Using ground crack and very low frequency measurements to map the location of the June 2007 Father’s Day dike, Kīlauea Volcano

Researchers successfully mapped the location of a dike intrusion during Kīlauea Volcano's June 2007 eruption using ground crack measurements and very low frequency (VLF) data. This study provides critical insights into volcanic processes, particularly the timing and extent of magma movement beneath the Earth's surface. The approach combined field observations with advanced geophysical techniques, enabling precise localization of the dike's path. Collaborations with USGS Hawaiian Volcano Observatory, National Park Service, and University of Hawai'i at Hilo enhanced data collection efforts, including aerial surveys and crack station measurements in Nāpau Crater. The findings contribute to better understanding volcanic hazards and improving eruption response strategies.
