  <dc:description>&lt;p&gt;The determination of in situ stresses along deep vertical profiles was declared a key issue for two scientific deep drilling projects:&lt;/p&gt;&lt;ul class="alpha-lower"&gt;&lt;li&gt;&lt;p&gt;the German Continental Deep Drilling Project (KTB) situated in northeast Bavaria in an area of complex variscian thrust tectonics and&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;the CAJON PASS Project, located only about 4 km from the San Andreas Fault Zone In southern California.&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;In the KTB project 7 successful hydrofrac stress measurements could be completed in a 4 km deep pilot hole between 0.8 to 3.0 km. At the Cajon Pass site a series of 23 hydrofrac stress measurements was performed in 2 wells between 0.9 to 3.5 km.&lt;/p&gt;</dc:description>
