Abstract

The major earthquake on April 25, 2015 (7.8 Mw) and the aftershock on May 12, 2015 (7.3 Mw) caused severe damages on Kathmandu University (KU) Library. Disaster prevention of the library building is necessary to restore its strength and reduce seismic risk. Retrofitting approach can be employed to strengthen the building and increase its seismic capacity. Seismic retrofit is an effective technique by which the building can be strengthened to improve its seismic performance without affecting its aesthetics value and architectural identity. To achieve public safety by considering use of various materials and structural stability, retrofitting is economically applied to meet functional and structural requirements of the building. This pro-active disaster mitigation technique has been effective in modifying the existing structure for strengthening to improve its structural performance.

Abstract

Nepal is one of the 20 most disaster-prone countries in the world. More people are killed by disasters in Nepal than in any other country in South Asia, making Nepal extremely vulnerable to different types of natural disasters like earthquakes, floods, landslides, fire, drought and others. Hence, people faces big or small impact on overall. The aim of the article is to identify the impact of recent earthquake of 25th April and May 12th, 2015 on Nepalese economy and women in Nepal. The article is based on secondary information as published by different sources and further the article updates on economic loss of Nepal due to earthquake and it impact on Nepalese economy and women. It traces the historical background of the earthquake, which occurred in Nepal and follows to identify the impact of recent earthquake on people and properties (damaged by partially and fully). It also presents the loss on various sectors like social, productive, infrastructure and cross cutting sectors, which are indicator of Nepalese economy before and after earthquake. The article also further focuses on the requirement of resources to reconstruct and recover the damaged and lost sectors, concluding that the recent earthquake has greatly impact on Nepalese economy and women.

Abstract

The devastating 25 April, 2015 earthquake in Nepal has affected a total of 1.4 million women and girls of reproductive age in the 14 most affected districts in which 93,000 were pregnant at the time of the earthquake, with 10,000 delivering each month requiring emergency obstetric care and 1,000 to 1,500 at risk of pregnancy related complications necessitating cesarean sections. Malnutrition and poverty hit women the hardest due to their longer working hours at work and home with limited access of education, health care, and involvement in local and state government. The midwifery society of Nepal (MIDSON) has established Help Desk for a week in national maternity hospital and served 100 women with the various problems of miscarriage, less fetal movement, bloody discharge, false labor pain, transportation problem to back home etc. Latter on MIDSON has expanded with support of UNFPA to conduct mobile RH camps with Minimum Initial Service Package (MISP) to protect women and girls in Nuwakot district. 25 nurse midwives were deployed in six affected districts for 3 months with support of UNICEF.

Abstract

The Mw 7.8 Gorkha earthquake of 25 April 2015 and its many severe aftershocks generated about 4000 landslips. We have carried out field investigation of mass movements in the most severely-affected six districts of Central Nepal. The study revealed that the size and distribution of slides is strongly controlled by their position on landscape. An overwhelming majority of them was less than 5 m deep. Many slides were found to originate near a long and high crest or a peak. The slopes that had the highest internal relief suffered the most from the seismically-triggered failures. On the other hand, the old and large failures that were confined mainly to the river valleys were rather insensitive to earthquake shaking.

Abstract

This paper describes the damage brought by the 2015 Nepal earthquake to urban infrastructures, modern and traditional buildings as well as some word heritage sites in and around Kathmandu city. The paper also focuses on a disaster brought to a hydropower plant by the compound action of a previous landslide and this time earthquake. Some of the possible reasons for such damage were brought to light, and challenges of the geotechnical community towards the retrofitting and recovery of the devastated structures were discussed

Abstract

Extreme natural disasters are events caused by environmental factors that injure, displace people and damage property. On 25th April 2015 a devastating earthquake of 7.8 on Richter scale struck Nepal causing approximately 9,000 deaths and damage to 900,000 houses. Homeless victims are doomed to live in temporary shelters. In the context of Nepal, after the massive earthquake, no research is done to evaluate the thermal environment in temporary shelters and thermal comfort of habitants. Thermal measurements and thermal comfort surveys were conducted to find out the actual conditions of thermal environment in the temporary shelter and thermal comfort status of respondents. The surveys were carried out for 30 days in autumn covering 202 residents. The mean indoor temperature is 21.1 °C, which is similar to the globe temperature. From the analysis we found that mean day time and night time indoor air temperatures are 18.7 °C and 15.2 °C respectively. The comfort temperature in the temporary shelter is 23.9 °C and the mean clothing insulations of residents is 0.73 clo. The result indicates that the indoor air temperature in the temporary shelter is considerably low in autumn season but residents are maintaining thermal comfort by using various behavioral adaptations.

Abstract

Large landslide dams are one of the most destructive natural phenomena. They frequently occur in tectonically active orogenic belts with narrow and steep valleys. Nepal hosts many large landslide dams, some of which must have been caused by past earthquakes. The Mw 7.8 Gorkha Earthquake of 25 April 2015 and its aftershocks triggered off many shallow failures with only a few landslide dams that were either very short-lived or only partially blocked the river course. The area affected by the earthquake belongs to the Lesser Himalayan Sequence, Higher Himalayan Crystallines, and the Tethyan Himalayan Sequence. The severely affected area is made up of such resistant rocks as quartzites, gneisses, granites, marbles, and schists. These rocks have generally three discontinuity sets, which are almost perpendicular to each other. A detailed analysis of dip slopes, anti-dip slopes, and dip-normal slopes in the earthquake-affected area revealed that the dip-normal slopes were the most vulnerable ones. Many rockslides and rock falls began from the crest and created long runout paths. The potential sites of landslide damming can be inferred by analysing morphometric parameters together with seismic, geological, hydro-meteorological, and anthropogenic factors. Such damming sites were identified heuristically at various locations of the major rivers, based on the criteria discussed above. Since the earthquake-triggered failures were concentrated mainly on steep slopes with a high internal relief, a hazard map was prepared by combining the safety factor map with the slope map and the internal relief map. There is a good correspondence between the high hazard zones and the heuristically identified potential sites of landslide damming

Abstract

The strong earthquake on April 25, 2015 (7.8 Mw) and the aftershock on May 12, 2015 (7.3 Mw) claimed the lives of 8,659 people, plus 21,150 people injured and huge economic loss together with serious damages on eight World Heritage sites. Our two field surveys in the month of from May 9-21, 2015 and 19-23 July, 2015 revealed understanding of damages to traditional towns, historical monuments, and modern buildings. Regionally, damages on buildings are confined to the traditional houses which are remnants of or renovated after the 8.1 magnitude 1934 AD earthquake. Widespread cases of inadequate engineering and construction practices for RCC (Reinforced Cement Concrete) buildings and renovated old buildings have been severely affected. The affected region includes the main shock along the 150 km long rupture zone towards east. The aftershock reached farther south at a shallower depth towards the end of the eastern rupture zone. As a result damages inflicted in the structures from both quakes revealed different shaking directions. The April 25 main shock caused eastward leaning structures while May 12 aftershock caused southward leaning and/collapsed structures. It is important to identify whether the direction is due to aftershock at the end of initial rupture zone or if it represents a newly exposed fault.

Abstract

The 2015 Nepal M 7.8 Earthquake and M 7.2 Aftershock caused catastrophic damage across a large area of strong shaking and impacting the entire nation. This paper presents best practices in evaluating core community functions in need, and planning for rapid and resilient recovery, building back better. Several tools and methods are explained including the concept of lifeline infrastructure resilience and performance goals under the 2015 United States (US) National Institute for Standards and Technology (NIST) Community Resilience Planning Guide; use of HazusMH loss modeling software adapted to measure losses avoided from modern hazard resistant building code provisions; and a framework for success using the new United Nations Disaster Resilience Scorecard, developed by IBM and AECOM, now piloted in over 30 cities since 2014 rollout. The utilization of the UNISDR scorecard for Kathmandu indicates the applicability of these techniques in evaluating the resilience of key infrastructure and institutional facilities, and how they can be an effective tool in planning and Disaster Risk Reduction.
