Summary

On March 19, 2008, an explosive eruption occurred at the summit of Kīlauea Volcano for the first time since 1924. This event marked the beginning of a continuous summit eruption that lasted until the 2018 Kīlauea lower East Rift Zone eruption (Neal and others, 2019). The March 19 explosive eruption excavated a crater approximately 35 meters wide and scattered volcanic tephra over a 30-hectare area. Only non-juvenile tephra was erupted on March 19 (Houghton and others, 2011). Two subsequent, minor explosions occurred on April 9 and April 16, 2008. These two explosions were dominated by lithic material though did also include some juvenile tephra. Tephra was produced continuously after the initial March 19 eruption but, excluding these [...]

Summary

On March 19, 2008, an explosive eruption occurred at the summit of Kīlauea Volcano for the first time since 1924. This event marked the beginning of a continuous summit eruption that lasted until the 2018 Kīlauea lower East Rift Zone eruption (Neal and others, 2019). The March 19 explosive eruption excavated a crater approximately 35 meters wide and scattered volcanic tephra over a 30-hectare area. Only non-juvenile tephra was erupted on March 19 (Houghton and others, 2011). Two subsequent, minor explosions occurred on April 9 and April 16, 2008. These two explosions were dominated by lithic material though did also include some juvenile tephra. Tephra was produced continuously after the initial March 19 eruption but, excluding these two April explosions, decreased substantially in the weeks that followed.

Following the onset of tephra production, the U.S. Geological Survey Hawaiian Volcano Observatory (HVO) collected tephra samples daily, each representing 24 hours. Tephra samples were collected at various locations within 300 meters southwest of the vent during normal trade winds, initially in aluminum pans and soon after in plastic buckets. Additional samples were donated to HVO by residents who live in Wood Valley (20 km from vent) and the South Point area (63 km from vent).

To prepare tephra for analysis, the bulk samples were homogenized and split using the cone-and-quartering technique. One quarter of the sample was archived and the remainder dry sieved at 2 mm (-1 φ). The <2 mm samples were distributed to U.S. Geological Survey laboratories for analysis. Efforts were made to select samples for analyses that were freshly deposited and not influenced by the effects of rain or wind.

This data release reports on analysis of samples collected between March 19 and April 16, 2008. Analyses include bulk sample digest chemistry, leachate chemistry, sulfur isotopes, sample mineralogy by X-ray diffraction, and particle size distributions by laser diffraction.

Purpose

This data release contains physicochemical analyses of volcanic ash samples from Kīlauea Volcano, Hawaiʻi, collected between March 19 and April 16, 2008. These data were obtained to provide insights into eruptive processes and support the assessment of volcanic hazards.
