Tremor or Earthquake

Posted Apr 17 2010 12:38am

So last night I was watching some soothing episodes of  “Malcolm in the middle” In between episodes I got up to have a smoke and as I stood up to walk the house moved?!? WTF?!? Did my withdrawals reach a new height of uncomfortable or was that real? I thought maybe a meteor was about to make a spectacular crash somewhere — nearby but instead after 5-10 seconds the house stopped moving and I stood wondering what it was considering I was feeling a little sick from taking my medication to late. Luckily  my Partner was in the next room to confirm it was a real quake a little one at 3.2 – 3.8 (different reports) but enough to bump my LCD monitor and make cups with tea or water in them tremble like Jurassic park. I haven’t heard of any injuries so it wasn’t to bad. Makes ya wonder if there will be more.

This was the first time I had experienced any kind of tremor. What a night. I went outside I could hear a lot of people on the streets talking about it, excited, scared in awe. I went back to watching ‘Malcolm’ and enjoyed the rest of the night feeling like I don’t worry over nothing.

Here’s one of the reports I found shortly afterward.

Adelaide hit by earth tremor

The quake struck Mount Barker, in the Adelaide Hills, about 11:27pm ACDT (Google Maps)

Residents of Adelaide in South Australia were woken last night by a 3.8-magnitude earthquake.

The earthquake happened at 11:27pm and people living within a 50 kilometre radius of the quake reported tremors lasting for up to 15 seconds.

The epicentre was close to Mount Barker, 40 kilometres east of the capital, in the Adelaide Hills.

Mount Barker resident Robert says he heard a loud bang when the quake struck.

“We heard a terrific explosion,” he said.

“We live right opposite the golf course and lots of galahs roost in the trees and they made nearly as much noise as the earthquake itself but it was definitely an explosion.”

Paul in Bridgewater emailed ABC News Online, saying: “Whoa! We just had what seemed like an earthquake go through our house.”

Meanwhile, Steven from Moana said: “Several of my neighbours came out into the street and said that their houses shook like mine did. It lasted for about 10 to 15 seconds.”

There have been no reports of injuries or damage to buildings in the capital.

David Jepson, a seismologist from Geoscience Australia, says while tremors in the region are not unexpected, this quake was larger than normal.

“This would have been felt quite widely, up to about 50 kilometres from the epicentre, and we’ve had a number of felt reports from the region,” he said.

“That’s basically shown that it has been felt quite widely across Adelaide city.”

David Love, a seismologist with the South Australian Department of Primary Industry and Resources, says further activity along the fault line cannot be ruled out.

“This is probably the largest earthquake near the Adelaide area for quite a long time, possibly in excess of 20 years,” he said.

“An earthquake that size will give a fair shake near the epicentre, its certainly enough to wake people up, but most unlikey to cause much other than that.

“There is a chance of more activity, I think the chance is fairly low, but we can’t rule it out.”

Mr Love says data is still being collected but the event appears to have occurred more than 15 kilometres below ground.

“From the reports that have been coming in it looks like it may have been a relatively deep earthquake therefore lessening the effects immediately above it on the surface,” he said.

The quake was felt around Adelaide and more than 100 kilometres north of the city as well as on Kangaroo Island.

I really thought it was cool. I get excited over anything new, I think we always think we wont have natural disasters here and this is a reminder that this planet is still very geologically active. Maybe it was a bump to remind us to take care of it.
