We recorded two non-earthquakes in the last 24 hours. The first was on our office seismograph, detecting Oasis fans 5.5km away at Marvel Stadium. The second was picked up by our station in eastern Victoria - likely a sonic boom from a meteor. The sound was reported widely in the region.

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!

ABC News Breakfast asked me to drop by to comment on this morning's M7.8 earthquake, an aftershock on the M8.8 from late July. I think I'm getting better at explaining crustal stress in plain language, but then I go and call Kamchatka an island instead of a peninsula🤦♂️

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.

Question for earthquake instrumentation people: what's the distinction between a "Low Gain" and a "High Gain" Seismometer?
What's the V/m/s level above of below which we define the Instrument Code as H or L?
Old school passives were generally under 400V/m/s. Is that it?

What’s a funny or clever collective noun for your (or any other) occupation? Make one up in the comments, or like the one in there that you think is the best so far.

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

I think I’ve got you all, but if you’re a seismologist that’s following me and I’m not following you back, let me know with a like. Sometimes I miss notifications or don’t notice the role in a bio.

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

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.

I’ve been wanting to get this into the wild for ages, and we’re almost there. Hopefully this will make our software even more accessible and useful. More features and fixes coming too. This is just a sneak peek.
Waves of Colour! There’s a new version of Waves coming that brings dark mode, amplitude based waveform colours, and 42 options for the spectrogram colour scheme. Waves is a free app anyone can use for waveform analysis and earthquake location and magnitude calculation. www.src.com.au/downloads/wa...

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.

Probably a good time to do this:
*Do people have questions about earthquakes?*
We have a lot of seismologists on Bluesky and we are very willing to answer whatever questions you might have....

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?
