🌟 OPEN ACCESS 🌟 Scientists studying a newly published, high-resolution earthquake catalog for Nevada found that dynamic triggering can provide valuable insight into identifying critically stressed regions. #BSSA ⚒️ buff.ly/Lin6X8Q
The left panel shows teleseismic earthquakes (greater than or equal to magnitude 7.0) from January 1, 2008 to December 31, 2023 are represented by circles. The size of each circle corresponds to earthquake magnitude, whereas the fill color indicates the earthquake’s depth range. The study area in Nevada is highlighted by the green square, and the asterisks mark the nine teleseismic triggering events. The right panel shows local earthquakes (less than or equal to magnitude 5.0) in the study area that occurred within the same duration of teleseismic event mapped in left panel.

🚨 Publication Alert! A new open-access paper from the World Stress Map team uses data from 12 boreholes to characterise the stress state of Australia’s Beetaloo Sub-basin, highlighting the key role of lithology in local stress variability. Download Link: doi.org/10.1016/j.jr... #Geomechanics

Excited to share a new open-access paper by Oliver Heidbach and Mojtaba Rajabi @geostress.bsky.social, marking the 40th anniversary of WSM project. Using 100,842 stress records, the study provides fresh insights into present-day global tectonic stresses. Download link: doi.org/10.5194/se-1...

For those who are curious about the #qld earthquake on Saturday morning here is an article in the @aunz.theconversation.com written by @deeninis.bsky.social and @mojtabarajabi.bsky.social - why does Australia get earthquakes when it isn’t close to any plate boundaries? Read to find out more.

Why does Australia have earthquakes? The whole continent is under stress from distant forces
Australia is a long way from the tectonic plate boundaries where most earthquakes happen – but we can’t escape the forces they create.

Why does tectonically “stable” Australia get earthquakes? @deeninis.bsky.social, Abbas and I explain in our new article for The Conversation. theconversation.com/why-does-aus...

Felt the quake here in Brisbane! At 9:49am, a magnitude ~5 earthquake (GA 5.6 ML; GFZ: 5.4; 4.9 USGS) occurred ~160km from Brisbane. Despite QLD’s relatively low seismicity compared to other parts of Australia, the tremor was felt across a wide area. details below from GA.

World 🌏stress map 4th edition. 100000 data points from across the world. New australian borehole data shiw that sometimes local orocesses 🪨 more important than large scale plate tectonics. Large international collaboration including work by Dr Rajabi at UQ. Database available, Paper in review.

Abstract. The impact of faults on the contemporary stress field in the upper crust has been discussed in various studies. Data and models clearly show that there is an effect, but so far, a systematic...

I did this photo in October 2022, in Millook Haven (Cornwall, UK). I may not be my best geological photo, but it's the one that pleases me the most. ⚒️🧪
