Does power cut causing stuck in train problem count as an issue.
The area/volume of tunnels that have experienced strong quakes is very small compared with areas above ground where damage could occur. This might make where you would prefer to be a difficult comparison to make. Also rather than a simple above ground / tunnel it might be better to have several categories
1 Open field, no trees, no buildings, no landslip risk, no tsunami risk
2 Field some nearby trees, no buildings, no landslip risk, no tsunami risk
3 Wood, no buildings, no landslip risk, no tsunami risk
4 Tunnel, no items that could fall, no landslip risk, no tsunami risk
5 Hill some landslip risk, no buildings, no tsunami risk
6 Beach/lakeside, no buildings, no landslip risk
7 In/near building, no landslip risk, no tsunami risk
8 In/near building, some tsunami risk
Obviously could make lots more categories and above might not be right order. More people in 7 and 8 than in all other categories combined so a switch to 4th best place might be sensible?
