According to my brief research, there are more than 2000 earthquakes per year on average around magnitude 5.0 or above.

Many thanks....

[TEITS]

Whilst I enjoy reading this thread I do have to wonder if its worth posting about earthquakes with a magnitude of 5.0. The simple reason being is they appear so frequent.

this is very true, if everyone referred to this link:-

http://earthquake.usgs.gov/earthquakes/recenteqsww/Quakes/quakes_all.php

it would save yamkin a lot of posting time...

[stormforce 10]

yep i agree. its a bit silly posting every time and earthquake happens.

would be better of doing a round up in the evening of all the earthquakes.

only post when an earthquake over mag 6.0 happens.

oh, but then I'd miss the alignment date changes...They change every day you know?......

On topic, for this thread what is the criteria for a significant earthquake?....I mean if there are over 2000 earthquakes of magnitude 5 or above every year on average, I'd suggest a change to perhaps magnitude 6.0 or above...From memory, when this thread was started years ago, only newsworthy quakes were posted on (and when I mean newsworthy, I mean quakes that actually were reported in the general media)

Edited September 7, 2011 by ajpoolshark

[Osbourne One-Nil]

Yes - I agree.

Only magnitude 6.0 (STRONG) EARTHQUAKES TO BE REPORTED IN THIS THREAD FOR THE TIME BEING.

Any which are reported below this will be removed, unless it is considered there is good reason for their inclusion.

When it is considered that Earth is safe from impending doom, we may reconsider this.

in the link i posted, they highlight anything above mag 6.0

Thanks for the link BD.....a wealth of info on the USGS site, including summaries and detailed analysis on individual earthquakes....For anyone with an interest in this field, and who hasn't yet frequented the site, then well worth a visit

I agree. The site is very good and I have learnt quite a lot info. I'll devote more time to my YouTube site. Be safe and peace.

[john pike]

can i ask the people that read this but never post

what would you class as a quake that is important.

ie if you get a 6 earthquake with a huge depth this is

unlikely to be unimportant.

however if you get a 5 quake and very shallow in certain parts

of the world this can cause immense damage.

Also does a swarm at katla not come over as earthquake news

or the uk for example.

also the usgs site does not show all earthquakes.

http://www.emsc-csem.org/Earthquake/seismologist.php

look at this

now click below

http://earthquake.usgs.gov/earthquakes/recenteqsww/Quakes/quakes_all.html

there is activity in iceland again but because of this i will not report.

i think quite a lot of people read this thread and only a very few have criticised it.

anyway i will now go back to following the weather and i hope my input was interesting

for the people who read the thread

John,

It's not other people's fault this thread has gone off track and this perhaps arbitrary guideline has been set. It's purely a response to the over-zealous and unnecessary reporting of every single earthquake to, we can only assume, prove an ever-shifting and outlandish theory.

[summer]

Hi,

I've never posted before been an observer for a couple of years and a member since January. I completely agree with John, I think we would miss so much if eathquakes below 6 were not reported especially regarding Iceland but also the quake swarms at El Hierro, Canary Islands. Both of these could impact the UK and are incredibly fascinating! But I do think some are sensationalising, I'm not sure what the right way to correct this would be but I don't think reporting just over mag 6.0 is right. Just my twopeneth!

knowm on the forum as Summer although member name is Willow Woman also Rebecca from North Yorkshire! bit mixed up on names!

[Crepuscular Ray]

Although they're earthquakes, perhaps swarms under Katla, etc. (as opposed to every minor movement) might be better posted in the volcanic activity thread.

Edit:

Al-Jazeera are reporting a mag. 6.6 in the vicinity of Delhi, although there's nothing on either the USGS or EMSC websites yet.

Very good point John....I've had a passing interest in tectonics & earthquakes but profess to know little about it...Having researched the USGS site today, it has become quickly apparent that the earthquake magnitude is just one of several parameters that the USGS look at when judging how signigicant an earthquake is...
