The majority of Hawaii's telescopes are on Mauna Kea rather than Mauna Loa because Mauna Loa is still active and therefore dangerous. However, with all of Mauna Kea's available sites in use and the Hawaiian government unwilling to open up more, AMiBA ended up on Mauna Loa.
由於毛納洛峰是存在爆發危險的活火山，因此多數望遠鏡都集中在鄰近的毛納基峰；近幾年毛納基峰基地已趨飽和，夏威夷政府不願再開放，AMiBA 只好轉戰毛納洛峰。
