Quake Watch 2015

a reply to: muzzy
Graph for the record, looks like a short lived aftershock series with low magnitudes
see how that 2nd M3.0 popped about 12-13hrs after the main shock, this seems to be a common occurance.
No big deal here but worth keeping in mind for the bigger quakes, to be prepared for it.


deleted graph images, doing some more digging


here is one from 2014 .......... close match

thanks.
That graph doesn't mean to diminish the damage and loss of life a smaller quake can do (sic Christchurch M6.2), or even the accumulation of all the M6's that is still a lot of energy released. 2015 is only half way, so I'm sure the graph will change by the end of the year.
I did 1997 to see what they may look like, its a bit messier

before I go too far with these I wonder if I should put the magnitude in there, as well as/instead of the KT number, or maybe make a "key" to put on each page??

Color code them for magnitude and to make them less busy, lump all of the smaller quakes together and call it 'less than mag 3'

thanks for the reply
They are colour coded already, pink for M7+ and Red for M6.5-6.99, as per my map icons
There are none less than 6.5.
I liked the fan layout as it kind of shows how many events (segments)

The way you answered makes me think I need to put the magnitude of each segment on there, at least the M7's

a reply to: muzzy

Yes, good idea. I am having problems understanding.

People will be people and are interested in big quakes.

What I am getting at is a visual understanding of how piddly the lower level quakes are in terms of the big ones.

IOf there was a single segment for all lesser quakes that said "1251 quakes M6.4 or less, or maybe even M6.9 or less it would show graphically how insignificant they are.

I hope my ramblings help.

For me personally, I like the key idea.

Hakone is not done yet, activity has moved to the west side of Lake Ashi for the first time in this swarm series.

I will keep experimenting, keeping in mind these pies are just for thumbnails on the main page, the key may just be a list of magnitude=KT conversions on the page beside the pie chart.
I hear what pheonix is saying about the colours, will try a few things out,
Thanks for the feedback.

ah ha, another M5 to make an aftershock graph for ,
in 24 hrs

a reply to: muzzy

Hmmmm
maybe not in this case, only 6 aftershocks so far showing on the preliminary data
will have to wait a couple of days to see the reviewed data.
JMA have it at 5.6
www.jma.go.jp...

a reply to: muzzy

only 3 aftershocks on review after 12 hours (latest data)
may be due to the depth, 55.7km
finished up at 5.5


this one started at 5.9 on the preliminary data!

TTNT's are all wrong for 24th and 25th maps, wrong formula, I'll have to fix it later, gotta go to work.

How about this style
1996


1997 (shown previously, I replaced the KT with Magnitude)

The same magnitudes will always vary in segment size between years, as with all pie charts it is divided by % of the total.

Strange 1.6 richter quake happened at northern Finland last week. Explanation from seismic center was "it was caused be explosion of some sort". I heard it myself too, a really loud THUMP. Not an ordinary earthquake.

Now the tremors at Hakone have shifted to the Botanical Gardens, and some still on the Western edge of Lake Ashi
Been a month of activity now.

We are in danger now !!!!!

a reply to: dreamfox1

Is it unusual for the quakes to be so close together time wise? The 6.7 Alaska, the Northern Cali 5+ and the smaller 3.4 central Cali, and the small one in Washington State, all within a few minutes of each other?

Dang it, Didn't feel a thing. I wouldn't have even known about this one if I didnt decide to check ATS just now.

a reply to: dreamfox1

It has to go sometime. The rest of the circle of fire has been letting go. When that segment does go, it will be awful. There is just so much stored energy there now.

Nothing else to say really. I don't like to think of what will happen ... but it will.
