Ok, let me try to explain further for you. The image below is taken from the following link.

I guarantee you that to meet the modern seismic requirements, any new tunnel MUST be deeper than the liquifaction zone underneath the river. As you can see, that puts it significantly deeper than the existing tunnel.
Any new tunnel is going to be bored. They will not be allowed to dredge and submerge a tunnel similar to the original, and even if they could, it would not be seismically stable in liquifiable soils.
