Japan: the next big quake
The government’s figures put the odds of a magnitude 8.0-plus Nankai Trough earthquake at 50 per cent in the next 20 years, 70 per cent in the next 30 years and 90 per cent in the next half century.

In the worst case of a magnitude 9.0 quake, close to land, Tokyo puts losses at ¥220tn ($2tn) for the first year alone. The amount is hard to imagine: 40 per cent of Japan’s GDP, equal to the market capitalisation of Apple, Microsoft, Berkshire Hathaway, ExxonMobil and Facebook combined. Around three-quarters of that is property damage, most of it privately owned, and the rest is lost economic activity.

The worst fatality rates in Tohoku towns were about 10 per cent, whereas historic records suggest fatality rates of half or two-thirds for unprepared fishing villages after a similar tsunami in 1896. In total, 97 per cent of people in the Tohoku inundation area survived.

That reflects the benefits of engineering, early warning and evacuation.

WindSim - Terrain - Third party formats
The ESRI Shapefile .shp format containing contours must be filtered in order to only contain the contour line data before converting the data to the .gws format. The filtering can be done with the program Arcv2CAD converting .shp files into .dxf files. As a second step the .dxf must be converted to .gws as described above. The program Arcv2CAD is available at http://www.guthcad.com.au
