Ooh, great writeup on the Aegean Sea and some background on the geology of the region.

Here's a fresh #introduction for the new to me server.
Most know me as Tim N7KOM aka N7KOM Mountaintop Portable Radio on YouTube. Got my ham license in 2020. I mostly operate #SummitsOnTheAir #SOTA and #qrp.
I used to study #geology, #faults, and #earthquakes. I don't anymore, but I try to stay curious about our world.

El Centro in the Bradley #seismic zone is experiencing an #earthquake #swarm. I have plotted today’s events with a green outline in a map that I made when the previous swarm happened (blue outline) in April of 2023. The biggest quake in this sequence is a M4.8 & the swarm may already be dying down.

Ojai is all faults, but the giant probably-fault-scarp (?) that is Sulphur Mountain is not marked as a fault. I am starting to think these earthquake fault maps are based on accessibility via ground. #earthquake #faults #Ojai

Hmm... if you live in Santa Barbara, it appears you live closer to an earthquake fault than a bus line. #earthquake #faults #SantaBarbara

While #earthquakes are not new to the Pacific Northwest, the study identified that events on these shallow #faults are linked to each other in some way, either by connections underground or by one fault transferring stress to the other.

The M6.9 #earthquake in #Morocco occurred in a region with mapped #faults, but with relatively low historical #seismicity. Current reports indicate at least 600 people have been killed in this event and the city of Marrakesh has been badly damaged.

"#Colonizers kill, #displace, #ignore, #traumatize, #exploit and #oppress the #indigenous #people who have taken care of the #land they lived on for THOUSANDS of years, and then when they see the land degrading around them have the fucking GALL to have all their #environmental messaging be like "Wahh #humans bad and #evil and #greedy :("
Like no you dumb motherfuckers you just uprooted the people who knew what they were doing, and when stuff starts to go to shit you decide it must be that humans are inherently awful because it's easier than admitting that YOU LOT fucked up."
"Its a reflection of how they consider themselves the #protagonists of #history and therefore everything about their #culture is normal and all their #faults are #universal. Its also trying to obscure the #responsibility of a particular #economic #system which very powerful people benefit from for the unprecedented #ecological #disaster we're hurtling into."

Strike-slip #faults, such as the San Andreas Fault in #California or the #Denali Fault in #Alaska, are among the most well-known and capable of seriously powerful #seismic activity.

I realized that I never posted an #introduction on mastodon. Seeing a lot of new and familiar faces join this week so I'll better late than never!
