Meteorological Assessment (highlighting forecasting issues/impacts) There were 4 Tropical Cyclones affected Lao PDR from 1st January to 31st October 2017 (Tracks as shown in figure 1) which are above normal data passing Lao PDR (normal 2 – 3 tropcal cyclones). These tropical cyclones were classified into 3 categories which impacted directly over Lao PDR, namely: Severe Tropical Storm Talas (1704), Tropical Storm Sonca (1708), Typhoon Doksuri (1719), and Tropical Depression. Figure 1: Tropical Cyclones Track for 2017 over Western North Pacific (1) Severe Tropical Storm Talas (1704): Talas was the first tropical cyclones of the year 2017 passed over Lao PDR and it was number 4 of the year 2017 over Western North Pacific Ocean. Talas was formed to a tropical disturbance over South China Sea during 13 July 2017. The next day around 6:00 UTC, it developed as a weak tropical depression and started to move slowly towards the northwest. -
Announcement on Revision of Reference Loss Cost Rates of Fire Insurance
Announcement on Revision of Reference Loss Cost Rates of Fire Insurance General Insurance Rating Organization of Japan (GIROJ) revised Reference Loss Cost Rates*1 of the fire insurance as below. *1 General insurance premium rates, which are the basis for general insurance premium, are composed of the “pure premium rates” and “Expense loading.” “Pure premium rates” correspond to the portion of rates allocated for future claims payments by insurers. GIROJ calculates advisory rates (Reference Loss Cost Rates) for this portion and provides them for the member insurers. Please refer to page 3 for details. 1. Outline of revision Reference Loss Cost Rates of the fire insurance (Homeowners’ Comprehensive Insurance) are to be 2 3 increased by an average of 10.9%.* * *2 When each insurer calculates “pure premium rates” for its own insurance products, they can use Reference Loss Cost Rates directly, they can use them with modification, or they can calculate original “pure premium rates” without using them, at their own discretion. Regarding the “Expense loading,” which is allocated for insurers’ business expenses and so on, each insurer calculates it independently. Therefore, the figures for revised rates of Reference Loss Cost Rates differ from revised rates of insurance products that policyholders purchase from insurance companies. *3 The rate of revision (average increase of 10.9%) above is an average of the rates for all the contract term combinations (prefecture, construction class, construction age, coverage, etc.). The rate of revision differs in accordance to the contract terms as shown in the “Section 3 Examples of percentage changes” on page 2. -

The results indicated that there were three distinct lightning flash regions in mature typhoon, a significant maximum in the eyewall regions (20–80 km from the center), a minimum from 80–200 km, and a strong maximum in the outer rainbands (out of 200 km from the cen- ter). The lightning flashes in the outer rainbands were much more than those in the inner rainbands, and less than 1% of flashes occurred within 100 km of the center. Each typhoon produced eyewall lightning outbreak during the periods of its intensifica- tion, usually several hours prior to its maximum intensity, indicating that lightning activity might be used as a proxy of intensi- fication of super typhoon. Little lightning occurred near the center after landing of the typhoon. super typhoon, lightning, WWLLN, the Northwest Pacific Citation: Pan L X, Qie X S, Liu D X, et al.

Occurrence of extreme water level events associated with tropical storms are often unpredicted and put coastal infrastructure and safety of coastal populations at risk. Hence, an improved understanding of the nature of storm surges and their components along the Vietnam coast is required. For example, a higher than expected extreme storm surge during Typhoon Kalmegi (2014) highlighted the lack of understanding on the characteristics of storm surges in Vietnam. Physical processes that influence the non-tidal water level associated with tropical storms can persist for up to 14 days, beginning 3–4 days prior to storm landfall and cease up to 10 days after the landfall of the typhoon. -

Fordebris Flow Triggering Characteristics and Occurrence Probability After Extreme Rainfalls: Case Study in the Chenyulan Watershed, Taiwan
forDebris flow triggering characteristics and occurrence probability after extreme rainfalls: case study in the Chenyulan watershed, Taiwan Jinn-Chyi Chen1, Jiang- Guo Jiang1, Wen-Shun Huang2, Yuan-Fan Tsai3 5 1Department of Environmental and Hazards-Resistant Design, Huafan University, Taipei 22301, Taiwan 2 Ecological Soil and Water Conservation Research Center, National Cheng Kung University, Tainan 70101, Taiwan 3Department of Social and Regional Development, National Taipei University of Education, Taipei 10671, Taiwan 10 Correspondence to: Jinn-Chyi Chen ([email protected]) ABSTRACT. Rainfall and other extreme events often trigger debris flows in Taiwan. This study examines the debris flow triggering characteristics and probability of debris flow occurrence after extreme rainfalls. The Chenyulan watershed, central Taiwan, which has suffered from the Chi-Chi 15 earthquake and extreme rainfalls, was selected as a study area. The rainfall index (RI) was used to analyze the return period and characteristics of debris flow occurrence after extreme rainfalls. The characteristics of debris flow occurrence included the variation in critical RI, threshold of RI for debris flow triggering, and recovery period, the time required for the lowered threshold to return to the original threshold. The variations in critical RI after extreme rainfall and the recovery period associated with RI 20 are presented. The critical RI threshold was reduced in the years following an extreme rainfall event. The reduction in RI as well as recovery period were influenced by the RI. Reduced RI values showed an increasing trend over time, and it gradually returned to the initial RI. The empirical relationship between the probability of debris flow occurrence (P) and corresponding return period (T) of the rainfall characteristics for areas affected by extreme rainfalls and affected by the Chi-Chi earthquake were 25 developed. -
Increasing Resilience to Natural Disasters with Cash-Based
VIETNAM | JUNE 2018 Increasing resilience to natural disasters with cash-based interventions LESSONS LEARNED AND BEST PRACTICES FROM CASH TRANSFER PROGRAMMING IN RESPONSE TO TYPHOON DAMREY IN VIETNAM Cover photo: Bui Thi Hau welcomes her 10‑year‑old daughter Bui Thi Hoang Ngan back from school as life slowly returns to normal after Typhoon Damrey caused widespread flooding in central Vietnam in November 2017. As the sole breadwinner of the family, Hau dreams of saving enough as a day laborer to send Hoang to university. But she would have had to take a high‑interest loan from a money lender to replenish the family’s rice stocks that were lost to the floodwaters. Catholic Relief Services, with the START Fund, rolled out an emergency project to directly support thousands like Hau with cash transfers. Hau was able to replace the rice they had lost in the storm.
