USGS posted the first photo to their instagram with this caption:

Denali Fault — This month is #preparedness month at USGS. We’ll be sharing information throughout the month related earthquakes, volcanoes, and other natural hazards as well as information about being informed and prepared for events like this. This photo, taken in November 2002, shows USGS’s Peter Haeussler preparing to measure the offset of a crevasse on the Canwell Glacier. On Nov 3, 2002 a M7.9 earthquake struck near Denali National Park in Alaska—the largest event on the Denali fault since 1912—and last 1-1/2 - 2 minutes. Although the Denali Fault shifted about 14 feet beneath the Trans-Alaska Oil Pipeline, the pipeline did not break, averting a major economic and environmental disaster. This was largely the result of stringent design specifications based on geologic studies done by the USGS and others 30 years earlier

I thought it looked cool so I looked for the original source. There are a bunch of other cool pictures (some of which I’ve seen before) and added my favorite here. A step in the fault shows the amount of horizontal offset.

can someone please explain cav empt to me

The name is short for “caveat emptor”, which is “buyer beware” in Latin. They are literally telling you to beware of buying their stuff, probably because it is so ridiculous. So the whole thing’s a joke and/or intentionally ironic. Not sure if people who buy it do so because they understand it’s a joke but I’m sure they see the irony.

historical-nonfiction:

Welcome to Derinkuyu, an underground city that once housed up to 20,000 people. In the Cappadocia region, famous for its cave dwellings and underground villages, Derinkuyu stands out for sheer size and complexity. Locals began digging in the 500s BCE. The city consists of over 600 doors, each of which can be closed from the inside. Each floor could be closed off as well. And just to make attacking completely impossible, the entire city was deliberately built without any logic. Its maze-like layout makes navigating the city nightmarish for unfamiliar invaders.
