Hey Muzzy,

Was curious if you heard of this theory?

Earth is now in a seismically active period according to quake cluster theory

Following the second major earthquake that hit Nepal on 12 May, some scientists believe we could be seeing a seismically active period that began in 2004 and could end around 2019.

Great earthquakes of magnitude 8.5 or higher occur infrequently but are found to cluster in time, says Chadha, based on the analysis of 115 years of global data. Such "clustering" is not found for magnitudes lesser than 8.0 which show an annual average of about 15 to 16 every year, globally.

Data analysed from 1900 onwards based on the catalogue available with United States Geological Survey (USGS) indicate there have been three possible periods of clustering of magnitude 8.5 or greater, lasting 15 years, which can also be referred to as "periods of seismic activation" of great earthquakes, he told IBTimes UK.

I tend to be skeptical about this since they only used 100 years and why not try to look back farther? Wanted your opinion on it if you had time.

Not sure you have read about this also?

‘Drumbeat’ volcano earthquakes triggered by external noise – study

The Yekaterinburg team decided to test a mathematical model of this stick-slip motion, but also added another factor – outside noise projected onto the volcano.

What they found was revealing – not only did the noise contribute to the oscillations, but relatively small sound waves could produce a disproportionate destabilizing effect, with the volcano seeming to dance to the beat of the white noise coming in from outside.

The team now hopes to apply their findings in a practical area – forecasting eruptions, by understanding the mechanisms within volcanoes. They admit, however, there are still too many variables to be able to use mathematical models like theirs to predict real eruptions.

Outside noise triggering a volcano?

thanks for your time.

Hakone still popping, 97 events of the 18th JST, 3 of them M2's, still nestling at the north end of Lake Ashi.

Seems to have eased off on the 19th, only 39 events.

May be over, only 19 events on the 20th, all micro's


I'll see if I can get that animation and a graph done later today.

Hey Muzzy mate.

Just did my usual check on RSOE.

I do not remember ever seeing New Zealand quite this busy. Lots of smaller EQs

Is it just me or is something up?

Alaska is also busy although that is not unusual.

I do not remember seeing a quake so close to England. I expected it to be far out at sea, but no, it was not. Very unusual.

That's pretty close to home, I'm in Sacramento.

More activity in CA. There was a 4.1 near the Salton Sea yesterday which started a mini swarm

a reply to: muzzy

Muzzy,

I wanted to ask you were did puterman go? I miss his post about eq's.

Thanks in advance.

a reply to: SkipperJohn
I think he is just busy with other stuff.

a reply to: pheonix358
Not that I noticed, usually about 50 per day M1+
I haven't checked for today yet, just back home now.

a reply to: dreamfox1
Thats a pretty big one for the UK.
no second line

a reply to: lurksoften
I hadn't heard of a specific theory like that, but the time period is way too short to be able to say such a thing IMO, how many M9's in 100 years? 6?
Depends how you twist the data I guess.
I'll do a graph when I get a minute, time versus magnitude, that should show it right away
count them yourselves
the whole list of M8+'s is there too

just checked
Not sure what time span you were looking at on RSOE, but today was one of the lowest numbers this year, 28.
But 7 of those were mag 3's, so the radiated energy released was "safe" at 27.65TTNT (below 6TTNT is "unsafe", as it means pressure is building)

a reply to: muzzy

Thanks Muzzy. I don't think RSOE reports on mag 1 and below. So it was the high number of bigger ones that caight my eye. Thank you for the reply. I appreciate it.

Geologists from Brigham Young University, Berkeley Geochronology Center and the Pacific Northwest National Laboratory have found evidence of twenty ancient supervolcanoes near the Utah-Nevada border.

The team also found evidence of 15 super-eruptions and 20 large calderas – the so-called Indian Peak-Caliente caldera complex.
These supervolcanoes have diameters up to 60 km and are filled with intracaldera tuff and breccias. They have been hidden in plain sight for millions of years despite their enormous size.

Vegas here. Didn't feel a thing.
