An earthquake measuring 4.

7 on the Richter Scale has caused minor damage in Western Australia's Southern Wheatbelt.

The quake struck just south of Katanning and was felt as far away as Perth.

Broome Hill resident, Grant Taylor, says he heard a deafening boom just before eight o'clock this morning leaving his house with minor damage .

"Mainly down one end of the house, there's some big cracks in the brickwork".

GeoScience Australia's duty seismologist, Spiro Spiliopoulos, says it is the largest quake to hit the Great Southern in decades.

"It's the biggest earthquake in about 40 years so it's unusual in that regard".

Doctor Spiliopolous says tremors were even felt in some high-rise buildings in Perth, more than 270 kilometres away.
