Detailed Description

A USGS Hawaiian Volcano Observatory geologist monitored the advance of an ‘A‘ā lava flow on April 6 during the 1984 Mauna Loa eruption. This flow was about 4 m (13 ft) high and advancing at a rate of 50 m (55 yards) per hour. Lava reached within 6 km (4 mi) of Hilo city limits before the 22-day-long eruption ended on April 15.
