Committee of Experts to examine the seismic problem and make appropriate recommendations. The Committee proposed a zoning map of Bangladesh in the same year. According to Bangladesh National Building Code (BNBC‚ 1993)‚ Bangladesh is divided into 3 earthquake zones (Figure- 6): Zone –1: the less risky zone. The Zone-1 comprising the southwestern part of Bangladesh (Jessore‚ Khulna and Barisal Districts) is seismically quiet‚ with an estimated basic seismic co-efficient of 0.04. Zone–2: medium vulnerable

your head so as to keep it lower than the back. If possible‚ keep your hands above your head while you bend. Avoid stairs Never go to the stairs as this is the first part of a building to be damaged. Even if they are not destroyed by the earthquake‚ they may well collapse with the weight of panicking people attempting to flee down them. Avoid the bottom floor The higher you are in a building the less weight will be crushing down upon you and the safer you will be. Avoid doorways

I chose to research earthquakes and the prediction of earthquakes because I was curious as to how they work. In this paper‚ I will discus the history of earthquakes‚ the kinds and locations of earthquakes‚ earthquake effects‚ intensity scales‚ prediction‚ and my own predictions. An earthquake can be defined as vibrations produced in the earth’s crust. Tectonic plates have friction between them which builds up as it tries to push away and suddenly ruptures and then rebounds. The vibrations

Hazard Monitoring And Disaster Reduction EM-DAT It’s a global database on natural disasters that contains essential data on the occurrence and effects of more than 17‚000 disasters in the world from 1900 to present. The database is compiled from various sources‚ including UN agencies‚ non-governmental organisations‚ insurance companies‚ research institutes and press agencies. It’s data is primarily used by governments and agencies in charge of relief and recovery after a disaster. In addition

Kobe Earthquake – Case Study Kobe Earthquake – Case Study In the early morning of January the 17th 1995 instruments in a lab in western Japan picked up a burst of intense electro-magnetic radiation. It was the signature of a massive earthquake which had just struck the City of Kobe from its epicentre 20 kilometres to the south west. There was no warning‚ 180‚000 buildings were destroyed‚ an urban area 20 kilometres long and 4 kilometres wide was totally wrecked. Nothing moved in or out of Kobe

tsunami/earthquake and the 2010 Haiti earthquake. Disaster 1 – Japanese Tsunami and Earthquake On Friday the 11th of March 2011‚ a magnitude 9.0 Earthquake struck coastal waters‚ along a subduction zone‚ surrounding Japanese islands. At the time of the Earthquake‚ no one expected what was about to occur‚ one of the most devastating tsunamis to have ever hit Japan. Earthquakes are caused by forces deep within the Earth when two blocks of the earth suddenly slip past one another.

Introduction: Briefly answer the question asked: “Why do similar kinds of hazards have different impacts in different places?” Talk about the risk vulnerability quadrant. Talk about the risk equation and how it will link to the question. P1: Point: Economic situation of the country affected by the disaster - Lots of money = better health cares to treat affected people. Little money = little spent to rebuild‚ plan‚ prepare‚ predict hazards so impact is greater. Explain: If they have more money than they

combination of earthquake and tsunami was a wakeup call reminding companies across the world how much they rely on nature to commerce business. On Friday 11 March 2011‚ an earthquake measuring 9.0 on Richter scale struck off Japan’s north-east coast of Tohoku which happened at 2:46pm (Alabaster et al. 2011). The massive earthquake was caused due to thrust faulting where rocks placed lower in the earth’s crust get pushed over the overlying layers (Alabaster et al. 2011). After the earthquake‚ the shadow

Earthquakes in Australia Australia is a very lucky country that suffers very few earthquakes or volcanic eruptions. Earthquakes are caused by converging plates (usually subducting)‚ and there a 4 different types of waves in two categories; firstly there is Body waves which are broken into primary and secondary waves (these travel through the earth) Surface waves travel through only the crust and are called Love and Rayleigh. These Waves (the earthquakes) are measured by a seismograph/ a device that
