Did the Earth Move for You or Was That Really an Earthquake ? a Tremor at Least !
New Tremor Felt
Update 19 - 07 - 2012
Well Victoria is getting a reputation of the 'shaky state'. Maybe we should call it "The State that Moves"?
Another tremor reported at a 5.2 strength (now updated to a 5.5 strength) hit Victoria about 8.55 pm (Australian Eastern Standard Time) and some say it lasted for about 30-40 seconds.
At this point of time the epicentre is said to be around the Moe area which is in the South Eastern part of the state. No reports of serious damage as yet!
Update on Tremor 05-07-2011
Well folks it happened again, around 11.30 am today (15 minutes ago) the Earth moved again!
Another major (for us anyway) Tremor struck Victoria and made our house shake quite a bit.
At first I thought it was the wind (it had been blowing at up around 90 or so Kph) but at that time there was a lull.
First the windows started to rattle and the thought went through my head "This is odd the trees are not swaying with the wind". Then the chair I was sitting on started to rock sideways and I thought again " This is not the wind we are having another Tremor, I hope that is does not get any worse". Visions quickly flashed through my mind of the recent Natural Disasters in Japan and New Zealand.
The Tremor lasted for about 15 seconds or so but it sure seemed longer than that at the time!
Reports have put the Epicentre in the same location, Korumburra in Gippsland, as the last tremor I felt with a 4.4 intensity. I will update this as more news comes forward.
Did the Earth Move or What
I just have get this off my chest and tell you that last night, for me the Earth moved .
If you are thinking that this may be a hot, sexual tale you can stop reading right here!.
The Earth literally did move, we had an Earthquake of the ground shaking variety.
Just before 9pm I was talking to my good mate Ern, who writes Hubs as “Ernestshub”.
Ern is also the chap who introduced me to HubPages.
We were chatting away on Skype(as you do) about Erns new venture at “Ern's Choice Software” a website were he will be supplying a range of software and is a new venture for him, when WHAM!!!!.
“F**k what was that?” I said.
By the time I had that brilliantly elucidated piece of Strine out of my mouth Ern had also felt the Quake.
The first thoughts that came to my mind were that perhaps a truck had smashed into our place or a tree had fallen due the drought and hit the house. My first reaction was to make sure that the family had suffered no injuries and property not been damaged. Everything OK on that front.
For the Technically minded of you , the Quake measured 4.7 on the Richter Scale and its Epicenter was just near a beautiful little Country Town called Korumburra about 70km (45miles approximately from my place. From what I have been able to learn up to this stage, anything higher on the scale can start causing serious structural damage , injury or loss of life.
Dean Collard says he was working at a service station in Korumburra when the earthquake struck.
"All the shop walls were going back and forth - we had a lot of stuff fall off the shelves, all of the auto section went," he said.
"We had a couple of customers in the store at the time - a lady's just started feeling the earthquake, bolted for the door screaming 'we're all going to die!'
"It was pretty comical, but at the time fairly serious."
ABC Online reader Heather Redmond, who lives at Seaview approximately 20 kilometres north of Korumburra, says last night's earthquake follows a less severe tremor felt in the region about a month ago.
"There was quite a load roar and the house shook that much that the heavy arm chairs we were sitting in moved," she said.
"The walls were moving also - it lasted about 30 seconds.
"There were several after shocks and I felt a smaller tremor at 3:00am [AEDT] today."
ABC Online reader Karen Layland, from Lock Village about 10 kilometres from Korumburra, also felt a second tremor.
"We had a tremor about 8.54pm and it lasted for a few seconds sending plates smashing as the dish rack fell on the floor," she said.
"It was very scary, sending my dog in a panic - I didn't know what had happened.
"We had a smaller one between 2.00am and 3.00am which shook the whole house waking me up, scared again."
Last night's earthquake was Victoria's strongest since 2001, when a 4.8 magnitude tremor was felt in Swan Hill, near the Victorian-New South Wales border.
It is very unusual for Australia to experience earthquakes , although we did have a very serious quake in Newcastle in 1989 at a magnitude of 5.6 on the Richter Scale.
At the time it was one of Australia's most serious natural disasters, killing 13 people and injuring more than 160 others, and the damage bill has been estimated at A$4 billion ,including an insured loss of about A$1 billion. A lot of money in 1989.
The earthquake caused damage to over 35,000 homes, 147 schools, and 3,000 commercial and other buildings, with significant damage caused to 10,000 homes (damage worth over A$1000) and 42 schools (structural damage), within the immediate Newcastle area.
The Newcastle earthquake was the first Australian earthquake in recorded history to claim human lives.
Coincidence or What?
I don't know if it was a coincidence or not but “Geoscience Australia” seismologist Phil Cummins says the quake was one of three similar tremors that struck yesterday.
"There was one that occurred up near Broome on the North West coast of Western Australia and one that occurred near the town of Beacon which is located about 340 odd km North East of Perth in the Western Australian wheatbelt," he said.
"Those were both close to magnitude five ... They occurred in remote areas so they were felt by far fewer people than this one.
"It is quite remarkable that we get three of roughly this size in one day. An earthquake of this size typically happens maybe twice a year in Australia."
Up to this point of time there have been no reports of major damage.
It will be very interesting to see how many insurance claims will eventuate out of this and how many will be classed as pre-existing damage?
Most earthquake insurance policies feature a high deductible, or excess as its known in Australia, which makes this type of insurance useful if the entire home is destroyed, but not useful if the home is merely damaged. Rates depend on location and the probability of an earthquake.
Earthquakes in Mythology
In Greek mythology, Poseidon was the god of and cause earthquakes. When he was in a bad mood, he would strike the ground with a trident, causing this and other calamities. He also used earthquakes to punish and inflict fear upon people as revenge. Just the sort of guy you need to rule your country.
The stature shown here is how he may have appeared to we mere mortals.
Now there is a guy you would not want to “piss off”!
In Norse mythology
In Norse mythology, earthquakes were explained as the violent struggling of the god Loki. When Loki, god of mischief and strife, murdered Baldr, god of beauty and light, he was punished by being bound in a cave with a poisonous serpent placed above his head dripping venom.
Loki's wife Sigyn stood by him with a bowl to catch the poison, but whenever she had to empty the bowl the poison would drip on Loki's face, forcing him to jerk his head away and thrash against his bonds, causing the earth to tremble. They should bring that punishment back for murder, what do you think?
What is an earthquake?
Very simply put an earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!

We just had another Earthquake
Just to let you know about 4.30 this afternoon we had another Earthquake.
It felt about as strong as the last one but it seemed to last a bit longer than the earlier one. There is no reports of damage.
According to an "expert" on the radio it is unusual to get two earthquakes with the same epicenter so close together?
