AB: Although its more recently active neighbor, Kilauea, has an extensive network of GPS stations, the coverage for Mauna Loa, earth's largest volcano, was relatively sparse. In response to the onset of recent Mauna Loa reinflation, we have installed 11 more Continuous GPS receivers to provide denser coverage of the summit region and two flanking rift zones. This network should image future volcanic events on Mauna Loa and give new insights into structural and dynamic controls. Additionally, we have implemented a near real-time processing approach using the PAGES GPS software so that deformation events can be quickly identified for more detailed investigation. Preliminary solutions from this processing stream suggest that atmospheric heterogeneities present the most significant source of errors that must be assessed and mitigated in order to resolve subtle or transient details of these events.
