GEOFON notification system at the GFZ
German Research Centre for Geosciences has calculated and notified a few
minutes after the origin time at 01:30:01 UTC time (10:00 Pyongyang time)
a magnitude of M 5.3 for this event. The location of the event is almost
the same as the previous known explosions in 2013 and 2009.
Seismic signals from explosions are different from those observed in case
of earthquakes showing particular features that allow seismologists to
distinguish between the two.
Information about probable hydrogen bomb test in North Korea derived from seismological observations
06.01.2016: A very shallow seismic event was detected this morning in North Korea
near Punggye-ri. The automatic GEOFON notification system at the GFZ
German Research Centre for Geosciences has calculated and notified a few
minutes after the origin time at 01:30:01 UTC time (10:00 Pyongyang time)
a magnitude of M 5.3 for this event. The location of the event is almost
the same as the previous known explosions in 2013 and 2009.
Seismic signals from explosions are different from those observed in case
of earthquakes showing particular features that allow seismologists to
distinguish between the two. The similarity of the waveforms, the
shallow depth and the almost identical location with respect to the
previous events in 2013 and 2009 are indicating that also the source of
this event is an explosion. A comparison with the measurements from 2009 und 2013 shows a larger magnitude of the 2016 test.
The GEOFON station of GFZ at Flechtingen in Germany recorded the event eleven minutes after the origin time in a seismogramme:

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
