Flood aftermath linked to post-traumatic stress, study shows "The study found the strongest predictors of depression were prior mental health, repair time and self-efficacy (confidence in their ability to cope)." "Survivors said they were more confident they could cope with difficult circumstances in the future and they had found the experience had strengthened their relationships and social networks."

Volcanic eruption in Japan

This morning there was a volcanic eruption on Kuchinoerabu island where about 110-150 people live. It is located about 1,111 km away from Tsukuba (same distance as e.g. Maastricht -Barcelona/Rome/Warsaw).

The plume gases have come up to 9,000 m high, a significant height interrupting the flight plans of several airlines. While the island is located a mere 15 km from the larger Yakushima, popular among tourists, it still takes an hour to get there by boat. Reports are a ferry from Yakushima picked up around 100 people already and evacuated them.

Previous eruptions of the Shindake (New Peak, 新岳) include last year, August 4th 2014, with no casualties. Among other known eruptions (in 1980, 1976, 1974, 1973, 1972, 1968-69, 1966, 1945, 1933-34) only this last one in 1933 led to 8 deaths.

WWF7 newspaper article on ICHARM's concluding session

The Japanese drainage system newspaper (Gesuido shimbun, 下水道新聞) published an article (22nd of April) about ICHARM's activities during the WWF7 last month. It shows a picture of the concluding session we organized on the final day with ICHARM's director Prof. Koike sitting on the left.

The approximate translation is as follows (verified by an anonymous Japanese ICHARM employee): 

ICHARM discussed the proposed roadmap to disaster prevention and mitigation of water-related disasters

On the 17th of April the International Centre for Water Hazard and Risk Management (ICHARM, with as Director Toshio Koike, Professor at the University of Tokyo Graduate School) reported the summary of the seven sessions on water-related disasters where discussion has taken place during the 7th World Water Forum as Thematic Process, corresponding to the theme of "Adapting to change: Monitoring risk and uncertainty for resilience and disaster preparedness." Views were exchanged on the Implementation Roadmap, a plan that contains the future goals and efforts on this theme.

The proposed roadmap covers the following goals and requires water-related stakeholders around the world to voluntarily pursue related efforts:

▽ understanding of water-related disaster risks

▽ governance strengthening for risk management

▽ investment in reduction of water-related disaster risks for disaster mitigation

▽increased "building-back better" in disaster rebuilding, rehabilitation and reconstruction plans

The roadmap is accompanied with specific actions so as to periodically consolidate such efforts and share information. 

Director Koike, who participated in the said Thematic Process, said “We will review the progress of each of the efforts at ICHARM and actively share such information”.

 The roadmap will be announced in mid-May.

Published Paper

The journal Water Policy has published an article by Sangeun Lee and myself titled "Assessing the vulnerability of different age groups regarding flood fatalities: case study in the Philippines". It is still in press, as uncorrected proof.

Abstract
This study aimed to identify age groups vulnerable to flood fatalities and quantify their vulnerability by means of statistical methods. First, the study obtained data of 122 victims directly resulting from five flood disasters in the Philippines over the period 2010–2013 which was used to compare the number of flood fatalities in each age group with the population numbers. The chi-square goodness-of-fit test shows that only one age group, people aged less than and up to 70, was vulnerable to flood fatalities. Vulnerabilities of people aged less than and up to 70 and over 70, respectively, were quantified in terms of mortality, i.e., the ratio of flood fatalities and affected people. This study obtained two lognormal distribution curves moderately describing histograms built with samples on the mortality of the two age groups. Based on probabilistic parameters of the selected lognormal distribution curves, the study concludes that people aged less than and up to 70 have more than three times the vulnerability to the risk of flood fatality than people aged over 70. It is also suggested that the age dependency ratio, which is widely used to consider demographic vulnerability in flood vulnerability studies, should not be applied to the Philippines.
