Pahoehoe lava is smooth and ropy while Aa lava is blocky and hard. Lava flows normally follow the topography, sinking into depressions and valleys and flowing down the volcano. Lava flows will bury roads, farmlands and other forms of personal property. [1] This lava could destroy homes, cars, and lives standing in the way. [2]
A hyperconcentrated-flow lahar can leave even frail huts standing, while at the same time burying them in mud, [8] which can harden to near-concrete hardness. A lahar's viscosity decreases the longer it flows and can be further thinned by rain, producing a quicksand -like mixture that can remain fluidized for weeks and complicate search and rescue.
Only a few percents of this area has been covered by lava in the past 10,000 years. Zone 9 - Kohala Volcano, which last erupted over 60,000 years ago. Lava Flow Hazard map of Haleakala. The Maui Hazard Zone numbers are a different scale from the island of Hawaiʻi's map. The lava flow hazard zones on Maui use a different scale.

Effusive basalt lava flows cool to either of two forms, ʻaʻā or pāhoehoe. [8] This type of lava flow builds shield volcanoes, which are, for example, numerous in Hawaii, [9] and is how the island was and currently is being formed.
