2008 Illinois Earthquake
The 2008 Illinois earthquake was one of the largest earthquakes ever recorded in the Midwest state of Illinois. This moderate strike-slip shock measured 5.2 on the moment magnitude scale and had a maximum Mercalli intensity of VII ''(Very strong)''. It occurred at on April 18 near Bellmont and Mount Carmel, Illinois, within the Wabash Valley Seismic Zone. Earthquakes in this part of the country are often felt at great distances. Tectonic setting Situated in a stable continental region of the Midwestern United States, the Wabash Valley Seismic Zone (WVSZ) is an area of dispersed seismic activity that encompasses the border areas of Illinois, Indiana, and Kentucky. This broad, multistate zone of intraplate seismicity lay just to the north of the New Madrid Seismic Zone and comprises both strike-slip and dip-slip earthquake mechanisms across numerous named faults, grabens, and anticlines.

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louisville, Kentucky
Louisville ( , , ) is the largest city in the Commonwealth of Kentucky and the 28th most-populous city in the United States. Louisville is the historical seat and, since 2003, the nominal seat of Jefferson County, on the Indiana border. Named after King Louis XVI of France, Louisville was founded in 1778 by George Rogers Clark, making it one of the oldest cities west of the Appalachians. With nearby Falls of the Ohio as the only major obstruction to river traffic between the upper Ohio River and the Gulf of Mexico, the settlement first grew as a portage site. It was the founding city of the Louisville and Nashville Railroad, which grew into a system across 13 states. Today, the city is known as the home of boxer Muhammad Ali, the Kentucky Derby, Kentucky Fried Chicken, the University of Louisville and its Cardinals, Louisville Slugger baseball bats, and three of Kentucky's six ''Fortune'' 500 companies: Humana, Kindred Healthcare, and Yum! Brands. Muhamm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Princeton, Indiana
Princeton is the largest city in and the county seat of Patoka Township, Gibson County, Indiana, United States. The population was 8,301 at the 2020 United States Census, and it is part of the greater Evansville, Indiana, Metropolitan Area. History In 1800, the Indiana Territory was created with Vincennes (Knox County) as its capital. The rich farmlands in the southwest of the territory with access to the Ohio River attracted many pioneers and settlers to the area, one of whom was an Irish immigrant named William Prince. Born in 1772, he immigrated to America at the age of 22. He later became a Gibson County Commissioner and the county seat of Princeton is named after him. The year 1813 saw the move of the territorial capital east from Vincennes to Corydon and the creation of Gibson County. Gibson had previously been part of the vast Knox County which covered all the land of southwestern Indiana, bordered by the Wabash and Ohio Rivers. By early 1814, settlers to this area we ...

Edwards County, Illinois
Edwards County is a county located in the U.S. state of Illinois. As of the 2010 census, the population was 6,721. Its county seat is Albion. History Edwards County was named for Ninian Edwards, the governor of the Illinois Territory, and, later, governor of Illinois. Edwards County is subdivided into "Road Districts", rather than "Townships" as in most Illinois counties. Pursuant to the Land Ordinance of 1785, the Northwest Territory (including Illinois) was surveyed and mostly organized into townships that are six miles square; but Edwards County was settled prior to that survey, and its pre-existing Road Districts do not generally correspond with the survey's townships.

Seismic Wave
A seismic wave is a wave of acoustic energy that travels through the Earth. It can result from an earthquake, volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low-frequency acoustic energy. Seismic waves are studied by seismologists, who record the waves using seismometers, hydrophones (in water), or accelerometers. Seismic waves are distinguished from seismic noise (ambient vibration), which is persistent low-amplitude vibration arising from a variety of natural and anthropogenic sources. The propagation velocity of a seismic wave depends on density and elasticity of the medium as well as the type of wave. Velocity tends to increase with depth through Earth's crust and mantle, but drops sharply going from the mantle to Earth's outer core. Earthquakes create distinct types of waves with different velocities. When recorded by a seismic observatory, their different travel times help scientists locate the quake's hypocen ...

Upper Peninsula Of Michigan
The Upper Peninsula of Michigan – also known as Upper Michigan or colloquially the U.P. – is the northern and more elevated of the two major landmasses that make up the U.S. state of Michigan; it is separated from the Lower Peninsula by the Straits of Mackinac. It is bounded primarily by Lake Superior to the north, separated from the Canadian province of Ontario at the east end by the St. Marys River, and flanked by Lake Huron and Lake Michigan along much of its south. Although the peninsula extends as a geographic feature into the state of Wisconsin, the state boundary follows the Montreal and Menominee rivers and a line connecting them. First inhabited by Algonquian-speaking native American tribes, the area was explored by French colonists, then occupied by British forces, before being ceded to the newly established United States in the late 18th century. After being assigned to various territorial jurisdictions, it was granted to the newly formed state of Michigan as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
