Hualalai has three rift zones, recognized by prominent cinder and spatter cones that trend northwest, north, and south-southeast from a point about 5 km east of its summit. Geologists have grouped lava flows exposed on the surface of Hualalai according to the following ages:
-
Lava flows < 10,000 years old cover about 5 percent of the volcano
-
Lava flows 5,000-10,000 years old cover about 15 percent of the volcano
-
Lava flows 3,000-5,000 years old cover about 25 percent of the volcano
-
Lava flows 1,500-3,000 years old cover about 38 percent of the volcano
-
Lava flows 750-1,500 years old cover about 8 percent of the volcano
-
One map unit 200-750 years old covers about 3 percent of the volcano
-
Vent deposits and lava flows of the historic A.D. 1800-1801 eruption cover about 6 percent of the volcano
