Transcript of "BHUJ EARTHQUAKE"

  1. 1. ACKNOWLEDGEME NTWE GREATFULLY WANT TOACKNOWLEDGE AND GIVE THANKS TOOUR SPEACIAL SOCIAL TEACHER ANDRESPECTED SIR TO GIVE US SUCH AGREAT OPPORTUNITY BY GIVING US THETASK TOPREPARE A POWERPOINT PRESENTATIONIN WHICH WE HAVE TRIED TO MAKEPEOPLE KNOW ABOUT IT AND DEVELOPOUR KNOWLEDGE .
  2. 2. THE BHUJ EARTHQUAKE OCCURRED ON 26JANUARY 2001 ON THE INDIA’S 51 REPUBLICDAY.IT WAS VERY VERY HUGE ANDDISASTEROUS AND CAUSE MANYDEATHS.PEOPLE TODAY ALSO REAMEMBERABOUT THAT AS IT HAS LEAVED VERY BIGIMPACT ON THEM. ABOUT 20,000 PEOPLEWERE KILLED AND ABOUT 167,000 WEREINJURED AND 40,000 HOMES WEREDESTROYED.THE EARTHQUAKE WAS 6.9 ON RICHTERSCALE
  3. 3. Date The 2001 Gujarat earthquakeJanuary 26, 2001 (2001- occurred on January01-26) 26, 2001, Indias 51st RepublicMagnitude Day, at 08:46 AM local time (3:167.7 Mw[1] UTC) and lasted for over twoDepth minutes. The epicentre was about 916 kilometres (10 mi) km south-southwest of the villageEpicenter location of Chobari[3] in Bhachau Taluka ofYellow star marks Kutch District of Gujarat, India.[4]epicentre The earthquake reached aCountries or regions magnitude of between 7.6 and 7.7affected on the moment magnitude scale India and had a maximum felt intensity ofMax. intensity X (Intense) on the Mercalli intensityX (Intense) scale. The quake killed aroundCasualties 20,000 people (including 18 in19,727 believed South eastern Pakistan), injureddead, 166,001 injured [3] another 167,000 and destroyed nearly 400,000 homes.[5]
  4. 4. DESCRIPTI ON The 2001 Gujarat earthquake occurred on January 26, 2001, Indias 51st Republic Day, at 08:46 AM local time (3:16 UTC) and lasted for over two minutes. The epicentre was about 9 km south-southwest of the village of Chobari[3] in Bhachau Taluka of Kutch District of Gujarat, India.[4] The earthquake reached a magnitude of between 7.6 and 7.7 on the moment magnitude scale and had a maximum felt intensity of X (Intense) on the Mercalli intensity scale. The quake killed around 20,000 people (including 18 in South eastern Pakistan), injured another 167,000 and destroyed nearly 400,000 homes.[5] This was an intraplate earthquake, one that occurred at a distance from any plate boundary where plate tectonics create most earthquakes, so the area was not well prepared. The event was the result of stored energy in a collision margin. The shock waves spread 700 km. 21 districts were affected and 600,000 people left homeless.
  5. 5.  The four urban centers of Kachchh namely Anjar, Bhuj, Bhachau and Rapar were replanned after the earthquake. The Bhuj city which had an area of 19 square kilometer before the earthquake was expanded to an area of 56 square km. Three relocations sites were developed to decongest the inner city of Bhuj. The names of these sites are- rawalwadi, RTO and Mundra site. The final death toll in Kutch was 12,290 Bhuj, situated only 20 kilometres (14 miles) from the epicenter, was devastated. Considerable damage also occurred in Bhachau and Anjar with hundreds of villages flattened in Taluka of Anjar, Bhuj & Bhachau. Over a million structures were damaged or destroyed, including many historic buildings and tourist attractions.[6] The quake destroyed around 40% of homes, eight schools, two hospitals and 4 km of road in Bhuj and partly destroyed the citys historic Swaminarayan temple. In Ahmedabad, Gujarats commercial capital with a population of 4.6 million, as many as 50 multi-storied buildings collapsed and several hundred people were killed. Total property damage was estimated at $5.5 billion and rising. The earthquake destroyed 60% of usable food and water supplies in Kutch. The district collector Anil Mukim oversaw the early delivery of aid and equipment to affected villages but later called for aid to cease as it encouraged a "relief mentality" which would delay a return to normal life.[7]
  6. 6. CAUSES OF THE EARTHQUAKEBhuj earthquake of 26 January 2001: Tectonic inversion, lithospheric flexure and plate motion andcomparison with Shillong and New Madrid earthquakes The Bhuj earthquake of 26 January 2001(Figure 1) of Mw 7.6, with focal depth of24–25 km was o of the most devastatingearthquakes outside plate boundaries. Variousseismological studies have suggestedthat it is caused by an E–W-orientedthrust1–3. Kachchh rift basin basically developedduring the Mesozoic period4 andis therefore characterized by an extensionalphase followed by a compressionalphase during closure of the basin. In thisrespect, it is analogous to the New Madridearthquake of 1811–12 in USA of almostthe same magnitude, and both the eventshave often been compared with each other5,6.But there are also several differences between the two, the most important being their distance with respectto plate boundaries.is within 200–300 km of the plate boundary(inset, Figure 1) while that of the New The epicentre of the Bhuj earthquakeMadrid earthquake is at least 2000 kmaway from any known plate boundary.However, the epicentral areas of both theseearthquakes have been associated withPrecambrian–Cambrian collision zones relatedto Aravalli–Delhi and Appalachianorogeny respectively. Such zones worldover are weak, characterized by seismicactivity.
  7. 7.  The epicenter was near the remote Little Rann of Kutch, but within 150 to 200 kilometers of several villages and towns. The proximity to populated areas, coupled with a shallow 17- kilometer focus, resulted in massive destruction and fatalities. The area is mainly barren, with the exception of a belt of arable land stretching along the shore of the Gulf of Kachchh. The affected area also experienced magnitude 5.0 to 5.8 aftershocks for several days subsequent to the main earthquake (
  8. 8. Bhuj earthquake and its tectonic setting  The Mw=7.7 earthquake occurred in the morn-ing of January 26, 2001, on the Republic Day of India. The epicenter is located at 23.40ºN and 70.32ºE near Bhuj in the province of Gujarat, India (Fig. 2). The official death toll from the India government was close to twenty thousand [Bendick et al., 2001]. Thousands of houses were destroyed and more than half million of people were left homeless. Initial results indicate a shallow (~20 km) focal depth, with a roughly E-W trending thrust fault plane [NEIC; Gaur et al., 2001]. Based on the aftershock data, the rapture was estimated to have occurred along a plane with a 50-100 km along-strike length and 15-30 km down-dip rap-ture width. The slip was 1-4 m, reaching ~12 m near the hypocenter [Antolik and Dreger, 2001; Bendick et al., 2001]. This event apparently caused few surface scarps [EERI, 2001; Rajen-dran et al., 2001].
  9. 9. DAMAGE CAUSED BY EARTHQUAKE The 26 January 2001 earthquake in Gujarat was the most devastating seismic event to affect the state since the last magnitude 7.7 event in 1819. More than 20,000 people died and over 167,000 injuries were reported. Both rail and highway traffic into and out of the entire Kachchh region was completely cut off for two days. Numerous bridges, dams, and ports were destroyed or severely damaged as a result of liquifaction of the blue marine clay soil on which they are constucted. Approximately 1,000,000 homes were destroyed or seriously damaged, as were many commercial, industrial, and public utility facilities. Total blackout resulted in several towns and villages; communications in Bhuj were disrupted for two days when fiber optic cables were damaged, and water supplies were affected as liquifaction caused some wells to become turbid and others tested positive for metal contaminants and anaerobic sludge .
  10. 10. DAMAGES BY EARTHQUAKE2001
  11. 11. PEOPLE AFFECTED BY EARTHQUAKE  Many people were affected by the bhuj earthquake 2001 which was about 6.9 on richter scale.more than 20,000 people died and over 18,000 people were injuried.most of the people lost their houses and family and were badly affected.the earthquake caused death of about 100 persons and injured hundrends more.
  12. 12. BY THIS PRESENTATION WE CONCLUDETHAT -IT WAS VERY DANGEROUS AND SO WESHOULD PRAY TO GOD THAT NEXTTIME THEY MAY NOT COME AND ALSOGOVERNMENT SHOULD TAKE STEPSTO RECOVER THE DAMAGES CAUSED BYIT AND ALSO TO SAVE THE PEOPLEAFFECTED BY SUCH DISASTERS . THEGOVERNMENT CAN ALSO PROVIDE SOMEMONEY TO THE PEOPLE WHO SURVIVEDSO THAT THEY CAN GO ANYWHERE ELSEAND MANAGE THERE
