1993 Klamath Falls Earthquakes
The 1993 Klamath Falls earthquakes took place in Klamath Falls, Oregon, beginning on Monday, 20 September at 8:28 p.m. The doublet earthquake registered respective magnitudes of 6.0 and 5.9 on the moment magnitude scale. The earthquakes were located at a depth of and tremors continued to be felt more than three months after the initial shocks. Tectonics and previous activity The tectonic structure of south-central Oregon is riddled with fault lines. The West Klamath Lake fault zone is capable of earthquakes up to Richter magnitude 7.3. The magnitude 5.4 Coos Bay earthquake which preceded a later 2002 Klamath Falls earthquake occurred along the northern segment of the Blanco Fracture Zone, which is separate from the inland Klamath Basin and Range geological province. These fault networks have caused several previous earthquakes in the Klamath Falls area. Records from 1945 indicate approximately fifteen seismic events, prior to the 1993 events, circulating within a radius ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doublet Earthquake
__NOTOC__ In seismology, doublet earthquakes – and more generally, multiplet earthquakes – were originally identified as multiple earthquakes with nearly identical waveforms originating from the same location. They are now characterized as single earthquakes having two (or more) main shocks of similar magnitude, sometimes occurring within tens of seconds, but sometimes separated by years. The similarity of magnitude – often within 0.4 magnitude – distinguishes multiplet events from aftershocks, which start at about 1.2 magnitude less than the parent shock ( Båth's law) and decrease in magnitude and frequency according to known laws. Doublet/multiplet events also have nearly identical seismic waveforms, as they come from the same rupture zone and stress field, whereas aftershocks, being peripheral to the main rupture, typically reflect more diverse circumstances of origin. Multiplet events overlap in their focal fields (rupture zones), which can be up 100 kilometers across ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural Disasters In Oregon
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-Soc ...

Community Development Block Grant
The Community Development Block Grant (CDBG), one of the longest-running programs of the U.S. Department of Housing and Urban Development, funds local community development activities with the stated goal of providing affordable housing, anti-poverty programs, and infrastructure development. CDBG, like other block grant programs, differ from categorical grants, made for specific purposes, in that they are subject to less federal oversight and are largely used at the discretion of the state and local governments and their subgrantees. History The CDBG program was enacted in 1974 by President Gerald Ford through the Housing and Community Development Act of 1974 and took effect in January 1975. Most directly, the law was a response to the Nixon administration's 1973 funding moratorium on many Department of Housing and Urban Development (HUD) programs. President Ford emphasized the bill's potential for reducing inefficient bureaucracy, as the grant replaced seven previous programs ...

Klamath County, Oregon
Klamath County ( ) is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 69,413. The county seat is Klamath Falls. The county was named for the Klamath, the tribe of Native Americans living in the area at the time the first European explorers entered the region. Klamath County comprises the Klamath Falls, OR Micropolitan Statistical Area. History The Klamath or ''Clamitte'' tribe of Indians, for which Klamath County was named, are the descendants of varying cultures of indigenous peoples, who have lived in the area for more than 10,000 years. When European-Americans began to travel through the area in 1846 along the Applegate Trail, they competed with the Klamath for game and water, which precipitated clashes between the peoples. This was exacerbated by European-American settlers, who cleared the land to farm and encroached on hunting territory. They were successful in demanding the removal of American Indians to reservations. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Slide
A rockslide is a type of landslide caused by rock failure in which part of the bedding plane of failure passes through compacted rock and material collapses ''en masse'' and not in individual blocks. Note that a rockslide is similar to an avalanche because they are both slides of debris that can bury a piece of land. While a landslide occurs when loose dirt or sediment falls down a slope, a rockslide occurs only when solid rocks are transported down slope. The rocks tumble downhill, loosening other rocks on their way and smashing everything in their path. Fast-flowing rock slides or debris slides behave similarly to snow avalanches, and are often referred to as rock avalanches or debris avalanches. Definition The term landslide refers to a variety of mass wasting events (geologic slope failures) that include slumps, slides, falls, and flows. The two major types of slides are rotational slides and translational slides. Rockslides are a type of translational event since the rock ...
