This was a significant earthquake, with seismometers on the other side of the globe detecting seismic motion.

I believe (and I'm no expert) that the descending frequency from a high of 100 kHz to a long trail at 50 kHz is the chirp of a #pipistrelle, probably a common one. 🦇🦇🦇 #bat

No major damage has been reported in the region.
Rare for this station, both the P and S wave arrivals can be seen in the unfiltered waveform.

The focus point (hypocenter) of this earthquake was deep at 243 km depth, which is not uncommon for the region.

For some perspective, if the latitude was flipped, the location would be on the same latitude as Scotland.

The arrival of the seismic waves from the earthquake are displayed here on a seismic section, with the predicted phase arrivals overlaying the seismograms.

The signal is clearest using a low frequency bandpass filter (bottom/red waveform), which removes most anthropogenic (human-based) ground motion from the seismic waveform.

The earthquake was produced from a normal fault, likely relating to the Himalayan collisional zone. Aftershocks in the region of ~M5.0 have been detected.
