Deformation Studies
Deformation Monitoring Projects
Francine Coloma spent several years at the Hawaiian Volcano Observatory with the Deformation Monitoring Team using GPS, survey leveling, tilt, and EDM, to monitor Kilauea and Mauna Loa's changing shape resulting from underground magma movement. Coloma also provided data management assistance by making sure the data from all the instruments was received, processed, and archived. In 2000, HVO designated Coloma to be the on-site manager for installing three borehole strainmeters or "dilatometers" on Mauna Loa volcano at a depth of about 300 feet, which required a specialized mobile drill rig. Another "by-product" of the drilling was the core samples removed from the hole.

Integrated Data Archive
Ralph Krug of Germany was hired to develop state-of-the-art software that allows the scientific staff of HVO to manipulate and interpret ground deformation and other data in new and exciting ways. With his demonstrated ability to develop innovative software, he created an integrated data management platform that enables HVO staff to compile and analyze data from the diverse array of techniques applied at HVO. His work under the Cooperative Agreement was to build and fine-tune a massive archival plus real-time data base that allows HVO scientists to call up information on seismic amplitude, tilt, GPS, strain, and sulphur dioxide emissions, all on a common time base. Scientists using the system can click on a section of a map or select a station by name, and can combine different types of data and view it on graphs. This allows the scientists to see the big picture, and to correlate changes in conditions detected by a broad range of instruments. This continuous data collection is also compared to results from campaign-style data collection, such as the GPS campaign pictured below. Ricky Herd joined HVO's deformation team from 2004 - 2006, assisting with the expansion of the network.
