Earthquakefag here

Usually Iran has a shit ton of earthquakes in the Zagros Mountains, but this one is interesting. 9/23/18 4.4m 8km deep, looks like a cave-in or explosion (compared with NK waveforms and tech info from nuclear tests). Definitely not quarrying or fracking (too big of a shake). Check out the area, It looks like a crater from a ground implosion maybe from a previous "quake." The area in near Shiraz AFB and there have been a few questionable quakes under the mountains nearby. However the nearest sensor station is in the UAE so it's tough to decipher some of the Iran quakes.

One more:

This one is for the Antarcticfags out there… a rare 2012 4.9m earthquake in Antarctica in 2012 under the Ross Sea.

So it was originally labelled as an anomaly, then as a possible volcanic eruption from nearby Mount Cerebus (an active volcano but no seismic activity since 1983); sediment displacement underneath the Ross Ice Shelf (um, no), and then giant pieces of the ice shelf breaking off into the ocean due to global warming. Either way, it was felt all the way in Australia and because there were no supporting aftershocks it is an anomaly. Not saying this one is an explosion, but the seismic waveform does looks like a massive cave-in (under the ice). Agartha?
