- It is well known that the principal tectonic stress directions in
an area can be determined from earthquake fault plane solutions. Recently, a
method has been developed by which these directions can also be determined
from measurements of the orientation of joints in an area. In the present paper,
a comparison is attempted between the directions calculated by the two methods
for the Alpine region. It is shown that in Switzerland the agreement between
the two methods is good
