Many large and important telescopes are located on top of Mauna Kea on Hawaii. This is a great location for many reasons: it's tall enough to be above the weather, an inversion layer at night keeps the atmosphere clear and dry, etc. But right next to Mauna Kea is an equally tall mountain Mauna Loa. Although there are some instruments on Mauna Loa (a NOAA station) there aren't major telescopes. Why? What makes Mauna Kea a better location?

Mauna Loa is an active volcano. The last eruption was in 1984.

  • $\begingroup$ @NoahSnyder Given the cost of the facilities very small threats are worth avoiding. These things don't have to be likely to be problem for getting funding to build there. $\endgroup$ Jul 12, 2013 at 2:56

    $\begingroup$ Since it is an active volcano, it is also a very active earthquake area. $\endgroup$ Jul 12, 2013 at 3:07
