Summary:

As part of the Hawaii Scientific Drilling Project, Kahi Puka Well 1 penetrated about 275 m of Mauna Loa basalts overlying a sequence of Mauna Kea flow units. A borehole televiewer (BHTV) was run in most of the well in order to obtain magnetically oriented acoustic images of the borehole wall. We focus on the detailed analysis of fractures that intersect the well and interpret the results in terms of the growth and evolution of the Hawaii Island. The observed rotation in the orientations of the two predominant fracture subsets may be attributed to changes in the configurations of volcanic sources during shield building and to the structural interference of adjacent volcanoes.
