Quake Watch 2016

a reply to: muzzy

Muzzy, hold on to something. Every time I see an update it's New Zealand. The first was Christchurch and now there's three on the North Island in a line. I hope this is one of those multiple small movements that alleviate stress.

It has been pretty quiet for a while here, apart from that 1tth Apr Mt. Holdsworth
Even the Kermadec's aren't putting out much

a reply to: muzzy
Aftershocks are headed back east towards Carterton, which is good I guess.
Confirms what I was saying about the Graben being the cause, rather than uplift of the Tararua Mts.

Busy place.



Sorry, first attempt at this. I love reading this thread though. Maybe I should just lurk.

have updated that.
Brought in the Amasuka Region, which I had missed before, just had W of Amasuka.
Its getting a bit cramped near the end of the graph, but you need to look at the whole time period to be able to get the point. I could make it wider, but I need to leave room for more events before I expand it further.
W off Amakusa Is/Amakusa Region over the SW of Kyushu events and the Kumamotos series timeline graph
and the
page where it came from. Hopefully it doesn't take forever to load for you, there are a lot of maps on there.



Now back to my own back yard and get 11.05.2016UTC map done. Will update the Mt Holdsworth series as well.
Not as many events as I thought there would be only 65 for the whole country for the 24hr period, about average.

a reply to: muzzy

Very nice as always great work and it loaded quick for me.

Just not sure if it suppose to show land mass as i see all blue with the dots.

nevermind fixed it was on my end ofcourse. lol

a reply to: Onesmartdog
yeah a few moderate sized quakes in the last 24 hrs, more than normal background activity that's for sure.
Lucky for clarity they all fell within the UTC definition of a "day"

Not a heck of a lot of energy released though, even with two high fours and two low fives, only 1942.998 TTNT


Oh just to clarify, before I update the Mt Holdsworth page, todays moderate events were 4.66 and 5.16, Geonet round the numbers off to one decimal point on the public pages,
so these less than the original 11th Apr 5.2, there fore aftershocks (ie this is not a "swarm" as such,
but close

Mt Holdsworth page updated
not too happy with the graph, like the Kyushu/Awasuka/Kumamoto graph because its so long a time period ( 1 month in this case) the new stuff is very compressed at the end of the graph
I have an idea to do two graphs and another map showing the split timewise, but I'll need to make some new icons and load them to Dropbox first. Luckily the weather is crappy here right now, strong winds, rain coming and I have some spare time.

That didn't take too long
I wanted to see for sure the spread of the two M5's aftershocks. Yup moving SW. The Bing map version is the best in this case. The map below shows the two aftershock sequences split by colour, blue are the original 5.2 aftershocks and the red are the 5.16 aftershocks, green is the single foreshock. The size of the icon shows the magnitude.

After the large quake Taiwan had in Feb 2016, they just had another one - 5.6, originally assessed as a 5.9 by the USGS.

Sounds like some power outages and people trapped in elevators but no reports of major damage or loss of life.

a reply to: StoutBroux
yep,
5.8ML
then
5.5ML
couple of 4.4's and a 4.0 and high threes too Central Weather Bureau Taiwan

Muzzy, I've been keeping a rough daily total for Mexico. So, I wouldn't be asking if I thought it was about it's "normal" amounts. However, and I'm not trying to to forget or ignore that 6M recently, it again seems like Mexico is above, even it's recent high number of earthquakes. The daily lists contains 100. I'm having to change settings just to look at one day and make sure I'm getting all the updated earthquakes.

Oh, and Nevada/Empire swarm is still popping off with ones around 2.5M

JMA reckon they were 6.5ML and 6.4ML;
JST, UTC, Lat, Long, Mag, Type, TTNT, Depth, Location
12/05/2016 13:29:57JST, (04:29:57UTC), 24.698, 121.998, 6.4, ML, 60035.5, 31, TAIWAN REGION
12/05/2016 12:17:15JST, ( 03:17:15UTC), 24.659, 121.924, 6.5, ML, 84802.4, 36.7, TAIWAN REGION
Their Aqua Division hasn't converted to Mw, I guess they have enough on their plate with earthquakes in their own country.

a reply to: ericblair4891
Are you asking for a Mexican timeline versus magnitude graph? over a month? or longer?
Don't forget it's magnitude not numbers that counts.
Ill see what I can do after I get Japans daily troubles out of the way
FWIW SNN had 72 events for 12/05/2016

a reply to: muzzy

I know you like magnitude. I was thinking it's both really. There's more and they've been getting a bit bigger. Today, some of the latest have been around 4 and above, whereas, previously they've all been give or take 3.5 Mish.

Just look. If the numbers aren't interesting, don't worry too much.

But the average recently has been 50 plus a day.

a reply to: ericblair4891
No problem, it has been 50 days since you asked about Mexico (when I did the last graph) i can handle that.
I had the pre 24th March data already.
yes the numbers are on the up and up, especially the last week
Mex. timeline to May 13
each number at the bottom is the day number from Jan 1.
the yellow totem pope is when I did the last graph.

Muzzy, Thank for the reply. Learning as I track this thread. Thank you !

Note about change on graph in post by: muzzy
I added some value to the numbers graph by making the days with M6 quake full Red and days with 5's Orange.
Shows that having a M6 or M5 doesn't always correlate to big numbers of quakes in 24hrs, although it did twice.
Like just about everything to do with earthquakes, its pretty random

Golly gee, I had hoped someone else would have pointed out that Nevada had a 4 M at Empire. Hmmm.

earthquake.usgs.gov...

Heck, if there's a big one, we'd have to maybe say these were foreshocks. I'll reserve judgement. Only 'cause I am older and not as ready to see the whole long term trend. 4M wouldn't really be considered a mainshock. So, the only thing to say for the moment is... " oh my, hmmm"

Mexico is not just my imagination. There's a defined increasing trend. Forget about the mystery of the year over year reporting. Just the recent stuff is show growing output of energy. Central America went offline. Not gonna say anything.

Because, the only real motivating factor for me to write, was that I have notice a sudden drop off in the Northern Nevada earthquakes. Because, well, "oh, my, hmmm", it seems very coincidental to the sudden increase in a swarm just to the south in Empire. How can I not connect this change. The one thing about the Northern Nevada earthquakes was that they were the "Energizer Bunny and kept going..." I mean, hey yeah, there's been times it almost seemed to have stopped only to come back. So, maybe that's it. Just the normal swarming of Nevada. Either spreading crust, or old mountains groaning, whatever they may be, Nevada is interesting.

I'll be wrong as soon as I write this, maybe. But, I think that we're kinda at a low ebb right now. Not much bigish. Again, it seems earthquakes come in clusters.

a reply to: ericblair4891

Same thing happened at Kyushu Japan, as the SW of Kyushu series died off the Kumamoto started. Then as Kumamoto died off SW started again. Those are Tectonic, maybe the Salton/Nevada are too.

Thought some of you might be interested in watching this.

Ottawa, Canada just had a 3.0.

The seismograph is really catching some activity.
