North Korea claims to have hydrogen bomb for long-range missile

a reply to: violet

The problem is an explosion and an earthquake look nothing alike.

If they say they cant determine which it was it means theyre holding back info. Any seismologist will be able at a glance tell if the chart depicted an earthquake or an explosion. Theyres no confusion. If theyre confused then they are playing dumb.

That's what I thought

Earthquakes have shearing waves. A large up and down motion. Its long and protracted.

Explosions are compression waves. Its short and compact.

Earthquakes go up n down for a duration. Big squiggles. Explosions show a compression wave traveling through the ground after a very large initial spike. They look nothing alike.

True.

For example. Like this right?

If I understand well, only the P-wave, no S-wave trailing behind?

Anyone have a seismogram source not far from NK, just finding stations in America, and since S-wave cannot travel inside molten material...

ETA: OK, found somes data, computing now...

Well it registered as 6.3 on the richter scale

M 6.3 Explosion - 22km ENE of Sungjibaegam, North Korea

Possible explosion, located near the site where North Korea has detonated nuclear explosions in the past. If this event was an explosion, the USGS National Earthquake Information Center cannot determine its type, whether nuclear or any other possible type.

Ok. And the point was ?

a reply to: Cofactor

Exact reported time of event: 2017-09-03 03:30:01z

Spectro location: Mudanjiang about 400km distance from event

P-wave ~5km/s -> +80sec -> 03:31:21z arrival

S-wave ~3km/s -> +133sec -> 03:32:14 arrival

Spectrogram at Mudanjiang show P-wave at 2017-09-03 03:30:53z and strong S-wave at 2017-09-03 03:31:34z

Either it is not an explosion or there is more to it...

Can't vouch for the legitimacy of these, but figured I'd pass them on...

CONFIRMED: North Korea has just detonated a 1 Megaton (1 million tons of TNT) thermonuclear warhead, triggering a 6.3 magnitude earthquake

North Korea says it will make a big announcement at 3:30 pm, Japan time

It's interesting that Secretary of State Rex Tillerson applauded North Korea yesterday morning for showing "remarkable restraint". Today NK scrambles egg on Rex's face.

Looks like Fox took down that second earthquake alert, wonder where they got that information?
That was scary and apparently fake news.

This is not fake news, it is Fox News, much worst.

They removed that alert because it's "old news" now. Things are moving very fast. This live blog will keep you up-to-date. An announcement from North Korea will be streaming live through the blog in a few minutes.

One megaton seems like a quick upgrade from last year? Somehow not doubting it, having seen projected graphics in the past.

Also, just seen this source from a thread shared:

The shockwaves were at least 10 times as powerful as the last time Pyongyang exploded an atomic bomb a year ago, Japan’s meteorological agency said. The previous nuclear blast in North Korea is estimated by experts to have been around 10 kilotons.

Same time from this source:

North Korea's state-run broadcaster said there will be a 'major announcement' at 3pm Pyongyang time (2.30am ET/7.30am GMT). Source

Apparantly Japan's seismologists are saying it was nuclear.

Seismologist in the first "tests" did too....until they found there was no residual radiation. It would be very rare for a seismologist to determine that on their own. They could base it on old post WW2 shockwaves. But that would not necessarily mean any form of nuke test.
We shall have to wait and see .
Let NK perform underground tests in their own country . Above ground tests would be better for them . (being facetious now) .Irradiating their own water table and wasting their resources. Thats what stupids do.

Ok amd I hope you're right
