Hard but not impossible.Random thought: How is he biking with one hand?
As someone who has been in a similar magnitude earthquake (8.5), it’s like walking in a subway train. Most people can walk in it, but if you are knocked off balance, are injured, or just aren’t ready for it, it can be difficult to recover from once you fall. It also depends on the land you’re on. Some parts just shake more than others.I lived through an 8.8 earthquake and I could walk let alone stand. Do all Japanese have weak legs or was that just the case on the 20s?
