Australia's most recent volcano



Just something that may interest you..

The most recent volcanic activity in Australia occurred at Tower Hill in western Victoria.  The 'hill', a presumed extinct volcano, last erupted 25 000 years ago, building the ash cone that can be seen today, and sending a river of lava (lava is the name of magma above the surface) several kilometers south to the coast.

The lava forms the low basalt points, rocks and reefs between Kilarney Beach and Port Fairy, the youngest igneous (volcanic) rocks in Australia.  WA has the oldest rocks.  Tower Hill was declared Victoria's first national park in 1892.  It is now a State Game Reserve.
