Sedimentary basin. Cenozoic sedimentary basins in the U.S.
(from USGS) Methods of formation[edit] Sedimentary basins form primarily in convergent, divergent and transform settings. Convergent boundaries create foreland basins through tectonic compression of oceanic and continental crust during lithospheric flexure. 21 Scary Statistics About The 2011 Japan Earthquake. A few scary & depressing facts about the 2011 Tōhoku earthquake and tsunami: The Earthquake Magnitude of the quake: 9.0 Energy released by the quake: 480 megatons (a magnitude 9.0 earthquake releases as much energy as 32,000 magnitude 6.0 earthquakes)
Tsunami Factfile: Learn about the tsunami that struck Japan in March 2011. By Beth Rowen and Catherine McNiff Tsunami in Japan Japan was hit by a 9.0 magnitude earthquake on March 11, 2011, that triggered a deadly 23-foot tsunami in the country's north.
The giant waves deluged cities and rural areas alike, sweeping away cars, homes, buildings, a train, and boats, leaving a path of death and devastation in its wake. Video footage showed cars racing away from surging waves. Japanese Earthquake 2011. What?

Plate Tectonics, Tectonic Plates Information. There are a few handfuls of major plates and dozens of smaller, or minor, plates.
Six of the majors are named for the continents embedded within them, such as the North American, African, and Antarctic plates. Though smaller in size, the minors are no less important when it comes to shaping the Earth. The tiny Juan de Fuca plate is largely responsible for the volcanoes that dot the Pacific Northwest of the United States.
Understanding the Christchurch earthquake: building damage. There are many puzzles as to why some of Christchurch’s buildings have survived the 6.3 earthquake of February 2011, and others have not.
However, a combination of observations plus document-searching does provide some answers. In terms of magnitude, this was just a moderate earthquake, but the local effects on Christchurch have been huge because of its proximity and shallowness. Even within Christchurch, location was of huge importance, but there is more to it than that. It seems that we do indeed have very stringent building codes in New Zealand.
Not only are the codes stringent, but they are enforced. 2011 Tōhoku earthquake and tsunami. The 2011 earthquake off the Pacific coast of Tōhoku (東北地方太平洋沖地震, Tōhoku-chihō Taiheiyō Oki Jishin) was a magnitude 9.0–9.1 (Mw) undersea megathrust earthquake off the coast of Japan that occurred at 14:46 JST (05:46 UTC) on Friday 11 March 2011,[4][9][10] with the epicentre approximately 70 kilometres (43 mi) east of the Oshika Peninsula of Tōhoku and the hypocenter at an underwater depth of approximately 29 km (18 mi).[4][11] The earthquake is often referred to in Japan as the Great East Japan Earthquake (東日本大震災, Higashi nihon daishinsai)[12][13][fn 1] and is also known as the 2011 Tōhoku earthquake,[28] and the 3.11 earthquake.
Early estimates placed insured losses from the earthquake alone at US$14.5 to $34.6 billion.[53] The Bank of Japan offered ¥15 trillion (US$183 billion) to the banking system on 14 March in an effort to normalize market conditions.[54] The World Bank's estimated economic cost was US$235 billion, making it the costliest natural disaster in history.[55][56] Science Highlights 2010 - UNAVCO Event Response - Mw=8.8 Chile Earthquake Feb. 27, 2010.

Ground Truth Trekking Blog » Largest Earthquakes since 1900. Understanding the Christchurch Earthquake of 22 Feb 2011: magnitude, location and impact. Last September, those of us who live in Christchurch experienced a 7.1 earthquake. Since then, we have referred to that as ‘the big one’, confident that we would never again experience anything similar. In that September quake, there were no lives lost, but there were many houses badly damaged and destroyed. Within days, most of us were able to get on with our lives, although scratch below the surface and it was immediately obvious that many people were still struggling with the upheaval to their lives.
It wasn’t a case of some people being tougher than others. Understanding the Christchurch earthquake: building damage. There are many puzzles as to why some of Christchurch’s buildings have survived the 6.3 earthquake of February 2011, and others have not.
