  • So tsunamis are definitely a threat generally from earthquakes and an earthquake of this size can make it deadly. Unlike the San Andres faults that cause most California earthquakes ( which wouldn’t produce significant tsunamis) this earthquake occurred in a discordant part of the pacific oceanic crust called the Mendocino triple junction - the intersection of the San Andres fault, Cascadian subduction zone (where the Pacific crust is plunging under the North American continent, feeding features like Mt. St Helens), and the Gorda plate (the last remnant of the precursor to the pacific plate, the Panthalassic Ocean that surrounded Pangea).





  • A good point. From the get-go humans have been intensely tribal and fearful of outsiders. 10,000 years of history shows we kinda bumbled our way through it with a lot of causalities but also a lot of beautiful culture, art, feats, and athletic talent sprinkled in for people who had the time. Now every part of the earth is so interconnected it is unprecedented. How we bumble through this stage is unfolding into a sad story but I can’t get too beat up about it for my own sanity.

    There is a Potawotani word “puhpowee”, whose translation into English is “the force which causes mushrooms to push up from the earth overnight.” Puhpowee is the unseen, animating force that inhabits the natural world, the hot breath of life.




  • I am a geologist that works in the field of characterizing reservoirs for CCS projects. The way I see it, some fossil-fuel industries are here to stay and the best we can do is mitigate their emissions into the atmosphere. Take the UK, they got rid of their coal plants after 100 years and replaced it mainly with natural gas-burning plants, that energy portfolio is not changing to, say, wind or solar anytime soon but now the government (both parties too) are heavily investing in connecting those plants to CO2 storage in the bedrock of the North Sea (which has been demonstrated to be safe).

    Industrializing industries in Africa are also starting to construct new fossil fuel plants with CCUS technology. Fossil fuel burning is inherent to developing countries and at least technology can make the industrialization less dirty.

    Sorry I’m on mobile and would provide some sources. I can add them if you’re interested.




  • I worked in geotech consulting and there is one piece of radioactive equipment used for soil testing that requires a certification to operate and transport in a vehicle, called a nuclear density/moisture gauge. Every year there’s an article that makes the news where a technician forgets to strap down the equipment so it doesn’t fall out the truck or not locking the box that holds the equipment and someone steals it. People really are stupid and lots of companies that give out work trucks don’t teach employees basic safety especially when towing or transporting fragile things.


  • Having lived in Arizona for a few years and worked in the renewable energy industry there, I always found it surprising no long term planning on anyone’s part is done when designing a water-intensive project especially in the big cities. The problem is that water will still always flow through Phoenix, whether it’s the Colorado River or even more canal projects from other states, and rural folks will always drill deeper for water. It’s not a problem that there isn’t water it’s just the accessibility of the groundwater and how saline it is. The previous governor, Ducey, even suggested the state invest in desalination tech. The surface manifestations (ie earth fissures) of GW withdrawal are obvious but humans find a way to engineer around it or in some cases of Arizona desert they just don’t build there.

    Where I went to university the geography faculty were part of the Earth Science department. It formed a really interdisciplinary department, there was work being done, for example, in “health geography” — applying population & ecological studies, community health research, and epidemiology to understand disparities. Urban geography like was mentioned strives to understand of the role of cities in regional, national, and international developments but also how cities operate through governance and administration, the role of philanthropic institutions and NGOs, gentrification etc.
