The Himalaya, the youngest and the tallest folded mountain range of the world, is frequently affected by natural disasters.18 In the form of flash floods, cloudbursts or glacial lake outburst floods, the entire Himalayan region is highly vulnerable to natural hazards. In this context, the State of Uttarakhand of the Indian Himalayan Region has been the most vulnerable one among all the natural disaster-affected states in India.

This chapter is about what glaciers—and particularly what glacial and periglacial melt—mean to people and communities around the world. We often don’t realize that people interact daily with glaciers. Some go to visit and hike on glaciers or to photograph them for their magnificent beauty. Some ski on glaciers. Others extract water from glaciers for personal and industrial use. Others fear glaciers for their potent fury and destruction. People and communities are adapting to climate change and its impacts on glaciers, sometimes without even knowing it. Others are very aware of glacier vulnerability and are taking measures to address the changing cryosphere. They are mitigating circumstances and are adapting to impacts. In this chapter, we share stories and facts about glaciers and periglacial environments, which most people are probably unfamiliar with, and we explain how lives in these environments are changing due to climate change. Few people have heard of glacier tsunamis, but they exist, they’re real, they’re ferocious, and they can kill. Scientists call them glacier lake outburst floods (GLOFs). And as climate change deepens, more and more GLOF phenomena can be expected. Imagine you live at the foot of a mountain range like the Rocky Mountains, the Himalayas, or the Central Andes. On a nice sunny day, you can see the snow-capped mountains in the distance, maybe 20 or 30 km (12–18 mi) out, maybe even more. You are sitting at home when all of a sudden you feel shaking and hear a rumble. People start screaming. You look out the window and see people running frantically and erratically about. Then a woman yells, “The mountain! It’s coming! Run!” Imagine a large glacier the size of a dozen or so city blocks, perched atop a mountain. It’s 180 meters thick (600 ft), which is as tall as a sixty-story building. Below it, time and climate have formed a lake, a glacier lake occupying the same spot where the glacier once rested, pushing rock and earth out and forward as the glacier flowed downhill when it was solidly frozen and healthy.

Abstract The Himalaya are among the youngest and highest mountains in the world, but the exact timing of their uplift and origins of their biodiversity are still in debate. The Himalayan region is a relatively small area but with exceptional diversity and endemism. One common hypothesis to explain the rich montane diversity is uplift-driven diversification–that orogeny creates conditions favoring rapid in situ speciation of resident lineages. We test this hypothesis in the Himalayan region using amphibians and reptiles, two environmental sensitive vertebrate groups. In addition, analysis of diversification of the herpetofauna provides an independent source of information to test competing geological hypotheses of Himalayan orogenesis. We conclude that the origins of the Himalayan herpetofauna date to the early Paleocene, but that diversification of most groups was concentrated in the Miocene. There was an increase in both rates and modes of diversification during the early to middle Miocene, together with regional interchange (dispersal) between the Himalaya and adjacent regions. Our analyses support a recently proposed stepwise geological model of Himalayan uplift beginning in the Paleocene, with a subsequent rapid increase of uplifting during the Miocene, finally give rise to the intensification of the modern South Asia Monsoon.

This study explores twitter data about insurance and natural disasters to gain business insights using text analytics. The program R was used to obtain tweets that included the word ‘insurance' in combination with other natural disaster words (e.g., snow, ice, flood, etc.). Tweets related to six top Canadian insurance companies as well as the top five insurance companies from the rest of the world, including the new entrant Google Insurance, was collected for this study. A total of 11,495 natural disaster tweets and 19,318 insurance company tweets were analyzed using association rule mining. The authors' analysis identified several strong rules that have implications for insurance products and services. These findings show the potential text mining applications offer for insurance companies in designing their products and services.

The occurrence of several cases of natural disaster and its impact on high-risk regions remains an issue that continues to attract continued research, most especially from a global perspective. Despite the devastating impact of several known natural phenomenon such as flooding, tsunamis, earthquakes, glaciers and tornadoes, there seem not to be well-structured disaster management approach from stakeholders in high-risk disaster-prone regions to cope with eventual disaster cases. The Indian Himalayan region under review within this research article has been conducted investigated, and a review on how the build of poorly constructed residences have impacted the lives of people living within this region. This article addresses this problem in a line with well-structured thematic sections that examines community resilience, effective stakeholder communication and community preparedness can result in effective disaster management approach.

As a practical theologian and researcher in the field of ‘natural’ disasters, as well as being a disaster responder chaplain, I am often confronted by, and have to confront, the nexus between theology/philosophy and “real life” in extremely traumatic contexts. The extreme suffering that is often the consequence of catastrophic natural disasters warrants solutions that can help vulnerable populations recover and adapt to live safely with natural hazards. For many practice-based responders, speculative theological/philosophical reflections around situations that are often human-caused seem predominantly vacuous exercises, potentially diverting attention away from the empiricism of causal human agency. In this article, I explore a middle ground involving a nuanced methodological approach to theodicy that is practical but no less intellectually demanding, that is theological more than philosophical, practical more than theoretical; a middle ground that also takes seriously the human culpability as causal for the human, and some would say the divine, suffering from disasters. I will include in this exploration my ethnographic fieldwork following the catastrophic earthquake to hit the Caribbean nation of Haiti in 2010.

IntroductionChina is one of the countries most affected by disasters caused by natural hazards. Disasters comprise an important restricting factor for economic and social development.MethodsRetrospective analysis was performed based on the epidemiological data of disasters caused by natural hazards in recent two decades.ResultsThe deadliest disaster that was reviewed was the Sichuan, Wenchuan earthquake on 12 May 2008 with a death toll of 88,928. Floods were the the primary natural hazard resulting in disaster in China. The economic loss caused by natural disasters was huge, the Sichuan earthquake alone resulted in an economic loss of 845.1 billion Chinese Yuan. However, psychosocial factors did not receive attention by Chinese Government and academics.ConclusionsThe characteristics and impact of disasters should be analyzed to scientifically provide useful information for natural disaster mitigation in China.

Natural disaster that contributes to the economic crisis all over the world has a crucial role in emergency management. The assessment of regional risk to natural disasters is normally studied as a multi-criteria decision making (MCDM) problem in the literature. However little effort was devoted into the comparison of temporary disaster risk of regions. In this paper, a hybrid approach is proposed integrating MCDM and clustering for evaluating and comparing the regional risk to natural disasters. Our two-stage method is applied to thirty-one Chinese regions over the past two consecutive years. In the first stage MCDM is used to prioritize the regions yearly yielding a set of risk vectors over the given period. In the second stage, K-means clustering is applied to divide the regions into a number of clusters characterized by different risk variation patterns. The derived patterns reveal the variation of regions in perspective of natural disaster risk and therefore offer valuable suggestions for disaster risk reduction.

Abstract Social networking sites (SNS) became an indispensable part of people’s everyday life, but also a powerful tool of communication during urgent situations, such as during natural disasters. This is evidenced by a large number of research papers showing the use of SNS in difficult circumstances. Some of the ways of using are the dissemination of information about missing persons, warning on further possible consequences, safety checks during natural disasters, communication about places where the population can find help or a safe refuge. At the same time, SNS could increase awareness among the population about natural hazards. Unfortunately, most parts of the world have at least once been hit by a major natural disaster. People who manage such events have a big task in front of them, as they need to exploit the potential of SNS, but also to reduce the negative side, such as spreading inaccurate information in difficult moments. The paper presents ways of using SNS, and the positive and negative effects of these, before, during and after natural disasters.
