During the STS-68 mission (September 30-October 11, 1994), the crewmembers of Space Shuttle Endeavour used a 70 mm camera to photograph Klyuchevskaya Sopka (also known as Kliuchevskoi), a stratovolcano, the highest mountain on the Kamchatka Peninsula of Russia and the highest active volcano of Eurasia. The eruption was new when this photo was taken. It was photographed from 115 nautical miles (213 kilometers) above Earth.

I stumbled upon an amazing web page showing what did ancient Earth look like. On “Dinosaur Pictures and Facts” web page (dinosaurpictures.org), there’s also an interactive animation. On this page, you can either select the years (i.e. 600 million years ago) or jump to a particular event (i.e. first multicellular life) and see how ancient Earth did look like then. You can also remove the clouds and stop the Earth’s rotation if you want to.

Earth’s outer shell is divided into multiple plates that slowly glide over the mantle. The movement of these plates slowly changes Earth’s surface over time by merging, or separating, continents. 250 million years from now, consistent with the supercontinent cycleNotes 1, there will be a possible future supercontinent called Pangaea Ultima. Hypothesized by Christopher Scotese, a geologist at the University of Texas at Arlington, Pangaea Ultima earned its name from its similarity to the previous Pangaea supercontinent, which was formed about 335 million years ago, and began to break apart about 175 million years ago. Here is a beautiful video published by the Tech Insider channel showing the formation of this supercontinent.

In December 2014, an underwater volcano has made a new island with a 120-meter (400-foot) summit in the South Pacific, between two older islands (Hunga Tonga and Hunga Ha’apai) in the kingdom of Tonga. NASA satellites captured the amazing process.

On May 12, 2008, a huge 7.9 MW earthquake hit Chengdu, a sub-provincial city which has served as capital of China’s Sichuan province. Over 69,000 people lost their lives. 374,176 were reported injured, with 18,222 listed as missing as of July 2008. The earthquake also left about 4.8 million people homeless. Some scientists believe that the construction and filling of the Zipingpu Dam with 320 million tons of water over a well-known fault line may have triggered the earthquakeNotes 1.

The American scientific agency within the United States Department of Commerce, National Oceanic and Atmospheric Administration (NOAA) published an animation on youtube showing the Earthquakes of the First 15 Years of the 21st Century (between January 1, 2001 and December 31, 2015). The animation shows every recorded earthquake in sequence as they occurred at a rate of 30 days per second. It is based on the new SOS dataset of all the earthquakes in that period from the US NWS Pacific Tsunami Warning Center.
