what type of activity is indicating that mauna loa may be entering a new period of volcanic activity
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]
Kīlauea Kīlauea (/ˌkiːlaʊˈeɪə/, US: /ˌkɪləˈweɪə/; Hawaiian: [tiːlɐwˈwɛjə]) is a currently active shield volcano in the Hawaiian Islands, and the most active of the five volcanoes that together form the island of Hawaiʻi. Located along the southern shore of the island, the volcano is between 300,000 and 600,000 years old and emerged above sea level about 100,000 years ago.
