  36. 36. It was not until this year that I could at lastset foot on the now-deserted coast.Drawing maps brings back memorise of those places.
  37. 37. Movement of the Earths crust in the Earthuake
  38. 38. A survey by GSI(Geospatial Information Authority of Japan) has revealed that land in the Tohoku region moved to the south-east in the earthquake. Ishinomaki City in Miyagi Prefecture moved up to 5.3meters.Geospatial Information Authority of Japan(GSI)http://www.gsi.go.jp/chibankansi/chikakukansi_tohoku2.html”平成23年(2011年)東北地方太平洋沖地震に伴う地殻変動について”国土地理院 平成23年3月19日発表
  39. 39. I compared data taken on my handheld GPSbefore the earthquake to that taken after the earthquake to determine if the earths crust had moved. The GPS model used was the same in both cases.
  40. 40. I compared data two places. 6km-long Breakwater Circular stage on the beach© OpenStreetMap contributors, CC BY-SA
  41. 41. Comparison at the southern tip of the Breakwater 4m May 2012 logs Comparison of GPS logs taken before and after the earthquake show an eastward movement of approximately 4m. Sep 2008 logsRestroom buildings Restroom buildings Logs of taken from the restroom buildings also appear to show movement.
  42. 42. Comparison at the Circular stage on the beach3m Comparison of GPS logs taken before and after the earthquake show an eastward movement of approximately 3m. 3m
  43. 43. Although comparison of data taken by a commercial GPSand the handheld GPS showed the datafrom the latter to be less accurate,I realised it was possible toconfirm the movement of the earths crustwith a handheld GPS under the right circumstances.
  44. 44. Chapter 4Nuclear Disaster
  45. 45. A nuclear accident followed the earthquake and tsunami.Many mappers mapped the Fukushima nuclear power plant.
  46. 46. Following the accident citizens were not made aware of the distribution of radiation. After the accident, measurement and release of radiation data by the government was too slow.Photo : After the disaster / Iwaki city,Fukushima
  47. 47. About one month after the accidentI decided to map the radiation levels in Fukushima as a private citizen. Radiation Mapping
  48. 48. First,I set several waypoints on my GPSand recorded the levels with a Geiger Counter.

  58. 58. Which part of this map draws your attention?© OpenStreetMap contributors, CC BY-SA
  59. 59. Which part of this map draws your attention? Yonezawa CityMany of you would answer “The red area”.The area that draws my attention is this blue area over Yonezawa.To my relief, this showed that area within 20km of Fukushima Citywas not contaminated in the accident.The focus of society has been on the hotspots.However, I think we should focus more on which areas are safe.

  61. 61. Use of OSM in Radiation Level MapWeb mapping sites such as Google and Yahooonly show detailed maps for the areas in blue.The red areas signify the evacuation zones Fukushima I(~August,2012), which were of great concern Nuclear Power Plantto citizens. 20km evacuation zoneHowever, there were almost no detailed mapof these areas.Even now, these are insufficient detailed mapsof this area.I believe OpenStreetMap can be used toeffectively create detailed maps for thesered areas. © OpenStreetMap contributors, CC BY-SA
  62. 62. Now, the number of measurement points has increased and the governmentis releasing substantial amounts of reliable data.We are now focusing on even more precise data. © OpenStreetMap contributors, CC BY-SA
  63. 63. In order to gather this precise data,we have been measuring the radiation on foot using new equipment with data-saving functions.© OpenStreetMap contributors, CC BY-SA

  66. 66. But the necessity of providing data for OSMmade me start mapping the coast again.
  67. 67. Last year, When I saw aerial images from Bing taken after the earthquake,I knew exactly which areas I had to go to.I at last made my way to those places this year. Bing coverage analyser showing Fukushima area. http://ant.dev.openstreetmap.org/bingimageanalyzer/?lat=-12&zoom=1
