which is bigger kīlauea and mauna loa or mount everest
Mauna Loa Mauna Loa is the largest subaerial and second largest overall volcano in the world (behind Tamu Massif),[15] covering a land area of 5,271 km2 (2,035 sq mi) and spans a maximum width of 120 km (75 mi).[2] Consisting of approximately 65,000 to 80,000 km3 (15,600 to 19,200 cu mi) of solid rock,[16] it makes up more than half of the surface area of the island of Hawaiʻi. Combining the volcano's extensive submarine flanks (5,000 m (16,400 ft) to the sea floor) and 4,170 m (13,680 ft) subaerial height, Mauna Loa rises 9,170 m (30,085 ft) from base to summit,[2][17] greater than the 8,848 m or 29,029 ft[18] elevation of Mount Everest from sea level to its summit. In addition, much of the mountain is invisible even underwater: its mass depresses the crust beneath it by another 8 km (5 mi), in the shape of an inverse mountain,[19] meaning the total height of Mauna Loa from the start of its eruptive history is about 17,170 m (56,000 ft).[20]
Kīlauea A prominent structure on Kīlauea's southern flank is the Hilina fault system, a highly active fault moving vertically an average of 2 to 20 mm (0.1 to 0.8 in) per year along the system. Its physiographic province is 500 m (1,640 ft) deep, but it is unknown if it is a shallow listric fault or if it penetrates to the very base of the volcano.[3] A number of cinder cones, satellite shields, lava tubes, and other eruptive structures also dot the volcano, evidence of its recent activity.[20] Kīlauea has some interactions with Mauna Loa, its larger neighbor and only other recently active volcano on the island; interspersed lava flows and ash deposits belonging to its neighbor have been found on its flanks, and some of Mauna Loa's flows are, in turn, blanketed in Kīlauea tephra. In particular, the saddle between the two volcanoes is currently depressed, and is likely to fill over in the future.[17]
Mauna Kea Mauna Kea (/ˌmɔːnə ˈkeɪ.ə/ or /ˌmaʊnə ˈkeɪ.ə/, Hawaiian: [ˈmɐwnə ˈkɛjə]) is a dormant volcano on the island of Hawaii. Its peak is 4,207 m (13,802 ft) above sea level, making it the highest point in the state of Hawaii and the second-highest point above sea level of any island on Earth. Most of the mountain is under water; when measured from its oceanic base, Mauna Kea is over 10,000 m (33,000 ft) tall and is the tallest mountain on Earth, taller than Mount Everest in Nepal and China. Mauna Kea is about a million years old, and has thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous, resulting in a steeper profile. Late volcanism has also given it a much rougher appearance than its neighboring volcanoes; contributing factors include the construction of cinder cones, the decentralization of its rift zones, the glaciation on its peak, and the weathering effects of the prevailing trade winds. Mauna Kea last erupted 6,000 to 4,000 years ago and is now considered dormant.
Mount Everest In the early 1960s, the Nepalese government coined a Nepali name for Mount Everest, Sagarmāthā or Sagar-Matha[30] (सागर-मथ्था).[31]
