I’m at a dam and climate conference in India, and I had never heard the acronym GLOF before, but it’s definitely the buzz word here.
We need more flowers at our meetings. It’s an impressive display, and rather calming.

2025 earthquake recap. Guess how many.
Interesting that Victoria’s largest earthquake was a single magnitude 3 earthquake last year. Remember only a few years ago when it seemed like Victorians were feeling an earthquake every few months? That’s the dynamic earth for you.

It’s the 50th anniversary of @earthquakes.au and it all started when I was 5 years old with a magnitude 1.4 near my house. How cute was I?
Congratulations to everyone who has contributed to the success of the SRC over the decades, and to those taking Australian seismology into the future.

Have you got something to share with the seismological community about making STEM more accessible? I’ll be talking about how software developed by @earthquakes.au is helping students and early career professionals analyse data. Join this session at the @seismosocam.bsky.social meeting this April.

2025: the year when the first fault rupture was captured on video. Onshore, large, surface rupturing earthquakes are so rare, and to have a camera recording that close to the rupture and framed so well is potentially a once in a lifetime event.

When I posted a version of this video last year, I underestimated the equivalent energy of a magnitude 9.1 earthquake relative to a nuclear blast by a factor of 10. This time I’ve quantified it using the Trinity test (as seen in the movie Oppenheimer). The 1957 underground test was 10x smaller again

My last trip to Western Australia wasn’t just to collect seismic data, but also involved setting up magnetotelluric stations and deploying networks of nodes to characterise the velocity profile at each site. It was nice to be able to use my drone to get a different perspective of our field work.

Faultless earthquakes? Several recent earthquake swarms in southwest Western Australia appear to be volume rupture sequences that don’t appear to occur in a plane to indicate a faulting structure, even after HypoDD reanalysis of 400 aftershocks.

It’s concert season in Melbourne. Last weekend Lady Gaga was rocking Marvel Stadium hard enough to shake our office seismometer 5.6km (3.5mi) away. Here’s the set list order plotted next to frequency and ground motion over time.

First hand proof: Lenny Kravitz got Melbourne jumping last night! I correlated my video timing with the seismic recording. He’s so cool, and equally hot. Lenny is all the temperatures.

HypoDD visualisation!
Last week I presented a paper on the reanalysis of an aftershock sequence using the double difference method, and used this animation to show how the event locations moved in depth and lat/long with each iteration. About 450 events, with a stable result after only 4 iterations.

I was genuinely surprised at the AEES conference dinner tonight when the committee presented me with lifetime membership to the Society, joining only 5 others given this honour in the Society’s 35 years. I’m scaling back my AEES duties for a few years, but I’ll always be lurking in the background 🤓

AC/DC played Melbourne again on Sunday night. There was a 12% higher peak in ground-pounding tunes compared to last Wednesday. The frequency "heat map" pattern was similar in timing and relative intensity, but slightly clearer this time. 🤘

AC/DC shakes Melbourne! It seems more energy waves went into the air than into the ground, with people reportedly hearing the concert up to 7km (4 miles) away. The ground energy was detected, but not as strongly as during some other recent concerts #ACDC #taylorswift #oasis #travisscott #kiss

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.
