Sunrise on our last day in the field. We stayed in Sandstone the next night and visited a rock formation known as London Bridge, as well as the painted tanks that contain the town’s water supply. Stay tuned in the coming weeks for a short video on this trip. Thanks to GSWA for letting us come along.

We had time to stop to take in some sights today, despite the chewed sensor cable at one station near the vermin-proof fence that runs coast-to-coast north-south for thousands of kilometres. Some nights we camp at places we can’t light fires, but ambience is just two plastic buckets and a torch away

We’re camping at seismic stations in a remote section of the network. Flat tyres and camp fires - all part of the fun of field work.

First and only day I’ll be flying. Managed to get to 4 stations, deploy site characterisation nodes at each, and get some drone shots of a magnetotelluric station too.

I’m in Western Australia again, helping with mid-phase data collection from the instruments we deployed 6 months ago. We’re checking solar/battery and logger/sensor performance, and doing a little gardening. A busy 10 days ahead, with site characterisation and magnetotelluric surveys on the cards.

It’s #earthscienceweek so I thought I’d go into a bit more detail on how educators can use to our Quick Quake tool to demonstrate how @earthquakes.au seismologists quickly calculate the location and magnitude of an earthquake. It works on macOS machines with Apple Silicon too.

A magnitude 7.6 earthquake occurred about 10 minutes ago in the Mindanao region of the Philippines, triggering all stations in our southeast Australian network. It’s offshore and around 50km, so hopefully far enough to not cause too much damage or trigger a tsunami.

Here's the @auscope.bsky.social Seismometers in Schools recording this morning's M7.8 Kamchatka earthquake. Data and network visualisation is from SRC's Seismosphere.
The 24-hour single station view from Nhulunbuy in the Northern Territory shows the seismometer detecting the earth ringing for hours!

Is 200 earthquakes in just over a month normal for southeast Australia? It is, if your seismic network is dense enough and you’re dedicated to detailed data analysis. Staff at the Seismology Research Centre have manually located more than 35000 earthquakes over the last 50 years.

Another large earthquake just struck off Kamchatka, Russia. USGS reports magnitude 7.7. Energy waves now arriving in Australia.

This morning's magnitude 5.6 earthquake is the largest to have occurred in southeast Queensland since the magnitude 5.6 earthquake off Fraser Island in 2015. The Fraser Is quake was followed by magnitude 5.4 and 5.2 aftershocks in the following days, a reminder that further large events are possible

The wiggly lines of a seismogram can sometimes hide small but important signals at other frequencies. This is why we also look at spectrograms!
Interesting recent recordings include #kangaroos #rockfalls #sonicbooms from meteors & rockets, and crowds at #football #travisscott & #taylorswift concerts

Some schools can get involved with Science Week by looking at their seismographs to see the magnitude 6.1 earthquake that occurred in West Papua an hour ago. There are about 50 schools across the country with an @auscope.bsky.social seismograph. Here's what they recorded, as seen on Seismosphere

Yep, there it is! Recorded at a station north of Daylesford.

Let's see is we can find this non-earthquake on our seismographs! Last week we detected the NSW rockfall, and last night a meteor shook houses in central Victoria.

A colleague noticed this Facebook post about a massive rockfall in the Blue Mountains, so I looked at the overnight records to see if it was visible. The closest station was 30km away, and a spike in the spectrogram at 3:05am had me check other nearby stations, which all rumbled for about a minute.

I grabbed the spreadsheet from volcano.si.edu and plotted the date of each eruption (since 1900: 🤪Excel) versus the duration (not severity) of the eruption. For readability I clipped it at 10K days. One in Guatemala started in 1922, only ending last May! Those on the sloped edge haven't yet ended.

I received a comment about feeling like we're getting more magnitude 6+ earthquakes lately. It's funny how recent news can influence our perceptions. Here's global M6+ earthquakes for the last 25 years, and zoomed to the last 3 years. It's human nature to look for patterns. What do you see?

This is why we use 3D sensors in earthquake data analysis. I selected a seismogram that highlights how the vertical channel has a clearer P-wave onset. The S-wave arrival on this channel is really unclear compared to the horizontals. Low-frequency high-energy S-waves are often the destructive phases

Could a larger earthquake follow the M8.8 at Kamchatka? It would be unprecedented, but megaquakes have had similarly sized aftershocks in the past: an 8.3 at the nearby Kuril Islands in 2006 was followed by an 8.1 two months later; and an 8.0 in PNG in 1971 was follow by an 8.1 just two weeks later.

I missed a lot of today’s major earthquake action while out in the bush doing off-road driving and recovery training. Great course run by 4WD Victoria. Now I’m getting up to speed with the earthquake and tsunami for a bunch of impending interviews.

Finally getting official 4WD training! It’s great fun trying out all of the modern electronic features in a safe and stress free environment before needing to use them in the field with the @earthquakes.au vehicle. My colleague Wayne even let me have a go in his personal Suzuki Jimny. Very cool
