Kanto Earthquake, Tokyo, 1923 Causes and Effects

Extracts from this document...

Introduction

4.10.01 Kanto Earthquake, Tokyo, 1923 Causes and Effects: Japan is situated on the Continental Eurasian Plate. Both the Philippines and Pacific Oceanic Plates are constantly being subducted under the Eurasian Plate creating a Destructive Plate Margin. This area is part of the Pacific 'Ring of Fire' which is renown for its earthquake and volcanic activity. Previous to the Kanto earthquake of 1923 Tokyo had not been hit since 1853. In some areas this may have caused the population to become complacent about safety issues, but as Japan is in such a tectonically unstable area they are in a constant state of readiness. The Kanto earthquake measured 8.2 on the Richter Scale. Its epicentre was situated in the Sagami Bay, 80km south of Tokyo. However, it took only 44 seconds for the first shockwaves to hit Tokyo. In total the earthquake measured as the most disastrous in Japanese history. The total dead amounted to around 140'000, 100'000 in Tokyo and 40'000 in nearby Yokohama. ...read more.

This all resulted in a total of 700'000 homes, 9000 factories and roughly 66% of the city being burnt to the ground. Responses: Almost straight after the earthquake damage had been repaired the government set about plans to educate the population about earthquakes and so hopefully save many lives if one were to happen again. o September 1st was designated 'Disaster Day, with the whole city practicing drills and simulated earthquakes. o Schools were made to practice drills regularly in order to educate the young of the city how to best survive. o People were advised to switch off ovens and stoves so as not to repeat the terrible explosions caused last time thought gas explosions. They were also told not to store things on high shelves, as falling objects are one of the largest killers during an earthquake. The Japanese realised from past experience and from studying other large earthquakes that the main impact was not the greatest killer, but the aftermath, and so they set up the following in an attempt to save many lives after the next earthquake strikes: o Emergency water tanks and generators were installed in each district incase of power loss or water contamination. ...read more.

Conclusion

o Extra walls were also introduced both inside and out to improve strength and flexibility of buildings. During the Kanto earthquake of 1923, 66% of the city was burnt to the ground. Fire was the main destructive force of the whole earthquake. For this reason when Tokyo was rebuilt wooden building materials were avoided and open spaces were created to act as firebreaks, preventing the fire spreading any further. Fireproof buildings such as the Shirahige-Higashi apartment were also constructed for similar effect. 543 hectares of housing were strengthened and fireproofed and further areas were demolished to again act as firebreaks within the city. One of the main reasons for the huge death toll in the Kanto earthquake was because the population were taken thoroughly by surprise. Measures were taken to improve earthquake prediction in the meetings that followed the disaster. Instruments were installed to measure the Earth's movements. The next earthquake being predicted for 2020. City authorities also promised that next time, the public will be given at least a few hours in order to prepare themselves for the initial impact. ...read more.
