More broadly, this initiative offers support to long-term, core economic, and social developmen t objectives. The risk mo deling undertaken through SWIO RAF I focused on th ree pe rils: tropical cyclones, floods produced by eve nts other than tropical cyclones, and earthquakes. Three hazards associated with tropical cyclones, wind, flooding and storm surge were considered in the risk assessment. In addition, as part of the earthquake risk assessment, tsunami risk zones were identified for each country. DISASTER RISK PROFILE I INTROOUCTION 1 hiS analys is suggests th at, on average, Comoros experiences nearly US$S.7 mi llion in combined direct Tlosses from earthquakes, floods. a nd tropical cyclones each year. However,a specific event such as a severe tropical cyclone can prod uce significantly larger losses. For example. Key Facts results suggest that a lOO-year return period tropical cyclone This ana lysis suggests that: event cou ld pro duce direct losses of $43 million and require approximately $9.9 million in emergency costs. • The average annual direct losses from earthquakes, l100ds, and Tropical cyclones are by far the most significant risk of the tropical cyclones are $5.7 million. three perils in this study, causing approximately 64 percent of the average loss per year. Flooding is the next largest risk. • The tun-year return period loss accounting for nearly 35 percent. It is important to note that an from all perils is over $48 million, I important risk on Grande Comcre, the Karthala volcano, was not or nearly 8% of Comoros's 2014 included in this analysis. • ~ l GOP. e In this analysis the residential sector experiences 80 percent • The 2S0-year return period loss of the combined losses, the public sector over 11 percent, and from all perils could be $150 the commercial sector nearly 6 percent. The highest loss takes million, or 24% ofComoros's 2014 place in Anjouan, which experiences nearly 80 percent of GDP. the average annual losses from the three perils combined In addition to the direct losses, an annual average of nearly $ 1.3 million is estimated for emergency costs.
