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

Wow, I did not expect my little observation to make its way outside Australia and get picked up by @billboard.com and @rollingstone.com 🤘

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?

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
