Earthquakes Japan 2015

This is an overview of all the earthquakes in Japan in 2014, sorted per magnitude and shindo (震度, shaking intensity). This data was generated by using the Japan Meteorological Agency database.

The most earthquakes in a single category were shindo 1 and magnitude 3-3.9.
Shindo 1 earthquakes ranged from magnitude 0 to 6.9.
Shindo 2 earthquakes ranged from magnitude 1 to 6.9.
Shindo 3 earthquakes ranged from magnitude 1 to 6.9.
Shindo 4 earthquakes ranged from magnitude 3 to 7.9.
Shindo 5- earthquakes ranged from magnitude 5 to 5.9.
The Shindo 5+ earthquake fell into magnitude 5 to 8.9.

Japan:

556 bridges found to have bad supports:The devices are supposed to keep the bridges from collapsing during major earthquakes.

USA:

Key elements of digital disaster communications demystified: Messages describing hazard impacts and emphasizing cohesion among users generated the most "retweets". Other elements encouraging retransmission include the number of users in an agency's network and the inclusion of an agreed-upon hashtag. "Shorter messages are not necessarily simpler to write," said lead author Jeannette Sutton, director of the University of Kentucky's Risk & Disaster Communication Center. "We have decades of research on longer warning messages and practically none on short messages.

Texas tornadoes: Eleven killed in Dallas area: Eleven people have been killed in tornadoes in Texas, police say, with heavy rain and snow causing deaths and disruption in a number of other states. Further north, six people died in two incidents when cars drove into flooded roads in Missouri. Another driver was found dead in his car in a creek. Three adults and two children also drowned in southern Illinois when their vehicle was swept away.

Heavy floods in parts of South America (Dutch):Nearly 150,000 people in Paraguay, Argentina and Uruguay were forced to leave their houses due to floods. Most heavily affected was Paraguay (130,000 people), where a state of emergency has been declared and the president has already dedicated over 3 million euro as response funds. Over 125,000 people have lost power to their homes. Five people have died (4 from falling trees and one from electrocution).

According to the methods used in my latest published paper, these victims would not technically be counted as flood victims, as in that study, we excluded cases where victims died of causes unrelated to floods [such as being crushed by trees, falling from roofs, being blown off the road, or receiving electric shocks, and we found that 38% (122 victims) of the data relating to the 325 victims consisted of causes of death such as drowning (hypothermia or asphyxiation), heart attacks, or physical trauma during evacuation].

Vegetarian and 'healthy' diets are more harmful to the environment: "Eating lettuce is over three times worse in greenhouse gas emissions than eating bacon," said Paul Fischbeck, professor of social and decisions sciences and engineering and public policy. "Lots of common vegetables require more resources per calorie than you would think. Eggplant, celery and cucumbers look particularly bad when compared to pork or chicken." eating the recommended "healthier" foods -- a mix of fruits, vegetables, dairy and seafood -- increased the environmental impact in all three categories: Energy use went up by 38 percent, water use by 10 percent and GHG emissions by 6 percent.

Vulnerable People:

Child poverty could cost Japan $33 billion: The group predicted how their job prospects and lifetime earnings could change in 2 scenarios. One is that the government offers them assistance to go to high schools or colleges. The other is that the government doesn't take any action. The organization says the government's inaction would reduce the number of regular employees by 9,000 and leave 4,000 unemployed. It notes that this could result in a loss of about 24 billion dollars in their income, compared with when the government took action.

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 now available online in final form (a previous version was available in May). Although this publication is not open access, full PDF copies are available upon request.

Abstract (adapted to adjust html codes to proper screen coding)
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.

UNESCO ENHANS project meeting

ENHANCING NATURAL HAZARDS RESILIENCE IN SOUTH AMERICA

At this meeting Masahiko Murase from ICHARM explained the research and education activities at ICHARM, and Karina Vink showed three models used for different project: BTOP, IFAS and RRI. 

A program specialist of UNESCO requested more technical requirements of an IFAS training for the four target countries of the ENHANS project. The ENHANS project currently has as target countries: Ecuador, Chili, Peru, Uruguay. The first target for IFAS training would be Chili/Peru, possibly simultaneously as the target areas in these countries border each other (North Chili, South Peru). As training period May was suggested. 

The ENHANS meeting in Montevideo was successful as multiple parties expressed an interest in IFAS training and ICHARM models. As a next step a governmental request for IFAS training would aid in arranging the necessary required administrative steps and financing surrounding the organization of IFAS trainings abroad. ICHARM will continue to support and prepare for IFAS training in the ENHANS target countries if so requested.
