Sedimentologika is officially open for submission - #DOAJ Diamond Open Access Journal #openscience #openaccess
Hi! I’m a research scientist at the Geological Survey of Canada and adjunct professor at the University of British Columbia and the University of Victoria. I study #earthquakes and focus mostly on #SeismicRisk and #ActiveTectonics. I’m interested in #Paleoseismology #Neotectonics #Seismology #Geodesy and #SeismicHazard.
I’m also chair of the #AGU Hazards Equity Working Group, a Fast Reports editor at @weareseismica and a Building Equity & Capacity committee member for #SZ4D.

A magnitude Mw6.9 #earthquake offshore south-central #Sumatra.
Mechanism and location suggest rupture on the shallow part of the #subduction #megathrust close to the trench (on the very shallow dipping fault plane). However, modelled depth of ~19km, if true, seems little too deep given the closeness with the trench (USGS gives same depth and mechanism). This means that we cannot exclude a rupture on the steep fault plane within the oceanic plate.

Three other mysterious sketches. Now you know these are geographic maps to be completed. What are they showing ? 3/4
Answer tomorrow 😉
Yesterday I posted the sketch to the right asking "what is this?" Now you have the answer 👇🏼
It's from a 56 years old French book of #cartography exercises, to learn #geography at primary school. Now an amazing #sciart. 1/4
So this is my first post on Mastodon.
Part of my work as a volcanologist with the Italian National Institute of Geophysics and Volcanology (Istituto Nazionale di Geofisica e Vulcanologia, INGV) is the real-time surveillance of seismic and volcanic activity in the volcanic areas of Sicily. This is done in 8-hour shifts in the Operations Room of the INGV seat in Catania, the Osservatorio Etneo. This is me making a stupid face during my latest shift, on 5 November 2022.
A Kafkaian bird story RT:
Is there a #geotwitter equivalent here? For example, is it #geomastodon I wonder?
Well, well, happy to be there !

Being editor of Tektonika (https://tektonika.online) I'm so happy to see that our friends from Seismica @weareseismica have just published their editorial paper "The launch of Seismica: a seismic shift in publishing" 👏

@jascha Induced seismicity is much less trendy in the #insurance industry than it was back when it was happening right under Oklahoma City.
But for those who don't have USGS #earthquake alerts set to M3.5... there are still a ton of induced earthquakes! Now mostly in West Texas.

Dear #geotweeps,
We are very happy to announce that http://sedimentologika.org is online 🥳 you can check submission guidelines, reviewer guidelines and learn about the journal
Also submissions will be open starting 19th November 2022 🥳🎉 so get those manuscripts ready
RT @CopernicusEU: #DYK that parts of the Greek islands 🇬🇷 move (horizontally↔️) at a velocity of several mm per year?
You can monitor this phenomenon with the products of the @CopernicusLand European Ground Motion Service #EGMS
🆕The data can now be downloaded! More at https://land.copernicus.eu/news/the-european-ground-motion-service-archive-is-now-available
