2018 Southern Appalachian Earthquake
An earthquake measuring 4.4 MW on the moment magnitude scale struck north-northeast of Decatur, Tennessee in the eastern part of the state on December 12, 2018 at 4:14 a.m. Eastern Standard Time. The earthquake occurred at a depth of . The earthquake occurred along the Eastern Tennessee Seismic Zone (ETSZ), a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes. The earthquake was felt throughout the Southeast, primarily in eastern Tennessee and the Atlanta metropolitan area. While relatively minor, this earthquake was the largest to occur on the ETSZ since the 4.6 MW 2003 Alabama earthquake, the third largest to have been recorded in the area, becoming the fourth largest earthquake recorded in the region. Robert Sanders from the U.S. Geological Survey told WSB-TV that aftershocks would be possible throughout the day after the quake. Geologic background The ETSZ is one of the most seismically active area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Time Zone
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama, Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands. Places that use: * Eastern Standard Time (EST), when observing standard time (autumn/winter), are five hours behind Coordinated Universal Time ( UTC−05:00). * Eastern Daylight Time (EDT), when observing daylight saving time (spring/summer), are four hours behind Coordinated Universal Time ( UTC−04:00). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour "gap". On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Coast Of The United States
The West Coast of the United States, also known as the Pacific Coast, Pacific states, and the western seaboard, is the coastline along which the Western United States meets the North Pacific Ocean. The term typically refers to the contiguous U.S. states of California, Oregon, and Washington, but sometimes includes Alaska and Hawaii, especially by the United States Census Bureau as a U.S. geographic division. Definition There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California, Oregon, and Washington as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska, as they are all located in North America. For census purposes, Hawaii is part of the West Coast, along with the other four states. ''Encyclopædia Britannica'' refers to the North American region as part of the Pacific Coast, including Alaska and British Columbia. Although the enc ...

Natural Disasters In Tennessee
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-So ...

2018 Earthquakes
This is a list of earthquakes in 2018. Only earthquakes of magnitude 6 or above are included, unless they result in damage and/or casualties, or are notable for other reasons. All dates are listed according to UTC time. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. In a busy year with 17 major quakes, Indonesia was hit particularly hard. More than 500 people died in Lombok in August and a major earthquake struck the Palu region in September, with more than 4,000 casualties caused mainly by liquefaction and a tsunami. Other deadly events took place in Papua New Guinea, Japan, Haiti, Taiwan and Mexico. The strongest quake with a magnitude of 8.2 occurred in Fiji, at a great depth of . Compared to other years An increase in detected earthquake numbers does not necessarily represent an increase in earthquakes ''per se''.
