Pretty clear signal on my Raspishake seismometer which is about 8600 km away in Herne, Germany. The seismometer just sits on Top of my kitchen. ⚒️

Lots of earthquake activity in Alaska today (SW of Adak) with five earthquakes above M5 since 11 am local time.

A M6.3 and M6.1 #earthquake occurred last night at 2024-12-09 00:15:31 and 00:38:53 (UTC) at the Aleutian Trench (the trench that connects Alaska, USA to Kamchatka, Russia).
Both earthquakes can be seen in the middle waveform and form part of a larger earthquake swarm happening in the region.

M 7.0 #earthquake 63 km WNW of Petrolia, CA as displayed on my Raspberry Shake in #Edinburgh. USGS details: earthquake.usgs.gov/earthquakes/... Hope all are safe.

Here’s the filtered seismogram from my Raspberry Shake. I’ve had running 24/7 for 7(?) years now. Its awesome.

The UK now has more citizen science raspberryshake seismic stations than professional ones. Some detect surprisingly good signals from 8000km away, even with sub-optimal sites tgey see big events. R94C3 is in my garden office (aka the shed) and detected P waves from todays California earthquake ⚒️

I quickly put together a seismicity map for yesterday’s M7.0 earthquake and its aftershock sequence (purple outlines), which gets very close to the coastline. This transform also represents an impressive bathymetric feature. 🧪⚒️

Nov. 20, 1933: A M7.3 earthquake struck offshore Baffin Island, #Canada. This is the largest known #earthquake along the passive margin (east/north coasts) of #NorthAmerica and north of the Arctic Circle.
