Two faults of the East Anatolian Fault (EAF) system ruptured today. First, a Mw7.8 #earthquake on EAF main strand probably breaking several segments. Second a Mw7.5 to 7.7 on the Sürgü-Çartak Fault (EAF N strand). Both ruptures are outlined by their aftershocks (circles on map), and both are left-lateral.

There are many aftershocks following the two big earthquakes, but the second rupture is rather a triggered earthquake on an adjacent fault belonging to the EAF system.

This reminds us to be wary of possible strong aftershocks or triggered ruptures in the following days-weeks after a big earthquake.

@coldhotman Sorry. No time to answer now. Too many journalists…

Strong destructive #earthquake in SE Turkey / N Syria, magnitude Mw~7.8.

Mechanism compatible with left-lateral strike-slip on the southern part of East Anatolian Fault system. Aftershock zone extends for ~250km along that fault system. Complex source time function may suggest rupture on several fault branches. The left-lateral East Anatolian Fault system bounds the Anatolian tectonic microplate to the east.

The prompt and the text written by #openai #GPT-3:

Prompt: Write a text explaining: why the discovery of the West Andean Thrust is important; why the fact that the Andes primarily formed by west directed faulting changes our understanding of orogeny linked to subduction; what is the role of the San Ramon Fault in these processes and the implications on earthquake hazard.

Answer:

The discovery of the West Andean Thrust is important because it provides evidence that the Andes primarily formed by west directed faulting. This changes our understanding of orogeny linked to subduction, as it shows that the Andes were not created solely through east-directed thrusting from subduction zones. Instead, this west-directed faulting has been found to be a major contributor to the formation and uplift of the Andes.

The San Ramon Fault plays an important role in these processes, as it is one of the main faults responsible for west-directed faulting in the region. It is believed that this fault was active during periods of mountain building, which allowed for increased uplift and deformation in the region. Furthermore, its activity has implications on earthquake hazard in the area, as earthquakes originating from this fault can cause significant damage due to its proximity to populated areas.

Overall, the discovery of the West Andean Thrust and its associated west-directed faulting contributes greatly to our understanding of orogeny linked to subduction and provides insight into how mountains form. The San Ramon Fault also plays an important role in these processes and has implications on earthquake hazard in nearby areas.

I asked #openai #GPT-3 #AI #LLM to write something about the #orogeny in the #Andes.

Well written, but verbose and without much meaning. It basically repeats the prompt's ideas introducing some new details. However it's not enough to say that something is important, you have to explain why. A student giving such an answer will get a bad mark.

I'm not surprised as there is no intention, no understanding by the AI. But such a text can impress / convince a naive person on the subject, and even perhaps even some decision-makers and managers of science.

Speaking in Davos, the UN secretary general, António Guterres, accused big oil companies of peddling 'the big lie', calling for them to be held accountable.

“Today fossil fuel producers and their enablers are still racing to expand production knowing full well that this business model is inconsistent with human survival”

Magnitude Mw~7 #earthquake north of #Halmahera (#Maluku island, Indonesia) in a complex tectonic setting where several micro-plates interact. Quite large discrepancy btw depth estimates (16-46km), complicated source time function. Mechanism is mainly strike-slip.
