Quake Watch 2015

I have been away from home for 1.5 days without a computer, so got a bit behind on Chile.
Latest stuff I have just processed;
last 36 hrs map


graph showing the new stuff;
rightclickviewimageforfullsize


map showing all 541 events;


measurement of the main cluster of aftershocks shows a fault length of about 346km (215 mi.), but in the last 36 hrs it has extended a bit south towards the west of Valparaiso. I don't think those are background siesmicity, as there are 9 of them in 2 clusters 10.9 km (6.8 mi.) apart, and 60.1 km (37.3 mi.)south of the main aftershock cluster.


some more maps (while I had the GPS Vis. page open) titles left bottom corner


on the map above the most northern 6 is a 6.3
the rest are tagged below

I haven't really been following the rest of the US lately, just Bald Nountain, Nevada and a sideways glance at Oklahoma.
At first glance it does look quite active over 7 days timeline.
Because USGS have that big gap between 7 days and 30 days its hard to tell if thus is in fact an uptick, I'd have to look at ANSS and see what they have going back over that period.
I guess the Montana and Idaho quakes could be related to Yellowstone in some way, at 330km/200mi scale on the map that Bitteroot Range geographically looks part of the same section of the eastern Rockies as Yellowstone is. Whether that relates siesmically I'm not sure.
Nevada not so much, too far away I think.

the answer may lie here Paleogeography and Geologic Evolution of North America, particularily in the
Late Cretaceous (75Mya)

and Cretaceous-Tertiary (65Mya)

is there a name for your area?
WY ID MT? WYomingIDahoMonTana

further to post by: muzzy
Eric, this map is all the quakes ANSS have for the WYI'___' area for 265 days of 2015.

I have no doubt whatsoever that the activities in each state are related.

edit: what the heck is with the W Y I D M T coming out as WYI'___'
whats with '___' ?

is D M T code for something bad?


and of course a graph of that

Naughty acronym

Seems the code is a bit simplistic.

Oh well.

We know what you meant.

a reply to: pheonix358
isn't that a bit silly
what about dmt lower case?
edit:
seems OK
right, so it's wyidmt or WY-ID-MT then

That link seems to show a steady build of jolts and depth getting deeper all day today....is that odd? Starts at 3.2 and continually builds with each quake.

a reply to: Vasa Croe
Thats the estimating history of the location and magnitude by the automatic seismograph, not the sequence of quake happening itself
see how at the top it shows reviewed, thats it checked by a human

no way it was 3.9, we wouldn't have felt that
Definitely felt more towards where I live, and out east towards Napier


now called
25 km south-west of Rotorua, 167km deep, M5.1

a reply to: muzzy

Ok...thanks!

USGS have 5.0mb
earthquake.usgs.gov...

I filled in the Felt Report form on USGS, they only gave me a Intensity of 3
Geonet gave me a 4 (light)
geez it made me jump though
according to USGS, was 357 away from me

I recognise the style of the details you posted - EMSC
I see they have come to their senses.

675 aftershocks to the 7 day mark

mag6= 16
mag5= 55
mag4= 246
mag3= 338

by comparison the Tohoku-Oki 2011 M9.0 earthquake produced 4271 aftershocks above M2 in 7 days;
mag7= 3
mag6= 48
mag5= 266
mag4= 658

the area I chose for this calculation was 40.9N, 33.14S, 137.27 and 144.9E, a little bit bigger than the official rupture zone, but not by much.


It might be fairer to compare to the 2010 Chile 8.8 though, I'll look into that.

I was monitoring the PNW with GEE and caught these:



This looks to be that 5.6 that just occurred off the coast.

Stay Safe

I am seeing a large dip on the Leavenworth, WA monitor. I saw this earlier today for the same monitor a couple hours prior to the 5.5 nearby.



As a result, I am wondering if we will see another large one kickoff in the PNW in a couple of hours.

Stay Safe!

Sorry lurks - we were writing at the same time

This is ongoing on the monitor in Leavenworth, WA. Whatever it is looks big, but it is not registering on the other two moniros.



ETA: Could this be volcanic? That would maybe explain why this monitor would be registering an event while the island monitor and the distant land monitor would not. It continues to push the amplitude scale.



Stay Safe!
