Quake Watch 2015

Just saw it myself. A few little ones there too.

Notice that one before the bigger one? Interesting

Love that link!


It was upgraded to a 4.8 now on USGS.

M4.8 - 184km W of Port Hardy, Canada

I like it too.

However, it seems sometimes stations go out too conspiculy. (sp. Sorry I'm so tired I should go to sleep).

If you watch long enough, you'll see what I mean. I even e-mailed them and asked them the question. There reply was (The pink lines mean the station is out of order). They had nothing else to say.

I sometimes watch these stations and when there is any movement, that's when it seems to go out. I dunno, crappy equiptment?

This is Bella Bella.

Sorry, It won't let me pick up other station to link.

But anyway, check out some of the other stations in the area. It's kinda cool to compare them. (or for me, try too.)

a reply to: crappiekat

I just wanted to add.

I look at the west coast of Canada as extremely interesting. It seems very quiet there considering what is happening North and South of it.

I just think there is more going on there than what is being monitored. The permafrost is melting. And to me, it has to have alot of effect on the plates.

TA has an interesting thread around here somewhere about the area.

Honestly, I am just too tired to look for the link.

But I am going to keep watching. Check out what going on else where.

a reply to: crappiekat

Check this out. About the same mm.

This one has to be closer to a 5. Nothing from USGS.

a reply to: crappiekat

Watch the TMD. We might be getting another one.

Hello friends.

So what do you make of the small magnitude activity SW of La Pine, Oregon today? Activity began at 09:22 UTC on the 22nd, with a tiny Mag 1.1. As of right now, 04:20 UTC on the 23rd of October, there have been 25 earthquakes; the largest Mag 2.5 in the past hour.


From the USGS earthquake page

What I find interesting is the location: Davis Lake Volcanic Field

The andesite scoria cones and lava flows in this area are younger than the Mount Mazama ash (7700 years ago), and are believed to be 5,050-5,600 years old. Young in geologic time, but no recent activity. All of the vents in the 15 km north trending line are believed to be formed from a single deep fissure.

The seismometers at nearby Newberry volcano pick up the activity fairly well. This link will take you to the PNSN spectrograms from Newberry.

It would be pretty exciting if any volcanic action developed.

ETA: This satellite image shows the nearby lava flows.

yep that was close,
both to me,
and to the fault with the epi-centre of NZ 's biggest recorded quake
Not on any known Fault though, in between two

another 500 odd felt reports since this morning

I was noticing that cluster & wondered about the volcanoes over there, thanks for linking all the info, good one to keep an eye on!!

Mt. Rainier also decided to rumble slightly.

Interesting considering she should have been asleep for another two weeks by now according to recent history. Also wondering if this movement is connected to the 4.8 that just occurred at Port Hardy.

Here is an updated cross-section of Mt. Rainier with the most recent activity.

a reply to: cynthius

It seems the activity in Oregon has captured the interest of the Cascades Volcano Observatory. The Pacific Northwest Seismic Network put out a nice write-up earlier today on their Seismo blog.

Any change in seismic activity increases our vigilance should the change develop into something threatening. This ongoing earthquake swarm southwest of Bend, Oregon, is just the sort of thing to trigger such vigilance. Because of the proximity of young volcanic vents in the area the Cascade Volcano Observatory is also taking an interest and as of today is installing an additional seismic station near the swarm.

There have been 43 reported quakes, although there could be many smaller ones not listed because the nearest seismometer is 33 km distant. Once the new equipment is in place, the earthquake locations and depths should be more accurate.

CVO reports that 2 previous swarms have occurred in this location: 6 earthquakes in 2001, and 20 quakes in 2012.

Finally, the PNSN concludes with this statement:

A large earthquake in this area is always a possibility or even a volcanic eruption. However, at this time both of these cases are considered very low probability events.

It seems unlikely for anything significant to develop, but I'm going to keep watching until it fizzles out.

Possible reason for omission is USGS has them lower at 5.7 and 5.5 repectively

I hadn't used this site for ages, for a quick Global overall view.
but just did, and seen this pattern


I hadn't noticed that Anti-Meridian International dateline dogleg kickout zigzag before!?
Didn't I get the memo?
Kind of weird how the Line Islands are +14hrs ahead of GMT, I always thought NZ had the biggest margin at +13 during Daylight Saving Time.
This came to notice this morning when I was planning to get up to watch the Rugby World Cup Semi Final live in London, South Africa vs NZ this morning. I had heard the match was on at 4pm GMT, but didn't catch the NZ scheduled broadcast time. We are in NZDST so assumed 5am NZDST. As it happened I woke up at 3:45 and flicked the TV on to check, damn they were singing the National Anthems already. I don't get it.
We won BTW.

actually that green trend line could have run right through to Vancouver Is M5 as well
of course the Planet isn't flat, so it's probably nothing.

Only the 2nd time this year we didn't have a M3 or higher in a 24 hour period , 23rd UTC, in NZ (grey, yellow or orange pie segment)


2hrs to go for the 24th UTC - 88 so far !, highest a 4.0

further to: muzzy post
But here is one I missed the other day;
It happened the same day as the one near me at Whitemans Valley and I didn't review the whole file or look at the map, I just posted it and moved on.
When I seen 88 quakes already for the day earlier this morning on the raw data I knew something was up, but there were no moderate quakes showing that would produce that many aftershocks, I thought it was a swarm of M1's; but no! it goes back 2 days to this one

Public ID 2015p796404
Intensity strong
Universal Time October 22 2015, 16:04:32
NZ Daylight Time Fri, Oct 23 2015, 5:04:32 am
Depth 15 km
Magnitude 4.5
Location 20 km north-west of Tolaga Bay
Latitude, Longitude -38.26, 178.12
www.geonet.org.nz...
120 Felt reports (Opotiki, Tolaga Bay to Gisborne)

There have been 34 aftershocks, but a weird pattern time wise.



There was also a 4.0 north of this series, but at 38km away I don't think you could include it. It looks like a general unsettling of the Gisborne/ East Cape Province in the last few days.

Hi muzzy, very weird. I never noticed that. I'm gonna go search and find out why that is.

Go NZ!!!

Have you ever seen this?

The pictures are awesome. Must be really cool to see up close.

a reply to: crappiekat

Muzzy when I was wandering around looking for info about the date line, I found this site.

mapmaker.education.nationalgeographic.com...

Is it something that would help you with the maps? I didn't try to play with it. I have got to be off to sleep.
