This morning, a M4.6 (prelim.) earthquake near Singleton was felt across eastern NSW. Our latest analysis here at @earthquakes-au.bsky.social now has this as M4.9 with a depth of <4 km - comparable to the depths of earthquakes at the nearby Mt Arthur Coal Mine in 2024. www.abc.net.au/news/2025-04...

In the last ~2 weeks the Asia Pacific region experienced several significant earthquakes. In addition, Japan released casualty and economic loss scenarios in the event of a local M8.0+ earthquake. I answer a few questions in this Explainer @earthquakes-au.bsky.social www.abc.net.au/news/2025-04...

A spate of earthquakes just rattled the Asia Pacific. Should we worry?

The deadly Myanmar earthquake last week was the biggest among a number of smaller quakes that rocked the region.

The whole #MyanmarEarthquake rupture in one interferogram! This is three consecutive wide swath frames of ALOS-2 data, provided by JAXA through agreement with NASA. The line-of-sight (LOS) is ~perpendicular to fault strike, so most of what you see is vertical motion at bends and steps of the fault.

A M7.7 followed ~11 mins later by a M6.4 aftershock - still a strong earthquake and likely damaging in itself - in Myanmar/ Burma about 40 mins ago. It took ~12 minutes for the associated waveforms to arrive at our recorders in the @earthquakes-au.bsky.social network in southeast Australia.

When 4 becomes 3: textbook example of “soft first storey collapse” as the US embassy in Vanuatu loses its ground floor in yesterday’s M 7.3 earthquake. Luckily it appears staff were out for lunch (acc. to the Guardian). This is my worst fear whenever I enter an older multi-storey here in Cascadia

The formerly four storey US embassy in Vanuatu, with its ground floor pancaked flat from yesterday’s earthquake. It now looks like a three storey building.

A seismologist from @monashuniversity.bsky.social explains that more earthquakes could hit Vanuatu as rescue workers dig through rubble. The magnitude 7.2 quake that struck near Port Vila was just 50km below ground. This shallow depth made it especially damaging.

The Vanuatu M7.3-M7.5 earthquake is located directly under an island and caused significant damage. The mechanism shows a near vertical or horizontal fault plane. Calculated depths vary between 25-50 km. Given location & magnitude, it may have been generated by faulting within the subducting slab.🧪⚒️

🧪⚒️ I modeled earthquakes on the San Andreas and San Jacinto faults – constrained by historic and geologic records – to show they can collaborate on a big quake (and probably did in 1812). This has implications for hazard and for how faults share the CA plate boundary. www.science.org/doi/10.1126/...

science.org

A case for historic joint rupture of the San Andreas and San Jacinto faults

The San Andreas and San Jacinto faults likely slipped together in a single earthquake in 1812 and are capable of doing so again.
