Quake Watch 2014

Just be alert and stay safe

I wouldn't give it too much notice, although it is in the general area (278km)
the prediction was from Monday, January 7, 2013 - December 2014
almost 2 years span
its 1,344,028 TTNT(M7.3) versus 15,080,242 TTNT(M8.0)
massive difference

lets not hope its not a foreshock,
the 6.0 aftershock was quite a long way from the 7.3 (362.6km)which might mean this is a major fault about to break

plenty of history there (497 quakes above M5.5 since 1990)

goo.gl... (link good till Feb 2015 ........ apparently)

FYI data comes from Wilber3 ds.iris.edu...

Appears to be right in the middle of farmland with no immediate frack pads visible on 2013 imagery.

But then again I did not say this was the event. That may still be to come if their prediction methods work.

a reply to: PuterMan

No, you didn't. I was replying to Doodle's post and obviously replied to the wrong post.

Sorry about that.

Time will tell. Thank you for the math answer, I could not do it in my head. Would you mind defining the terms 'Bigger' and 'stronger' for plebes like me please.

Felt this one down here on the Kapiti Coast!
Vibration, definitely knew it was an earthquake, probably wouldn't have felt it if not sitting down

Eh? another one (may have been happening at the same time, a minute apart) S wave from the East Cape one still going when the P wave from Hamner Springs hit???)
Wow wacked from both sides, no wonder we felt the ground move here in the middle, yeah it did go on for a while

Na h just SiesComp having a fit, this one has changed to a 6.1 East Cape now
could get dropped
was it 2 x M6's or just the equipment having a fit?


geez, now its one quake 6.5

87km east of the 1995 East Cape 6.99
The 1995 (February 5) Waitangi Day sequence, offshore East Cape, began with a magnitude 6.99 mainshock at 22:51:02 UTC at a depth of 12km and was followed by 696 aftershocks events 2.84 - 5.99ML within the first 24 hours of the main rupture.
This one is out the Pacific Plate according to initial Geonet co-ordinates ( reviewed) whereas the 1995 event was under the Australian Plate.
just doing some maps now, 10 aftershocks so far, all quite small

just ran those through GPS Visualiser, they are all in where the 1995 6.99 was, the 6.6 today is out there on its own, could be a faulty location, its early days yet
map after dinner (Stew)


here you go, I put the 3 x 1995 M6 quakes on it too
interactive map of todays 6.63ML East Cape quake and aftershocks to 5:35pm NZDT

here is the latest map based on data from Geonet at 6am, 18 hours, 26 minutes and 45 seconds after the main shock
Not many aftershocks, only 19 in the data for the GL region known as East Cape Ridge Off NI N.Z.
that 3.87 and 4.14 to the north are 175km away from the main bunch of aftershocks and the main shock, so may not be directly related (aftershocks) as this area is pretty active all the time anyway.

Bigger refers to the amplitude of the seismic waves recorded at a seismograph station, in other words the effect on the arm of the seismograph if it was one like the LA drum we look at from time to time. The amount the needle swings back and forth.

Stronger refers to the amount of energy released.

a reply to: dreamfox1

Gee that is a really confusing set of times you have there for an event 2014-11-17 23:09:04 UTC. I guess this is courtesy of Useless who insist in showing quakes in local times when all should be in UTC. A quake in local time is completely meaningless unless you live there just as 15kmSouthe West of Little Puddlwick is meaningless unless you live there.

I guess the US is just peeved that the UK is the centre of the time bands despite the International Meridian Conference in 1884 to determine the prime meridian being held in Washington DC. Just to pay us back they insiston using local times and screwing up the order of dates

Then we have this odd quake here today

6.5Mw at present got GFZ Potsdam

This is pretty much bang on top of the Mag 7+ so I guess you might call it an aftershock although it does not play by the 1 mad difference rules.

6.8Mw for EMSC

Possible Mag 6 - China

www.emsc-csem.org...

Waiting more details

In on Useless as 5.8 mb (which is over 6 Mw)
earthquake.usgs.gov...

Looks as if there a re quite a number of houses within 10 miles of the epicentre. USGS giving it a Pager YELLOW now. Intensity Mercalli VI

Green alert level for shaking-related fatalities. There is a low likelihood of casualties.

Yellow alert level for economic losses. Some damage is possible and the impact should be relatively localized. Estimated economic losses are less than 1% of GDP of China. Past events with this alert level have required a local or regional level response.

6.2 in japan now

Announcement

Google has decided to upgrade the interactive mapping system of Google Maps, from Feb 2015 all my maps will go blank. It has to do with the use of KMZ files which are used to create the maps, it will no longer be supported.
This really pisses me off as I have spent the last 3 years building an archive of interactive earthquake maps, initially for New Zealand, daily/monthly/yearly, but also on EQArchives, a selection of countries on a monthly basis.

The EQArchives pages/maps are a problem, not only is KMZ not going to be supported, there is also a limit on how many events/items/icons one can use on each map
therefore any map with more than 500 events cannot be re created.
So that is the end of USA, Greece, Turkey, NZ, Japan, China etc etc monthly maps as they all have over 500 events on them (the USA has over 5000 earthquakes a month, which I had mapped, but even breaking it down to weekly it still wouldn't work)

Unless they change back to Classic Maps or offer it as an option, or come up with a way to display KMZ files, that is 3 years work down the drain!

I had a look at my Stats and notice some pages that I thought would be popular actually had buggerall readers, such as Turkey, Yellowstone, Mexico, Iceland, L'Aquila etc.
L'Aquila maps really surprised me, only 18 reads, I spent weeks on that to provide a comprehensive series of maps on the whole episode, I thought a lot of people would be interested in that especially afterthe coverage of the Court proceedings agains the geologists in the media. Appears not so.
USA readership is also quite low, only 11 reads of the 2014 year!

Really, I think I have been wasting my time.

I may redo my M7+ pages as I have put a lot of time into that, none of the maps have anywhere near 500 events on them, so they are re-doable, but I might just dump EQArchives altogether.

I have looked into various other mapping systems as alternatives to Googles, but none of them allow importation of KMZ files or if they do allow CSV files importation, its too complcated for me to understand how to use it.

So say goodbye to Mr.Aftershock, it was fun while it lasted.

I will continue to do the New Zealand maps using the new MyPlaces system, and may back track and "upgrade" the old maps back to as far as possible, its going to be a lot of work.
