Abstract
Animal-related consequences were not anticipated in disaster preparedness planning in Japan at the time of its massive earthquakes in 2011. Evacuation failure was quite common due to pet ownership in this disaster. Public attention to the welfare of affected animals in this disaster triggered an awareness of the importance of caring for their needs. However, research on human behavior toward pets or effect of pets on human during disasters remains sparse. In this study, post-traumatic stress disorder (PTSD) scores among pet-owners and non-pet owners in Japan's 2011 earthquake disaster were compared, and attitudes toward pets were evaluated. A questionnaire was distributed to attendees, and interviews were performed at an annual animal welfare event. The Japanese-language version of the revised Impact of Event Scale was used to evaluate PTSD from the disaster. PTSD scores were higher in pet-owners compared to non-pet owners immediately after the earthquakes, but were lower in pet-owners compared to non-pet owners 4.4 years following the disaster. Most people opined that pets should evacuate with people, although less than half of non-pet owners agreed with having animals co-located at evacuation centers. In order to enhance safety and security of both humans and animals at evacuation centers, it is important to proactively address animal issues in disaster preparedness planning. Although pets were regarded by some as adverse risk factors for human health and safety during a disaster; this study instead suggests that pets may play an important positive and protective role for disaster victims.
Highlights
The Great East Japan Earthquakes of March 11th, 2011 were an unprecedented disaster that caused immense damage in a broad area covering approximately 1 million km2 (∼200 km from east to west in width and ∼500 km from north to south in length) along the coastline of northern Japan
Pet ownership did not have an association with post-traumatic stress disorder (PTSD) score 1 month after the disaster (p = 0.337)
When pet type was disaggregated to specific animal species, dog owners had significantly higher PTSD scores than non-pet owners (p = 0.025) (Table 3)
Summary
The Great East Japan Earthquakes of March 11th, 2011 were an unprecedented disaster that caused immense damage in a broad area covering approximately 1 million km (∼200 km from east to west in width and ∼500 km from north to south in length) along the coastline of northern Japan. The worst affected areas were the Fukushima, Miyagi and Iwate prefectures, where more than 18,300 people were killed or missing. Companion animals fell victim to the disaster, contributing to the deaths of an estimated 16,000 dogs and more than 23,000 cats. The majority of these deaths were in the Miyagi prefecture, accounting for more than 60% of the deaths in dogs and ∼90% in cats.
