Geology in Vanuatu

      These islands are all volcanic or coral.  It is pretty hard stuff.  When they excavate for a new project, they never build any retaining walls.  The structure of the ground is enough.  Currently, they are digging out a big hill of land.  Here it is more than a hill.  The part that is so interesting to us is that the earth strata are so evident.  And - the shifting of the earth's crust when there have been earthquakes.  See what we mean!
