Definitely more than 70, but not all can be felt. GSWA field staff were easily feeling magnitude 2+ events while installing the seismographs. Nice to see the 24-hour "drum" image from the @earthquakes.au Seismosphere system featured. Data visualisation at its best! www.abc.net.au/news/2026-02...

There is an active earthquake swarm near Gnowangerup in Western Australia. Here is the last 24 hours of recordings from one of GSWA's Rapid Deployment stations. Of yesterday's several hundred earthquakes, the largest on screen was only M2.5. A magnitude Mw5.0 earthquake occurred in this area in 2023

One of the quietest periods for a while - only 19 earthquakes detected in southeast Australia last week. Meanwhile in the west, our friends at GSWA are installing rapid deployment kits to capture yet another swarm in the southwest, this time near Gnowangerup. Tiny pops are visible every few minutes!

Did you know that last year there was only one magnitude 3.0 quake in Victoria, and it was the state's largest for 2025? A magnitude 3.1 earthquake near Dargo in early Feb 2026 is the largest in the state this year, with the region's hills shaken hours later by an M2.8 about 100km to the southeast.

At 8:38am we detected a magnitude 2.8 earthquake north of Dargo in eastern Victoria, and another of similar magnitude just occurred at 5:02pm, about 110km to the southwest of this morning’s event, north of Moe/Morwell

If this is the first time you've seen one of our earthquake maps, welcome! They are routinely posted, but may not contain any notable activity. They exist to show that we are not without earthquakes in southeast Australia. This one is from 19 January to 1 February. Largest magnitude was a 2.4 in NSW

A dozen of last week's 37 earthquakes all occurred in a 22 minute window - a tiny cluster in the mountains of Errinundra National Park in far eastern Victoria The largest earthquake for the period was a magnitude 2.0 near Cadia NSW.

Here's 107 holiday break earthquakes, from 22 Dec to 11 Jan. The largest in South Australia (within the map area) was a magnitude 2.8 on Dec 29 near Parachilna. The largest in NSW was a 2.6 near Cootamundra, and Victoria's largest was 0.6 and one syllable smaller: a 2.0 and near Inverloch.

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.

This is the last weekly map update until 2026, but stay tuned for earthquake information posts if something notable happens over the holiday break. Last week we detected 36 earthquakes, the largest being a magnitude 2.7 located about 25km northwest of Warracknabeal in western Victoria.

Last week a magnitude 4.0 earthquake occurred near the Oodnadatta Track, about 50km west of Marree, SA. This is the seventh M4+ earthquake in the map area so far this year. A magnitude 2.8 quake occurred near Lake Eildon, VIC. Activity continues off Tasmania's north coast after the M3.3 on Nov 30.

8 years ago we made our earthquake data analysis application, Waves, free to download. Prior to that it was in the hands of just a few hundred users. Since then it's been downloaded almost 25,000 times! Windows dominates, but we also have it available for macOS (Intel & Apple Silicon) and Ubuntu.

Three offshore magnitude 3+ earthquakes occurred in the region last week: 🟠On 24 Nov a magnitude 3.2 quake struck off West Point in northwest TAS 🟠On the 29th an M3.5 occurred off the NSW south coast, 35km east of Bermagui 🟠On the 30th an M3.3 occurred 10km offshore, ~60km north of Launceston TAS

Limited stock and sizes remain, so get in quick if you want a MegaQuake t-shirt. Free shipping deal is on between now and 18 December, so get in early if you want one to arrive in time to put under your tree these holidays.

The two largest earthquakes last week were a magnitude 2.3 near Broken Hill, and a 2.0 near Cadia NSW. To those commenting that we are being dramatic by calling these "earthquakes": this is the only precise term. They just vary in energy. Tremor or shake are unofficial terms used help orient readers

In the last week we have detected 37 earthquakes in the map region, which is about average. The largest was just off the Tasmanian south coast at magnitude 2.9, followed by two near Cadia NSW (2.4 & 2.3), two in South Australia (2.3 off Seaford, 2.2 Flinders Ranges), and a 2.0 near Tynong VIC.

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. 🤘

Here's the last two weeks of earthquakes in southeast Australia. The largest was a magnitude 2.7 near Broken Hill NSW. If you hadn't noticed them before, the grey dots in the background of our maps show historical epicentre locations, mostly from the last 60 years, but some from as far back as 1788!

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.

A magnitude 2.5 earthquake northwest of Armidale NSW was the largest of 35 events last week, followed by a 2.2 off Kangaroo Island SA. There’s also a 2.0 amongst the four earthquakes that occurred within a 15 minute period near Bonnie Doon VIC early this morning.

A light scattering of earthquakes across the states, with the largest last week only magnitude 2.3 near Adaminaby NSW, just south of the Australian Capital Territory.

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.

Earthquakes for weeks 40 & 41 - only 50 events to report, which is a little less than average. Only one earthquake cracked the M2 barrier: a magnitude 2.1 on the 10th of October at 8:12pm local time at Dalton NSW, just north of Canberra. #earthscienceweek

42 earthquakes were detected in southeast Australia between the 18th and 28th of September 2025. The magnitude 4.4 near Strathgordon in Tasmania was the largest onshore earthquake in the state in over 20 years, when an M4.5 occurred at Cradle Mountain in November 2004.

Preliminary info: a magnitude 4.4 earthquake has occurred near Strathgordon in southwest Tasmania

Here are the 83 earthquakes detected from 1-17 September. NSW decided to host the M3+ events this time: two magnitude 3.7 earthquakes occurred 370km apart but within hours of each other, one near Nyngan, the other near Muswellbrook. An M3.1 then occurred 5 hours later 135km east near Bulahdelah NSW.

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.

It's been a while, but we're back with our earthquake map! Here are the 213 events we detected from July 21 to August 31. The two largest were on Kangaroo Island in South Australia: a magnitude 3.6, followed by an M3.2 two weeks later. The other magnitude 3.0 was on Melbourne's Mornington Peninsula.

Did anyone in Sunbury feel this little earthquake just before 9pm?

A magnitude 3.0 earthquake occurred at 11:35am today on Kangaroo Island, South Australia. This follows a magnitude 3.6 that occurred on the island about 2 weeks ago.

#earthquake #gympie #queensland #brisbane

Preliminary info: magnitude 5.3 earthquake near Gympie in Queensland at 9:49am

A magnitude 2.9 earthquake occurred just off the east coast of Melbourne‘s Mornington Peninsula at 4:39am, near Flinders.

A magnitude 3.4 earthquake occurred on Kangaroo Island in South Australia at 1:32am today. Report what you felt at earthquakes.ga.gov.au/feltreport

Seismosphere is a cloud-hosted data visualisation and seismic network management tool that we designed to run our observatory, and we’re proud to be able to help other organisations share their data using this user friendly platform.

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.

Glad to be able to share a bit of knowledge about earthquake and tsunami monitoring on ABC News Breakfast this morning www.facebook.com/breakfastnew...

My thoughts on the recent M8.8 earthquake sequence and tsunami, with my NZ colleague John Townend @vicuniwgtn.bsky.social @earthquakes.au @monashuniversity.bsky.social theconversation.com/kamchatka-ea...

NSW saw the largest earthquake last week: a magnitude 2.7 north of Lake Wyangala, along with a 2.2 near Cadia. Victoria had a little swarm near Kerang in the state's northwest, and a magnitude 2.5 tremor north of Moe, near the location of the magnitude 5.6 earthquake in June 2012.

Over a 5 day period, two earthquakes of magnitude 2.5 and one of magnitude 2.3 occurred near Cadia NSW. Another of magnitude 2.4 occurred near Tumbarumba in that state, and a magnitude 2.2 near the Qld border northeast of Mungindi rounds out the largest of the events from last week.

A magnitude 7 earthquake in Indonesia is rumbling across our network.

The largest of last week's 47 earthquakes was magnitude 3.2 that occurred north of Dubbo NSW. The state also hosted magnitudes 3.1 and 2.9 earthquakes minutes apart, occurring near the Qld border, south of Goondiwindi.

A little swarm of earthquakes occurred near the small network that we operate in Queensland. Over 30 earthquakes were detected in a 24 hour period last week.

A sparse week for earthquakes outside of SA - only 22 earthquakes detected in total. The largest was a magnitude 2.8 in NSW, located literally "Back O'Bourke". The other yellow dot is a magnitude 2.3 near Woods Point VIC, which still hasn't completely settled down almost 4 years after the big one.

Here’s another technical explainer video where I try to show how only 40% of the frequency of sampled seismic data represents the frequencies of the earth. Researching this helped me understand how alias frequencies masquerade in our data when they don’t actually exist, and why we need good filters.

Here’s the last 2 weeks of earthquakes in southeastern Australia. 103 in total: 9 in the M2 range, 51 in the M1 range, and 43 below M1. You can almost trace our mountain ranges with these plots, funnily enough.

A magnitude 2.7 earthquake occurred near Traralgon VIC at 7:35am this morning. Report it to Geoscience Australia if you felt it.

It’s all happening on our YouTube live stream tonight - a magnitude 2.4 earthquake at Dalton NSW followed a few minutes later by a 2.6 at Mt. Kosciuszko, just as energy waves from a magnitude 5.8 near Taiwan arrive in southeast Australia
