Old City Hall Historic District
The Old City Hall Historic District is located on a bluff at the north end of Tacoma's business district, overlooking Commencement Bay. The Old City Hall (Tacoma, Washington), Old City Hall and the Northern Pacific Office Building stabilize the northern boundary of the district and the Pantages Theater (Tacoma, Washington), Pantages Theatre/Jones Building just south of the district boundary, complements the Winthrop Hotel. All blocks are laid out so that major building entrances face the streets, which run north and south, and the buildings are constructed with common walls, which cover the entire depth of the block, deleting any need for alleys. Thus, with the exception of Pacific Avenue, where business fronts face each other, business fronts tend to be located on the east. The western exposures represent the back of the structures. From the bluff to Pacific Avenue the land is level, but Commerce and Broadway form terraces on the steep hillside. As a result, a facade which appe ...

Carbon River
The Carbon River is a river in the U.S. state of Washington. It flows about 30 miles (48 km) from its source, the Carbon Glacier on Mount Rainier, to join the Puyallup River at Orting. Charles Wilkes called the river the "Upthascap River", but after the discovery of coal along its banks in 1876 the river was renamed "Carbon". Course The source of the Carbon River is the Carbon Glacier on the north side of Mount Rainier in the Cascade Range. The river's upper reach is contained within Mount Rainier National Park. Some of the river's headwater tributary streams include Cataract Creek and Spukwush Creek. The Carbon River quickly enters a broad glacial valley in which it deposits thick layers of glacial sediment. This causes the river to meander and becomes braided. After flowing by Mother Mountain on the west and Chenuis Mountain on the east, the Carbon River reaches Ipsut Creek and the national park campground of Ipsut Creek. This was also the end of the Carbon River Road ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Puyallup River
The Puyallup River ( ) is a river in the U.S. state of Washington. About long, it is formed by glaciers on the west side of Mount Rainier. It flows generally northwest, emptying into Commencement Bay, part of Puget Sound. The river and its tributaries drain an area of about in Pierce County and southern King County. The lower, northwestern half of the river's watershed is a complex amalgam of glacial and tectonic features dating back to the Pleistocene, as well as more recent (Holocene) changes caused by a series of lahars which flowed down from Mount Rainier between 5,600 and 800 years Before Present. The valley's 150,000 residents are at risk from future lahars. For this reason, the United States Geological Survey has installed a lahar warning system. Course The upper watershed of the Puyallup River flows off of Mount Rainier through the South Cascade Range of Washington towards the lowlands surrounding Puget Sound. The Puyallup River begins from two forks, the North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Rainier Volcano Lahar Warning System
The Mount Rainier Volcano Lahar Warning System consists of two separate components, operating in tandem: Acoustic Flow Monitors (AFM) and the All Hazard Alert Broadcast (AHAB) sirens. The AFM system was developed by the United States Geological Survey (USGS) in 1998 and is now maintained by Pierce County Emergency Management. The purpose of the warning system is to assist in the evacuation of residents in the river valleys around Mount Rainier, a volcano in Washington, in the event of a lahar. Pierce County works in partnership with the USGS, the Pacific Northwest Seismic Network (PNSN), Washington Military Department's Emergency Management Division, and South Sound 9-1-1 to monitor and operate the system. History Mount Rainier is an active volcano in Washington. It has previously buried sections of the surrounding river valleys in a volcanic mudflow, called a lahar. The Puyallup River Valley is at greatest risk. Tens of thousands of people live in areas that may have as little ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyroclastic Flow
A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of but is capable of reaching speeds up to . The gases and tephra can reach temperatures of about . Pyroclastic flows are the deadliest of all volcanic hazards and are produced as a result of certain explosive eruptions; they normally touch the ground and hurtle downhill or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope. Origin of term The word ''pyroclast'' is derived from the Greek (''pýr''), meaning "fire", and (''klastós''), meaning "broken in pieces". A name for pyroclastic flows that glow red in the dark is (French, "burning cloud"); this was notably used to describe the disastrous 1902 eruption of Mount Pelée on Martinique, a Frenc ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fracture in the Crust (geology), crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. Etymology The word ''lava'' comes from Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lahar
A lahar (, from ) is a violent type of mudflow or debris flow composed of a slurry of Pyroclastic rock, pyroclastic material, rocky debris and water. The material flows down from a volcano, typically along a valley, river valley. Lahars are often extremely destructive and deadly; they can flow tens of metres per second, they have been known to be up to deep, and large flows tend to destroy any structures in their path. Notable lahars include those at Mount Pinatubo in the Philippines and Nevado del Ruiz in Colombia, the latter of which killed more than 20,000 people in the Armero tragedy. Etymology The word ''lahar'' is of Javanese language, Javanese origin. Berend George Escher introduced it as a geological term in 1922. Description The word ''lahar'' is a general term for a flowing mixture of water and pyroclastic debris. It does not refer to a particular rheology or sediment concentration. Lahars can occur as normal stream flows (sediment concentration of less than 30%), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puyallup, Washington
Puyallup ( ) is a city in Pierce County, Washington, United States. It is on the Puyallup River about southeast of Tacoma and south of Seattle. The city had a population of 42,973 at the 2020 census. The city's name comes from the Puyallup tribe of Native Americans and means "the generous people" in Lushootseed. Puyallup is home to the Washington State Fair, the state's largest annual fair. The name of the city is also used in mailing addresses for adjacent unincorporated areas, such as the larger-populated South Hill. History The Puyallup Valley was originally inhabited by the Puyallup people, known in their language as the spuyaləpabš, meaning "generous and welcoming behavior to all people (friends and strangers) who enter our lands." The first white settlers in the region were part of the first wagon train to cross the Cascade Range at Naches Pass in 1853. Native Americans numbered about 2,000 in what is now the Puyallup Valley in the 1830s and 1840s. The fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cascade Range
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington (state), Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as many of those in the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The highest peak in the range is Mount Rainier in Washington at . part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from the Cascade Volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a 1980 eruption of Mount St. Helens, major eruption of Mount St. Helens in 1980. Minor eruptions of Mount St. Helens have also occurred since, most recently from 2004 to 2008. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
