A paper in the “Geochemistry, Geophysics, Geosystems” journal lays out the suffering the US would undergo in a worst-case scenario disaster, predicting most major cities in the US being covered in layers of potentially deadly volcanic ash. 2014

"1964 Quake: The Great Alaska Earthquake" is an eleven minute video highlighting the impacts and effects of America's largest recorded earthquake. It is an expanded version of the four minute video "Magnitude 9.2". Both were created as part of USGS activities acknowledging the fifty year anniversary of the quake on March 27, 2014. The video features USGS geologist George Plafker, who, in the 1960's, correctly interpreted the quake as a subduction zone event. This was a great leap forward in resolving key mechanisms of the developing theory of plate tectonics. Landslide impacts and the extreme tsunami threat posed by these quakes are also discussed. Loss of life and destruction from the earthquake and accompanying tsunamis was the impetus for things like the NOAA Tsunami Warning Centers and the USGS Earthquake Hazards Program.

120 Years of Earthquakes and Their Tsunamis: 1901-2020 This animation shows every recorded earthquake in sequence as they occurred from January 1, 1901, through December 31, 2020, at a rate of 1 year per second. More geography related videos here https://rumble.com/playlists/cYA64Dyo9DY

How Mountains Are Created - Geography Basics A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (980 ft) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction, such as mining and logging, along with recreation, such as mountain climbing and skiing. The highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m (29,035 ft) above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m (69,459 ft). More geography related videos here https://rumble.com/playlists/cYA64Dyo9DY
