Great to hear that the revised magnitude for last Sunday's earthquake agrees with the SRC's initial assessment. Australia's low attenuation of ground motion allows magnitude 4 earthquakes to be felt over 600km away🤯
After manual analysis, Sunday night's earthquake in
#Melbourne
has been upgraded to magnitude 4. We also detected a 2.6 magnitude aftershock two minutes later. There are now 26,672 felt reports from northern Victoria to Tasmania. For more:

We’ve had a report of someone in a tall narrow building in Queensland feeling the Victorian earthquake. Energy waves at this distance would be very low frequency. Tall buildings can resonate at low frequencies and amplify ground motion, so this is definitely possible.

We've added a new colour to the map for this week! The Mw5.9 earthquake is black, with a multitude of M1+ events hiding the M4.2, five M3+, and 27x M2+ aftershocks. Around 180 of the week's 208 events were part of the Woods Point earthquake sequence. This week needs a thread👇

A swarm of 17 earthquakes occurred southeast of Anglesea VIC last week, measuring between magnitude 0.8 and 1.7. The magnitude 2.2 earthquake north of Mansfield VIC was felt. The largest event of the week was a magnitude 2.5 earthquake located about 60km northeast of Tamworth NSW

The big news last week was a magnitude 3.1 earthquake followed 2 days later by a magnitude 4.3 around 10km to the west. The latter was near Leongatha VIC and was felt across Melbourne. This was the largest earthquake in the Gippsland region since June 2023 (M4.7 near Woods Point)

A magnitude 2.9 earthquake this morning near Mount Howitt VIC was the largest in the last week. The smallest we detected was a magnitude -0.1. How, you may ask?
Magnitudes are mathematical exponents. A magnitude 0.0 is 10x smaller than a 1.0, and a -0.1 is ~20% smaller than a 0.0

Seismologists, do you hate it when your MiniSEED viewer shows you a great waveform, but displays the amplitude in counts and you want to see ground motion? Now you can use our Waves software, which automatically grabs meta data from

for registered stations. Free & easy!

In most countries a magnitude 2.5 earthquake wouldn’t warrant attention, but in Australia earthquakes tend to be closer to the surface and energy waves travel further due to rock density. Also, we don’t feel earthquakes as often here, so they freak us out more when we do.

In 2023 our Duty Seismologists had to send a total of 158 notifications to 22 different authorities for dozens of earthquakes ranging in magnitude from 1.9 to 5.1.

This magnitude 3.0 earthquake that occurred at 5:13am is about 20km to the northwest of the ongoing Woods Point aftershocks, so is likely to be on a different local fault that has been activated by the recent shaking.
