Quake Watch 2015

a reply to: historykel
No not based on comaprison with last year, in the 8 months so far on the planet in 2015 there have only been 1071 earthquakes above M5.0 versus 1171 earthquakes above M5.0 in 2014 same period (EMSC data). The Ring of Fire is probably something like 90% of the earthquakes at any time.

a reply to: muzzy Something up here with earthquakes location Aluetian Islands many in a row. Working up to something?

a reply to: historykel There has been 38,528 earthquakes in the past year, I do not discriminate between mags, but trackers do not even account really for anything under 3 when put in data. I wouldn't know how to go back and tell numbers from years before, but all ready learned that volcano's around ring are very active, so that would lean towards more earthquakes in the future. At least the probability is there.

a reply to: historykel
Like in 2011 if we were to go back to activity, well the list just the very top is long and that is not all the names you can delete this afterwards if its a nuisance.

Ambrym Island, Vanuatu
Aoba, Ambae Island, Vanuatu
Aso Kyushu, Japan
Bezymianny, Kamchatka, Russia
Bulusan, Philipphines
Cleveland, Chuginadak Island, Alaska

Manam, Papua New Guinea
Merapi, Indonesia
Marapi, Indonesia
Nevado Del Hila, Colombia
Nyiroagongo, Congo(Dem. Rep.)
Even Mount Saint Helens.. sure they get active but they say its increased of recently and with your input that its a cause to earthquakes with out any evidence backing it up, well would only validate saying more earthquakes to come.

a reply to: historykel
Why stop at 3 ?, there are probably three times as many more earthquakes below 3 than there are over 3, especially as you seem to be focused on volcanic earthquakes, most of those are below M1.
there are still earthquakes where there are no volcano's, it doesn't always fit your scenerio that more eruptions mean more earthquakes or vis versa.

The USGS estimates that several million earthquakes occur in the world each year. Many go undetected because they hit remote areas or have very small magnitudes.

Source: (Obsolete page as not recently updated) Earthquake Facts and Statistics

I do not discriminate between mags

Most observers look at the larger magnitudes bearing in mind that 1000 mag 3 quakes = mag 4 and 32000 mag 3 quakes = mag 5. A typical list of 6.5+ stats

Given the huge number of smaller magnitude quakes in terms of energy that go to make up a single larger quake you should indeed tale account of magnitude as it is very significant. You are very unlikely to get volcanic quakes over mag 6, where as only tectonic quakes over mag 6 have any real significance on the ring of fire. Lesser mags perhaps may be significant outside the ring of fire.

Earthquake activity and volcanic activity at this time are well within normal, if there can ever be a normal, and in fact possibly on the low side. This may be accounted for by the extremely low solar output at this time which is currently insignificant for such a short period after solar max, and we are set for a blank sun probably in the next few years with attendant lower global temperatures and reduced earthquake activity. If that is the case the solar link will have been validated.

The USGS have upgraded two eartquakes giving us one addition mag 6 in August:

2015-08-06 23:59:45, -26.457, -178.251, 6.0, 269.0 South Of Fiji Isls. (171)

and the first September Mag 6

2015-09-01 15:25:09, 31.172, 141.600, 6.0, 7.3 SE Of Honshu. Japan (211)

The first link on each is to USGS the second to google maps.

I'm just linking to the most current one:
earthquake.usgs.gov...


Something is up. There is also some quakes on the Russian side.

yep darkblade. I dont usually reply on Quake threads, but seeing a lot of activity here.

USGS has currently 73 x 2.5+ quakes which is the highest ive seen for a long time. Im sensing a biggie incoming soon.

a reply to: PuterMan
thats an interesting site, lots of lists, especially interesting to me as I'm mapping the from same magnitude baseline 6.5
however
straight away we are at odds,
2015 the first quake is Vanuatu on that site
what about the 6.5 at Panama before that?
perhaps (very likely) the neic (usgs) has downgraded it since then?

Its all very well and good, they seem to have done a lot of research work, and it seems to update automatically by the look of it.
But at the end of the day if you look at 2011 for example, because it is limted to 6.5+, what is missing are the 2011 Christchurch quakes of 6.3, 6.4 and 6.0 that destroyed a city of pop. 250,000 and and killed 36 people.
A couple of days ago was the anniversary of the one that started that series, the 7.1 Darfield, there are some people who are still waiting to settle with their Insurance companies, people still living in caravans.
Same applies to China, there are many earthquakes there below 6.5 that have killed 10's if not 100's thousands of people, but they are not on the list.

overall though its a pretty good site, with the summaries etc.

Median Tectonic Line, Japan. link
I found a new template on Wordpress, that's a bit like the one on Blogger that I use for NZ and Japan. It's not flipcard, but you can overview the whole lot, then with 2 clicks get to the full size image map 1278 pixels wide.

More micro quakes at BUNGO CHANNNEL and also spilling into SW EHIME PREF now

The other cluster to the east is NW WAKAYAMA PREF, it's always on the daily map, not sure why, it may be (coal?) mining. Need to check that out.
2824 in all of August, average 91 per day
404 in the first 4 days of September, because of Bungo, average 101 per day over the whole area.
SW SHIZUOKA PREF is in there last week, but like HAKONE back in Apr, May, June, it would be hard to see the dots on the large static map anyway as they were so concentrated.
That has made me decide to make interactive Bing maps as well. The link for each day will be at the bottom underneath the static image, so readers can zoom in. (I have done 01082015 as a test).

Not everyones cup of tea, such small quakes, but we get them here too in the Lower West Coast of North Island, NZ and over on the East Coast, NZ and it has been speculated that the last slow slip event here was equal to a magnitude 7 if it had gone off in one big movement. Pacific North West USA/Canada also has this going on.

thats it for today. got other things to do and need some sleep afterwards. I'd say keep an eye on the eastern side of North and South America and asia.

a reply to: Eagleyedobserver
sleep?
how can you sleep at a time like this?
LOL just kidding.
I had a bit of a nap myself this afternoon, nice day here at last, so sat out on the patio, fell asleep in the chair in the sun. Woke up I thought it was summer. It's the 4th day of Spring.

Andreanof Islands
interactive Bing Map with sequence numbers.
On the graph below, the Black data points and lines are the Western part, and the Red part is the eastern part of the Swarm.
Data is directly from USGS download csv file off their map page, so it WILL change (locations and magnitudes), thats guaranteed.
Is it over? looks like it, but these things are so unpredictable, it could go nuts and put out some more 5's yet, even a 6 or 7.
Its gotta go somewhere soon.

there is about a dozen bunches worth looking at closer, job for another day.
