View is from a damaged section of the Crater Rim Drive above Waldron Ledge toward the south. This section of the Crater Rim Drive (paved surface visible in lower left and right center) was abandoned as a result of the earthquake damage. The top of Pu`u Pua`i cinder and spatter cone is visible left of tree.>
A magnitude 6.6 earthquake along the Kaoiki fault zone (on the southeast flank of Mauna Loa) on November 16, 1983, triggered many landslides and rockfalls from the walls of Kilauea Caldera. Parts of the Crater Rim Drive above Waldron Ledge slid into the caldera, and heavy damage was caused to other roads in Hawai`i Volcanoes National Park where they cross or parallel the many faults of Kilauea Caldera. The Hawaiian Volcano Observatory also suffered damage from the earthquake.
