1905 Kangra Earthquake
The 1905 Kangra earthquake occurred in the Kangra Valley and the Kangra region of the Punjab Province (modern day Himachal Pradesh) in India on 4 April 1905. The earthquake measured 7.8 on the surface wave magnitude scale and killed more than 20,000 people. Apart from this, most buildings in the towns of Kangra, Mcleodganj and Dharamshala were destroyed. Background The calculated epicenter of the earthquake lies within the zone of thrusts along the front of the Himalayas formed by the continuing collision of the Indian plate into the Eurasian plate. Underthrusting of the Indian subcontinent beneath Tibet along a 2,500 km long convergent boundary known as the Main Himalayan Thrust has resulted in the uplifting of the overriding Eurasian Plate thus, creating the long mountain range parallel to the convergent zone. Earthquake characteristics The magnitude 7.8–7.9 earthquake struck the western Himalaya in the state of Himachal Pradesh at an estimated depth of 6 km ...

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rossi–Forel Scale
The Rossi–Forel scale was one of the first seismic scales to represent earthquake intensities. Developed by Michele Stefano de Rossi, Michele Stefano Conte de Rossi of Italy and François-Alphonse Forel of Switzerland during the late 19th century, it was used commonly for about two decades until the introduction of the Mercalli intensity scale in 1902. The Rossi–Forel scale and/or its modifications is still used in some countries, such as the Philippines until 1996 when it was replaced by the PHIVOLCS Earthquake Intensity Scale. Scale The 1873 version of the Rossi–Forel scale had 10 intensity levels: See also *Richter magnitude scale *Seismic intensity scales *Seismic magnitude scales Bibliography * Seismic intensity scales {{Seismology-stub ...

Earthquakes In India
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1897 Assam Earthquake
The Assam earthquake of 1897 occurred on 12 June 1897, in Assam, British India at 11:06 UTC, and had an estimated moment magnitude of 8.2–8.3. It resulted in approximate 1,542 human casualties and caused catastrophic damage to infrastructures. Damage from the earthquake extended into Calcutta, where dozens of buildings were severely damaged, with some buildings partially collapsing. Trembles were felt across India, reaching as far as Ahmedabad and Peshawar. Seiches were also observed in Burma. Earthquake The earthquake occurred on the south–southwest-dipping reverse Oldham Fault that forms the northern edge of the Shillong Plateau. There was a minimum displacement on the main fault of 11 m, although some calculations have placed this figure at as high as 16 m; one of the greatest for any measured earthquake. The calculated area of slip extended 180 km along the strike and from 9–45 km beneath the surface, indicating that the entire thickness of the c ...

Aqueduct (water Supply)
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term ''aqueduct'' is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term ''aqueduct'' also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water. Etymology The word ''aqueduct'' is derived from the Latin words (''water'') and (''led'' or ''guided''). Ancient aqueducts Although particularly associated with the Romans, aqueducts we ...

Chamba, Himachal Pradesh
Chamba is a town in the Chamba district in the Indian state of Himachal Pradesh. According to the 2001 Indian census, Chamba has a population of 20,312 people. Located at an altitude of above mean sea level, the town is situated on the banks of the Ravi River (a major tributary of the Trans- Himalayan Indus River), at its confluence with the Sal River. Though historical records date the history of the Chamba region to the Kolian tribes in the 2nd century BC, the area was formally ruled by the Maru dynasty, starting with the Raju Maru from around 500 AD, ruling from the ancient capital of Bharmour, which is located from the town of Chamba.Sharma & Sethi (1997), p.34 In 920, Raja Sahil Varman (or Raja Sahil Verman) shifted the capital of the kingdom to Chamba, following the specific request of his daughter Champavati (Chamba was named after her). From the time of Raju Maru, 67 Rajas of this dynasty ruled over Chamba until it finally merged with the Indian Union in April 194 ...

Bilaspur, Himachal Pradesh
Bilaspur is a town and a municipal council in Bilaspur district in the Indian state of Himachal Pradesh. History Bilaspur was the capital of a state of the same name founded in the 7th century, also known as Kahlur. The ruling dynasty were Chandel Rajputs, who claimed descent from the rulers of Chanderi in present-day Madhya Pradesh. The town of Bilaspur was founded in 1663. The state later became a princely state of British India, and was under the authority of the British province of Punjab. On 13 May 1665, Guru Tegh Bahadur went to Bilaspur to attend the mourning and funeral ceremonies for Raja Dip Chand of Bilaspur. Rani Champa of Bilaspur made an offer to the Guru of a piece of land in her state, which the Guru accepted at the cost of 500 rupees. The land consisted of the villages of Lodhipur, Mianpur, and Sahota. Guru Tegh Bahadur broke ground on a new settlement on 19 June 1665, which he named Nanaki after his mother. In 1932, the state became part of the newly cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
