EARTHQUAKES in South Australia's mid-north have prompted the State
Government to issue an earthquake safety warning.
The first quake occurred just before 9.30pm on Friday night, was
centred north west of Clare and had a magnitude of 3.2 on the Richter
scale.
The second quake, which happened about 1pm on Sunday, had a magnitude
of 4.1, an epicentre east of Peterborough, and was the most powerful
quake in Australia since one of magnitude 4.2 north of Quorn on July
30, Adelaide Now reports.
When and where earthquakes will occur is unpredictable, but the
government safety message issued at 3.30pm says people should be aware
of the basic steps they can take in the event of a major earthquake.
Most earthquake-related injuries result from collapsing walls, flying
glass and falling objects, or when people try to move more than a few
feet during an earthquake.
In the event of a major earthquake, people indoors should stay there
and seek shelter under a door frame, solid table or bench and not use
elevators of lifts.
If outside, people should keep clear of buildings and other structures
such as powerlines and trees. Motorists should move away from hazards,
stop the vehicle and listen to the radio for advice.
Damaged electricity, gas and water should be turned off and phones used
only in an emergency.
People should have a designated meeting place with loved ones if they
get separated and keep an emergency kit, including a battery powered
radio, torch and spare batteries, on hand.
Quakes of magnitudes less than 3.4 are usually only felt by a few
people close to the epicentre.
Those with magnitudes 3.5 to 4.2 are felt by people indoors and some
outdoors and usually feel like the vibrations made by a passing heavy
truck.
