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 On May 17, 2018 at 4:17 AM, the volcano explosively erupted at the summit in Halemaumau Crater, throwing ash 30,000 feet into the air.[4] Summit explosions have caused the long-term closure of the KÄ«lauea section of Hawaii Volcanoes National Park, and vigorous eruptive activity is ongoing in lower Puna, where lava entered the ocean in three places, destroyed Hawaii's largest freshwater lake, covered substantial portions of Leilani Estates and Lanipuna Gardens, completely inundated Vacationland Hawaii and all but three houses in the Kapoho Beach Lots. Lava also filled Kapoho Bay and extended new land nearly a mile into the sea.[5][6] The total number of houses taken by lava since May 3, 2018 was officially announced on June 7 as approximately 600.[7][8] On July 9 the official total had increased to 700 houses.[9]
