The fires– which were predicted and predicted by a modern seismologist– resulted in the very first lessons in earthquake security for schoolchildren in Japan after the earthquake. More recently, the history of earthquake-related fires in Japan has actually led to seismic shutoff valves being positioned on gas meters throughout the country.
The hazard of earthquake blazes has not vanished. The authors state locations with strong seismic shaking and a large inventory of wood-framed structures– the U.S. West Coast including Los Angeles, San Francisco and Seattle, Japan and parts of New Zealand– should highlight fire prevention and response as part of their earthquake mitigation strategies.

The scientists discovered that less than 5% of the literature discussed the 1923 Kantō earthquake goes over the fire in detail, regardless of the fact that fire storms triggered most of damage and deaths compared to extreme ground shaking and liquefaction. Current calculations put the fire losses at an overall of practically ¥ 1.5 billion. For comparison, Japans overall nationwide spending plan for 1923 was ¥ 1.37 billion.
For these factors, the authors state, the event ought to be referred to as Kantō Daikasai or the Great Kantō Fire Disaster rather of the more common name of Kantō Daishinsai or Great Kantō Earthquake Disaster.
Foreseen and Foretold
The blaze following the earthquake had actually been envisioned in 1905 by Imamura Akitsune, an assistant teacher of seismology at Tokyo Imperial University. He thought a seismic gap in the area and recommended a big earthquake was due. He cautioned that people of Tokyo would have no location to shelter from fires activated by such an earthquake. He recommended procedures such as abolishing kerosene lanterns and producing obstacles in between new structures to minimize the risk.
Imamuras cautions, however, were ridiculed by Japans leading seismologist at the time, Ōmori Fusakichi, a senior coworker, who did not think in the seismic gap theory. Ōmori likewise thought earthquakes rarely happened in windy or stormy weather, so there would not be adequate wind to cause fires to spread.
The Kantō earthquake took place two minutes to noon on 1 September, when lots of people were lighting conventional kamado cooking ranges and shichirin and hibachi grills to cook a midday meal. Ground shaking fell a number of these, and within the very first hour after the earthquake there were one hundred fires across the city– “a city largely constructed up of cheek-by-jowl light wood and paper real estate,” stated Charles Scawthorn, a scientist at the Pacific Earthquake Engineering Research Center, University of California at Berkeley.
” Under common scenarios, the Tokyo fire department would not have had the ability to address all these fires, but intensifying the circumstance were hundreds of breaks in the water pipe, so that firefighters were mostly powerless,” stated Scawthorn, co-author of “Fire Following Earthquake.”
The fires merged up until some were so large that they produced their own high winds, becoming fire tries or cyclones that consumed whatever in their course.
In the BSSA paper, Tomoaki Nishino of the Disaster Prevention Research Institute at Kyoto University assisted to explore the big image of the fires including wind-blown fire plumes and design the spread of the fires, specifically their relationship to wind instructions and velocity. Nishino likewise took a look at how a city fire may spread in Kyoto City after a possible magnitude 7.5 situation earthquake along the Hanaore fault.
” Large fires after an earthquake depend not only on the strength of the shaking, but on other conditions like the weather condition and constructed environment,” Nishino discussed. “If the area consists of numerous fireproof structures, or a low density of buildings, the conflagrations would not happen.”
” The collection of those conditions is less regular than strong shaking, so the terrible local impact of fires following earthquakes is less frequent compared to that of earth-shaking,” he added. “But there can be a time when the number of synchronised fires overwhelms firefighting capabilities.”
History Lessons
The BSSA authors likewise go over the extensive impact of the conflagration on metropolitan planning, politics, and education in Japan in the years following the damage. Janet Borland, a historian at the International Christian University in Tokyo, became thinking about studying the Kantō earthquake and fire after experiencing the 1995 Hanshin-Awaji or Kobe earthquake as an exchange student. She is the author of “Earthquake Children: Building Resilience from the Ruins of Tokyo,” detailing the effects of the 1923 occasion on children and education.
Borland has collected more than 2,000 firsthand accounts of the occasion composed and shown by kids. “They give us a really important insight into the specific experiences of this catastrophic occasion in Japanese history, all across Tokyo,” she said, “of children who experienced fires, who enjoyed moms and dads drown in the Sumida River, or who were on the borders of the city and saw all these refugees leaving.”
Imamura “invested so much as a seismologist in public education” after 1923, including pressing for the really first earthquake safety lesson in the Japanese school curriculum, Borland stated. “He convinced the Ministry of Education authorities, Were an earthquake nation, we need to teach our children what to do when an earthquake strikes.”.
Charles Schencking, a historian at the University of Hong Kong, started studying the Kantō event by taking a look at “how the elites translated the catastrophe, how they tried to use the disaster to not only restore the capital however to rebuild the country on an ideological or social level,” he stated.
Schencking, author of “The Great Kantō Earthquake and the Chimera of National Reconstruction in Japan,” likewise was drawn to the range of stories about how people survived those dreadful days.
” The harrowing individual accounts and the emotiveness of the product just drew me in and assisted me become a different sort of historian,” he said. “The broad series of methods you might require to learn about society by studying a catastrophe and the action that follows is to me tremendously satisfying.”.
” Imamura predicted and anticipated– science can caution, but economics, politics, and resources need to be activated if a caution is to have any efficiency,” Scawthorn said.

The fires following the 1923 Kantō earthquake killed 90% of the victims, making it one of historys most dangerous natural catastrophes. A current paper highlights the significance of fire avoidance in earthquake-prone locations and underscores the interaction between socio-economic reactions and clinical predictions.
The 1923 Kantō earthquake in Tokyo led to fires accountable for 90% of the 105,000 casualties. This tragedy, detailed in a brand-new paper in the Bulletin of the Seismological Society of America, provides lessons for present earthquake scientists and metropolitan organizers.
Fires that raged in the days following the September 1, 1923, magnitude 7.9 Kantō earthquake killed approximately 90% of the 105,000 people who died around Tokyo, making it one of the most dangerous natural catastrophes in history– similar to the number of people eliminated worldwide War II atomic bombing of Hiroshima.
The story of the blaze, not popular outside of Japan, holds crucial lessons for earthquake scientists, emergency response teams, and city planners, according to a brand-new paper published in the Bulletin of the Seismological Society of America. The paper is part of an approaching BSSA unique concern on the 1923 Kantō earthquake.
