"Anchor Bolts" by XKCD comic (mirror bots @xkcd @xkcdbot ) - If they were to do this in the Pacific Northwest #PNW to hold in place the Cascadia Subduction Zone, these giant bolts would be installed inland at intervals near Medford, Eugene, Portland, Olympia, Seattle, Burlington and Vancouver. Keep them away from the Cascade volcano magma chambers which would loosen the grip of the bolts. https://xkcd.com/3078/ #geology #mapgeek #humor #WTF

transcript & explanation (truncated to fit) from ExplainXKCD https://www.explainxkcd.com/wiki/index.php/3078:_Anchor_Bolts
transcript:
[Panel shows Randall's usual illustration of a subduction zone: a tectonic plate subducting from the left side of the panel with water above it, and a mountain range forming on the right side of the panel on the other tectonic plate. Beneath each tectonic plate is the asthenosphere. The main difference between this image and others like it is that there is a bolt shown attaching the plates together in the subduction zone. The head of the bolt is shown in the asthenosphere below the subducting plate. There are two washers displayed, one between the bolt head and the subducting plate and one above the other above the upper plate on the side of a smaller mountain. A wing nut is positioned above this washer, with part of the bolt sticking out above the nut, higher than the tallest mountains in the panel]
[Caption below the panel:]
Good news: Geophysicists are finally installing Earth's required anti-subduction anchor bolts.
explanation:
The comic displays a cross-section of a subduction zone, with an anchor bolt connecting the two tectonic plates. Anchor bolts are used to secure an item in place, for instance to attach a building to it's foundation. In earthquake prone areas, anchor bolts are often used to secure furniture so it will be less hazardous during a tremor.

@elaterite @User47 Right down the road... 
Yeah, they're both on US 93. 267mi apart.

For any #avgeek who wants to review the route #PhilippineMars WWII flying boat took on its last flight from Alameda CA to Lake Pleasant AZ, I entered into SkyVector an approximate route from the C-FLYK and N2871G tracking. Waypoints were just to estimate the spot on the map - I have no info on the crew's intended route since no flight plan was made public. It seemed they followed a combination of coastline, roads and airways. https://skyvector.com/?ll=36.584657605422414,-118.94787597280629&chart=301&zoom=9&fpl=ILATE%203751N12221W%203749N12228W%203746N12232W%203740N12231W%203712N12224W%20KOAR%20TROXX%20AVE%20GRAPE%2050CN%20XBBOX%20BUGBE%20KBNG%20AKIPE%20TRRSH%20FOILD%20DINBE%20MACIS%20TANKZ%203354N11238W%203351N11217W%203353N11217W #aviation #avgeek #pilot #mapgeek #history
Online friends finally meet in person... I've known @Leighton for years from JetCityStar's biweekly Aerospace Chat. He's a fellow #avgeek, #spacegeek, #mapgeek, pilot and flight instructor. Now he's showing me around #Sydney. #Australia #travel
"All maps are wrong" by Here & There, Kyle Frost - Neither #maps nor #GPS positioning are as precise as people often expect. Even with a good #navigation receiver, a track from a hike or ride has errors around the actual path taken. https://www.hereandthere.club/post/all-maps-are-wrong #mapgeek #GNSS #tech
It would be so awesome to have a map nerd in the White House: “Walz tends to speak rapturously about the power of good maps to bring about social change. ‘I know I’m preaching to the choir, but the choir needs to sing,’ he told ESRI in 2024. ‘This stuff works. This stuff makes a difference. The map is wonderful to look at. It’s exciting.’”

"Is map-reading a lost art? In an era of #GPS, here's what map fans say we're losing" by @CBC - We use maps more than ever in digital society. But reading paper maps is a declining skill. It remains useful + backup for power failure. https://www.cbc.ca/news/canada/maps-cartography-skill-1.6871726 #MapGeek h/t @geoviews
"Our Maps Don’t Know Where You Are" by @themarkup - It's a rare good example of maps that respect your #privacy, displaying what was requested without trying to locate, identify and track you https://themarkup.org/hello-world/2023/05/27/our-maps-dont-know-where-you-are #mapgeek
Best Dad's joke ever for #mapgeek : Geology rocks, but Geography is where it's at!
