The 5 Biggest Earthquakes in History
Earth Wind and Fire
The Alaskan earthquake
Also called Great Alaska Earthquake occurred on March 27, 1964 at 17:36 hours. Fortunately the quake of 9.2 Richter degrees occurred in the unpopulated state.
This great earthquake and tsunami took the lives of 128 people (113 tsunami, earthquake 15).
Earthquake in Sumatra, Indonesia
The December 26, 2004 an earthquake measuring 9.1 on the Richter scale was recorded at 6:58 hours.
The earthquake occurred when the tectonic plates of India and Burma made contact whose energy is said to be 23,000 times greater than that generated by the atomic bombing of Hiroshima. The balance of the earthquake and tsunami: 280 thousand victims.
The worst earthquake in Japan's history
The March 11, 2011, the Pacific plate moved west with respect to the North American plate, 130 kilometers east of the city of Sendai. The magnitude was 9 degrees on the Richter scale. The death toll was more than 20,000, more than 3000 missing and 6000 injured 25.
1952 Kamchatka earthquake
The main quake occurred at 16:58 GMT (4:58 local time) on November 4, 1952. The magnitude of 9.0 Mw. A tsunami caused great destruction and loss of life around the Kamchatka Peninsula and the Kuril Islands. Hawaii was also hit, with estimated damages of up to $ 1 million, but no human casualties reported. The tsunami reached as far away as Alaska, Chile and New Zealand

1964 Quake: The Great Alaska Earthquake
Earth Wind and Fire
"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.

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).
