Earthquakes: Cross-correlation detector in #ObsPy is used to match a template from one seismic event to a longer trace from a seismometer, returning events which correlate above a user-defined threshold. Applying this to
#RaspiShake RD884, in Constantine, Cornwall, UK at a threshold of 0.80, I have identified 33 separate events in a swarm of multiplets (or repeaters) from the last week, identical earthquakes produced repeatedly from the same source. 12 of the events from this swarm have also been reported by #BGSSeismology. The largest event has a magnitude of 1.7, so they are all very small, although the M1.7 event was felt at the surface. The #ObsPy tutorial I followed is here: https://docs.obspy.org/master/tutorial/code_snippets/xcorr_detector.html and
#BGSSeismology report the swarm here: https://earthquakes.bgs.ac.uk/earthquakes/recent_uk_events.html.

Magnitude 5.4 #earthquake in the #SolomonIslands It is a bit offshore so hopefully not dangerous - too small to generate any significant tsunami.
Signal at the very close station IU.HNR (about 60 km away) obtained from #IRIS using #obspy software (@obspy)
There are several smaller aftershocks if you look carefully at a longer data segment. I will leave that as an exercise for you!

Magnitude 4.5 #earthquake in the remote far North East of #Canada about 90 minutes ago (2022-11-19Z10:24) Signal at station CN.POIN (Pond Inlet, Canada) Data courtesy of #NaturalResourcesCanada and obtained from #IRIS using #obspy software ... only the lines of python you see.
High regional signal with regional P and S phases (about 100 km distance).

I should have acknowledged that the plot is a time frequency representation created using the plot_tfr function in #ObsPy.

We're finalizing a new #obspy feature release version 1.4.0, which will get tagged during the next couple of days.

If anybody wants to test it, release candidate is on test.pypi:

https://test.pypi.org/project/obspy/1.4.0rc3/

Two tiny #Earthquakes reported in #Cornwall, UK, on 2022-10-25 in Penpol on the Fal estuary and 2022-10-26 near Portreath on the north coast. Responses were seen on the local #Raspishake network. See: https://earthquakes.bgs.ac.uk/earthquakes/recent_events/20221025184145.html#page=summary & https://earthquakes.bgs.ac.uk/earthquakes/recent_events/20221026192120.html#page=summary. Uses #ObsPy & #MatPlotLib.

M5.2 #Earthquake 23 km ENE of Dipayal, Nepal at 2022-11-12 14:27:05UTC recorded on the Nepali Schools #RaspberryShake network in Nepal. See: https://earthquake.usgs.gov/earthquakes/eventpage/us7000ipbc/executive. Uses #ObsPy, #MatPlotLib & #GoogleEarthPro.

Magnitude 5.3 #earthquake in #Nepal almost exactly one hour ago (2022-11-12Z14:27). It comes four days after a 5.6 which caused significant damage and several fatalities. It is a reminder that earthquake hazard is not dominated by the very largest earthquakes - they are few and far between. The most lives are taken by "medium sized" quakes.

Responses to today's M7 earthquake from the Fiji region at 2022-11-12 07:09:14UTC recorded in SW England and Brittany, France on the
#raspishake and #BGSseismology networks. See: https://earthquake.usgs.gov/earthquakes/eventpage/us7000ip8h/executive. Uses #obspy, #matplotlib & folium libraries.

Selected responses across the British Isles to today's M7 earthquake in Fiji 2022-11-12 07:09:14UTC recorded on #raspishake citizen science seismometers, plotted using #obspy, #matplotlib, folium.

Section from today's M7 earthquake in the Fiji region at 2022-11-12 07:09:14UTC recorded across the globe on the #raspishake citizen science seismometer network. See: https://earthquake.usgs.gov/earthquakes/eventpage/us7000ip8h/executive. Uses #obspy, #matplotlib
.

@freemo at well as downloading and playing with #obspy, which is highly recommended, you can see professionally produced versions of this plot, using more seismometers at #iris here: http://ds.iris.edu/spud/eventplot/20633642 and lots of further information from them here: http://ds.iris.edu/ds/nodes/dmc/tools/event/. My plot uses citizen science data collected from many private #raspishake seismometers across the globe.

Today's M7.3 Tonga region earthquake at 2022-11-11 10:48:45UTC recorded in the British Isles on the #raspishake #seismometer network. See: https://earthquake.usgs.gov/earthquakes/eventpage/us7000ip0l/executive. Uses #obspy, #matplotlib & folium libraries. Waves travelled via the core.
