, not on someone's yard, but history remembers other cases with unstable soils in the area.

"This one was in the local car park, when the ground has failed and for the first time in this place made a reserve," he said. However, he said, given the geological structure of the earth, on which a Mount Gambier, there is no reason to believe that this can not happen in some other area of the city under the houses.

The famous geologist Bernie Joyce — who has done extensive research in the volcanic history of this area — said that given the composition of the soil of this area, Mount Gambier is prone to the formation of sinkholes.

"The local area was formulated by volcanic activity due to the lava flows, and this means that the underground can be a lot of caves, of which we know nothing," he said.

"Secondly, the local area has a lot of limestone, which can be caused by water to wash, and the soil to be eroded, causing the cave could be produced for a long time."

Mr. Sexton also said that the failures will be filled and planted with grass. "It's a mystery why this is always happening, but I think it happens in the natural natural causes and we will continue to live here," he said.
