GEOFON notification system at the GFZ German Research Centre for Geosciences has calculated and notified a fewminutes 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:

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
