Something fishy going down in Melbourne Aus… supposed 'earthquake' last night that definitely felt like a boom, have experienced a few quakes before and this was not a quake. Instant full scale thumb with an audible subdued boom (like it was underground) and then only short following shake.
Found the seismic graphs on gov site and confirm what was felt.
4.2 at 3km deep…. suss af, and those i've talked to all said the same thing, didn't feel like a quake.
