Jiujiufeng
Jiujiufeng ( zh, t=九九峰, p=Jiǔjiǔfēng, l=ninety-nine peaks) is a nature reserve located at the border of Taichung City and Nantou County, spanning the cities of Caotun, Guoxing, Wufeng, and Taiping. The protected area contains many small, jagged peaks, hence the name. Description Jiujiufeng is located on the north bank of the Dadu River southeast of Taichung City. Geologically, Jiujiufeng is located in the Toukeshan Formation (頭嵙山層), a Pleistocene-era formation primarily composed of gravelly rocks. Since the soil has high permeability, the peaks are easily eroded by rainfall to form the jagged peaks. Despite the terrain, Jiujiufeng still sustains a wide array of plant life, including the rare '' Reevesia formosana''. The 1999 Jiji earthquake caused many landslides within Jiujiufeng, which uncovered the red laterite surfaces beneath and destroyed much of the original vegetation. The resulting unique landscape prompted the Forestry Bureau to protect it as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Huoyan Mountain
Huoyan Mountain ( zh, t=火炎山, p=Huǒyánshān, l="fire mountain") is a mountain located at the border of Sanyi and Yuanli Townships in Miaoli County, Taiwan. The mountain is known for its jagged exposed laterite surfaces that look like fire. Description Huoyan Mountain is located on the north bank of Da'an River. Geologically, it is part of the Toukeshan Formation (頭嵙山層), a Pleistocene-era formation. The prominent red cliffs on the mountain are due to the tectonic uplift, weak shear strength of the underlying soil, and heavy rainfall. The mountain is protected by the Forestry Bureau to preserve the unique landscape and ecology. County Highway 140, a major road connecting the coastal regions with the mountainous interior in Miaoli County, passes on the south side of the mountain. In the past, the highway would often be blocked by landslides triggered by heavy rainfall. Therefore, in 2006, a tunnel was built to protect the road from blockages. Hiking There are ...

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiking Trail
A trail, also known as a path or track, is an unpaved lane or small road usually passing through a natural area. In the United Kingdom and the Republic of Ireland, a path or footpath is the preferred term for a pedestrian or hiking trail. The term is also applied in North America to routes along rivers, and sometimes to highways. In the US, the term was historically used for a route into or through wild territory used by explorers and migrants (e.g. the Oregon Trail). In the United States, "trace" is a synonym for trail, as in Natchez Trace. Some trails are dedicated only for walking, cycling, horse riding, snowshoeing or cross-country skiing, but not more than one use; others, as in the case of a bridleway in the UK, are multi-use and can be used by walkers, cyclists and equestrians alike. There are also unpaved trails used by dirt bikes and other off-road vehicles, and in some places, like the Alps, trails are used for moving cattle and other livestock. Usage In ...

Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Tropic of Cancer, Cancer and Tropic of Capricorn, Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to c ...

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the shear strength of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1999 Jiji Earthquake
The Chi-Chi earthquake (later also known as the Jiji earthquake) (), also known as the great earthquake of September 21 (), was a 7.3 ML or 7.7 Mw earthquake which occurred in Jiji (Chi-Chi), Nantou County, Taiwan on Tuesday, 21 September 1999 at 01:47:12 local time. 2,415 people were killed, 11,305 injured, and billion worth of damage was done. It is the second-deadliest earthquake in Taiwan's recorded history, after the 1935 Shinchiku-Taichū earthquake. Rescue groups from around the world joined local relief workers and the Taiwanese military in digging out survivors, clearing rubble, restoring essential services and distributing food and other aid to the more than 100,000 people made homeless by the quake. The disaster, dubbed the "Quake of the Century" by the local media, had a profound effect on the economy of the island and the consciousness of the people, and dissatisfaction with government's performance in reacting to it was said by some commentators to b ...

Gravel
Gravel is a loose aggregation of rock fragments. Gravel occurs naturally throughout the world as a result of sedimentary and erosive geologic processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. In the Udden-Wentworth scale gravel is categorized into granular gravel () and pebble gravel (). ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm to 20–63 mm. One cubic metre of gravel typically weighs about 1,800 kg (or a cubic yard weighs about 3,000 lb). Gravel is an important commercial product, with a number of applications. Almost half of all gravel production is used as aggregate for concrete. Much of the rest is used for road construction, either in the road base or as the road surface (with or without asphalt or other binders.) Naturally occurring porous gravel deposits have a ...

Pleistocene
The Pleistocene ( , often referred to as the '' Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the t ...
