you could try to do a Delaunay triangulation of your points to get a surface representing the ground. You might have to project your points onto a plane since normally Delaunay triangulation works only in 2d AFAIK. Once you have the ground, you can define additional points at the edges of the volume you want to consider, define lines and surfaces and finally the volume. Then you can do a mesh3D.
For details, consult the gmsh documentation and ask the gmsh mailing list.

Betreff: RE: [Gmsh] Important question for my Thesis
For my tsunami simulation I need to generate a depth-dependent mesh with coarse resolution at deep water and high resolution at coast and land (for inundation).
The topography data is a text file containing the depth for each point in the domain. Is it possible to import this data and give gmsh the command to perform a depth-depended triangle size?
Thanks in advance,
