The dormant Thrihnukagigur Volcano last erupted over 4000 years ago. The volcano's name would be directly translated to English as "Three Peaks Crater" and is located about 20 km southeast of Reykjavik. In June of 2012, UNAVCO provided support to Dr. LaFemina for a TLS survey campaign around Thrihnukagigur. This was a repeat scan of regions first covered in 2008. A Leica C10 scanner was used to scan the inner chamber, shaft and surrounding area above the Thrihnukagigur Volcano. Over the course of 7 days, 18 scan positions were occupied and over 500 million points collected. In comparison, previous surveys of the magma chamber using land-surveying equipment produced only 1200 points.
