Couldn't edit the above post, so....just noticed another seismo has just registered 'movement' in central Victoria....will add info here if I can get some more information from it.

Here's a link to one of the seismo's I observe. It is currently quite active. I meant to add it in a previous post.

Leon Mow Dark Sky Radio Observatory (central Victoria)

Check out the Leon Mow Dark Sky Observatory (link in above post).
The seismo has been going off for some time now.
Now...my amateur seismo is subtly corresponding with the movements in this seismometer.
Trying to work out why Leon's seismo is going 'beserk'.
Geoscience hasn't noted anything yet.....

Hi all, just new here, did an earth sciences degree many years ago, but been out of that picture for a long time. Noticed this and the volcano topic today and it's re ignited my interest, pardon the pun. Always been interested anyway, rather rusty tho! Born in NZ and experienced a few earthquakes, been up Mt Ruapehu during student days. In Aus since 1990. Will keep an eye on this topic.

Hi BlueMoon.
Can I be the first here to welcome you to WZ and this thread.
I may seem to hog the thread here just a little bit, but it is an interest of mine. I am a complete amateur regarding seismology, so your experience in this area will be appreciated by me and many others here, I am sure.
I also need to pick my cousins brains a bit more too (he is a seismologist), but unfortunately I don't see him much, as he trots around the globe a fair bit, Switzerland etc..
Anyways, cheers to you and I'd like to know what you think of the activity on Leon's seismograph I've been gabbling on about smile I've got a bit of a feeling about it, but I'll 'sit' on my thoughts for now.
Best wishes, Duck.

Hi duckweather, thanks for the welcome. Actually Icve been ready wz posts for a while, especially east coast weather events, and posted on a topic there this morning, my first ever forum post lol. Anyway, like I said, I'm VERY rusty, you've got it all over me, I'll be learning from you! I was so pleased to see (your) topics that I jumped in straight away. Haven't read much yet, that's all I'm good for for now lol. But I certainy know what you're on about and wanted to express my interest.

Wow....that is very kind of you BlueMoon. Shucks, another blush
As I said, I am an amateur here. I tend to go on instinct mixed with the odd observation and no formal training in this area.
Hope you enjoy your time on WZ. We are a great bunch, if I may say so myself.

Welcomega to Weathzone Blue Moon!

Was reading on ABC that a local Tasmanian seismologist put the Tassie quake down to the Australasian plates northwards movement and a build up of stress associated with that movement.

But I wonder if there's any association with the Australian Hotspot which is somewhere in that area (in the strait I believe).

Hi Xavo, thanks for the welcome. I can see I have to swat up on Aus geology haha. Ummm, it's possible there's a link between the hotspot and the earthquakes, but normally they're more plate movement related.

Blue, I'm just wondering what field you studied in your degree?
I'm just about to start second year Geology with a dual degree of Geography.
Have you got any good books to recommend?

Xavo I did Earth Sciences in NZ 30 years ago...makes me an old timer now haha. It was a broader degree than geology and my interest was in palaeontology and plate tectonics. Worked for a while with coal core sampling then had kids smile Where are you studying, and is it seismology? Can't help with books sorry, you're more up to date than me!

Hey Xavo....I found an article from The Age from 2009 regarding the HotSpot you were talking about.
Bass Strait hotspot

I am sure there is a later dated article about this region, but I'll have to go through my clogged files to find it. I'll post it for you if/when I can 'dig' it up.

Cheers, Duck.

Ah right, I'm studying at UQ in Brisbane but to date have only done one proper Geology course. It really ramps up in second year though. I like all aspects, but probably Volcanology and seismology interest me the most. Not too keen on the geophysics side of things poke.

@Duck, I'll have a read of that article now. Thanks for the link.

Haha, got to take bad with the good. Yeah, 1st yr is a bit slow, 2nd year is the best, 3rd year all business. Is it a 3 yr degree or 4? Geomorphology was my 'unpleasant' subject. Are you doing any holiday field work or just waiting for the rain like the rest of us?
Just read the bass strait volcano article posted by duckweather. Am about to google more over a coffee!

No field work yet, but hopefully I can get some contacts and get s8me work this year.
I know there's one subject that mainly focused around field work that's coming up.

Ok my fellow EQ interested Wz's. As some of you know, I enjoy coming up with some obscure info from my cluttered collected files.
Well, I dug up a fascinating newspaper article (from a site I can get a little obsessed with on occasions grin ) from the Argus Newspaper of Melbourne, dated 4th July 1885.
The article is about The Earthquake which rattled Melbourne at that time.
Hope you enjoy searching for other EQ (and other articles) in the archives of this site wink

Leon Mow's seismograph is operating in real time again. This particular seismo is situated at the TOOLANGI Station, 55 kilometers north east of Melbourne.

If you look at the page, it is the seismo 2nd down the page.
Toolangi seismograph

The seismograph above it is 'stuck' at the moment, and is not reading 'current time'.

Now, before you read what I'm gonna say below, many people today and back to ancient times believe in the following;
If you look at the Melbourne sky currently (and for the last hour or so) you will see it is riddled with (laymans terms) ribbed clouds. To some this is a sign of (or precursor to) an earthquake/tremor.
Now....I keep an open mind regarding the presence of these cloud formations...and an 'on the fence' as to whether they are just a natural phenomenon due atmospheric/wind conditions or maybe signs of "geomagnetic" disturbances.
Within one section of these clouds I thought I saw a horizontal 'rainbow' as well.
So Daffy Duck (me) is prepared to be 'advised' by the knowledgeable WZ's here as to their opinion on these cloud formations. I'd like to know what y'all think wink

I assume you mean Cirrocumulus clouds: If there are only small patches of cirrocumulus and perhaps some wisps of cirrus, it usually means a continuation of good weather and if it is seen after rain it usually means improving weather.
No I do not believe it has anything to do with that. As you posted this around he time the sun is lowering in Melbourne I assume the sun inter racted with the ice crystals at the right angle creating those 'special effects'. High clouds do this very often.
http://en.wikipedia.org/wiki/Circumhorizontal_arc you can also read this as for your sighting of a fire rainbow type of thing.

Thanks Ant.
I took photos of all the formations I saw yesterday. Apart from being like a kid with a new toy with practicing with my new camera ( grin ), I was interested in (and curious about) the huge spread and shape/structure of these spectacular clouds, so I took some pics. Just need to upload them to the computer now.

Cheers, Duck.
