| Lava production from these "2,900-m vents" decreased from less than 100,000 m3 per hour on April 9 to about 20,000 m3 on April 13, which was the last full day of eruption. Active lava flows extended less than 2 km from the vents. Note two geologists for scale in lower right (in green flight suits). Mauna Loa summit in upper left. |
