Power spectrum (MEM) of micro-seismicity shows average during one hour (black)
and nine sliding 20-minute slices with ten minutes'
report (from yellow, early, via red
to purple, late). The pyjamas pattern aims to relate frequency to
source area:
▉Greater North Atlantic,
▉Biscay,
▉Celtic Shelf,
▉Norwegian Sea,
▉North Sea.
