  • Community Risk Assessment
    COMMUNITY RISK ASSESSMENT Squamish-Lillooet Regional District Abstract This Community Risk Assessment is a component of the SLRD Comprehensive Emergency Management Plan. A Community Risk Assessment is the foundation for any local authority emergency management program. It informs risk reduction strategies, emergency response and recovery plans, and other elements of the SLRD emergency program. Evaluating risks is a requirement mandated by the Local Authority Emergency Management Regulation. Section 2(1) of this regulation requires local authorities to prepare emergency plans that reflects their assessment of the relative risk of occurrence, and the potential impact, of emergencies or disasters on people and property. SLRD Emergency Program [email protected] Version: 1.0 Published: January, 2021 SLRD Community Risk Assessment SLRD Emergency Management Program Executive Summary This Community Risk Assessment (CRA) is a component of the Squamish-Lillooet Regional District (SLRD) Comprehensive Emergency Management Plan and presents a survey and analysis of known hazards, risks and related community vulnerabilities in the SLRD. The purpose of a CRA is to: • Consider all known hazards that may trigger a risk event and impact communities of the SLRD; • Identify what would trigger a risk event to occur; and • Determine what the potential impact would be if the risk event did occur. The results of the CRA inform risk reduction strategies, emergency response and recovery plans, and other elements of the SLRD emergency program. Evaluating risks is a requirement mandated by the Local Authority Emergency Management Regulation. Section 2(1) of this regulation requires local authorities to prepare emergency plans that reflect their assessment of the relative risk of occurrence, and the potential impact, of emergencies or disasters on people and property.

  • 4.3.3 Hazard Mapping
    4.3 Hazard mapping roads have untreated faces of slopes after being cut, on which rock falls and minor slope collapses frequently occur. Some of the bridges are prone to dangers of scouring. For the flood control and water quality, the catchment area management is important. Guatemala is a well-developed agricultural country that uses a large part of slopes as farmland. A slope with an inclination of 15 degrees or more tends to have significant washout of soil, causing debris flows and floods. The development on the mountainside of Agua volcano is considered to be one of the causes for the debris flow disaster that occurred in Ciudad Vieja in June 2002. Some major tasks to be completed remain such as assistance for tree planting in the upper reaches, restrictions on land use based on land use evaluation along rivers, setup of planned flood discharges, and planning for constructing revetments and embankments. 4.3.3 Hazard mapping (1) Methods of hazard mapping Two approaches to the estimation of hazardous areas are available, namely by evaluating the accumulation of events in which the past disasters occurred and by estimating the range of influence through a simulation based on certain conditions. The empirical methods which allows to relatively rank the potential hazard of a point or area, may be adopted to establish land use plans. This approach has also the merit to avoid getting a wrong hazard estimation being itself concerned with cumulative hazard levels. The simulation also allows estimating the hazardous areas with various disaster types, disaster scales, and occurrence locations by changing the disaster occurrence conditions.

  • The 1985 Nevado Del Ruiz Volcano Catastrophe: Anatomy and Retrospection
    Journal of Volcanology and Geothermal Research, 42 (1990) 151-188 151 Elsevier Science Publishers B.V., Amsterdam--Printed in the Netherlands The 1985 Nevado del Ruiz volcano catastrophe: anatomy and retrospection BARRY VOIGHT Penn State University, University Park, PA 16802, U.S.A. (Received December 1, 1989) Abstract Voight, B., 1990. The 1985 Nevado del Ruiz volcano catastrophe: anatomy and retrospection. In: S.N. Williams (Editor), Nevado del Ruiz Volcano, Colombia, II. J. Volcanol. Geotherm. Res., 42: 151-188. This paper seeks to analyze in an objective way the circumstances and events that contributed to the 1985 Nevado del Ruiz catastrophe, in order to provide useful guidelines for future emergencies. The paper is organized into two principal parts. In the first part, an Anatomy of the catastrophe is developed as a step-by-step chronicle of events and actions taken by individuals and organizations during the period November 1984 through November 1985. This chronicle provides the essential background for the crucial events of November 13. This year-long period is broken down further to emphasize essential chapters: the gradual awareness of the awakening of the volcano; a long period of institutional skepticism reflecting an absence of credibility; the closure of the credibility gap with the September 11 phreatic eruption, followed by an intensive effort to gird for the worst; and a detailed account of the day of reckoning. The second part of the paper, Retrospection, examines the numerous complicated factors that influenced the catastrophic outcome, and attempts to cull a few "lessons from Armero" in order to avoid similar occur- rences in the future.

Evaluating seismic hazard communication – the Swiss case Michèle Marti1, Michael Stauffacher2, Stefan Wiemer1 1Swiss Seismological Service, ETH Zurich, Zurich, 8092, Switzerland 5 2USYS TdLab, ETH Zurich, Zurich, 8092, Switzerland Correspondence to: Michèle Marti ([email protected]) Abstract 2.7 billion people live in areas where earthquakes causing at least slight damage have to be expected regularly. Providing 10 information can potentially save lives and improve the resilience of a society. Maps are an established way to illustrate natural hazard. Despite of being mainly tailored to the requirements of professional users, they are often the only accessible information to help the public deciding about mitigation measures. There is evidence that hazard maps are frequently misconceived. Visual and textual characteristics as well as the manner of presentation have been shown to influence their comprehensibility. Using a real case, the material to communicate the updated seismic hazard model for Switzerland was 15 analyzed in a representative online survey of the population (N = 491) and in two workshops involving architects and engineers not specializing in seismic retrofitting (N = 23). Although many best practice recommendations have been followed, the understanding of seismic hazard information remains challenging. Whereas most participants were able to distinguish hazardous from less hazardous areas, correctly interpreting detailed results and identifying the most suitable set of information for answering a given question proved demanding. We suggest scrutinizing current natural hazard communication strategies 20 and empirically testing new products.

Executive Summary Cilacap district (Kabupaten) is considered as one of the high risk areas regarding tsunami hazard in Indonesia because a large tsunami within range of Cilacap would have a severe impact on its densely populated coastlines. Many of Cilacap’s major development areas and especially the oil-mining industry is located directly on the shorelines facing the Indian Ocean. Below the same ocean, a couple of hundred kilometres south of Cilacap, lies one of the Earth’s major tectonic collision zones, which is a major source of tsunamigenic earthquakes. Thus, geologists and tsunami scientists consider Cilacap a high risk tsunami area.
