Lava tubes are everywhere. Each flow makes more of them, and that's been going on for half a million years. However, many are just holes in the ground and not very interesting - particularly the ones that people can get inside and wreck. Some are used as open sewers or dump sites. Very few are interesting like large mainland cave systems. And, well, you aren't supposed to go into them anyway.
