Explanation: 

Detailed explanation-1: -It last erupted for 16 months starting in September 2021, and for about two weeks in November 2021, Hawaii had two volcanoes, Kilauea and Mauna Loa, spewing lava side by side. Mauna Loa had not erupted in 38 years.

Detailed explanation-2: -Kilauea volcano is erupting. At approximately 4:34 p.m. HST on January 5, 2023, the USGS Hawaiian Volcano Observatory detected a glow in Kilauea’s summit webcam images, indicating that the eruption has resumed within Halemaʻumaʻu crater in Kilauea’s summit caldera, within Hawai’i Volcanoes National Park.

Detailed explanation-3: -Examples of shield volcanoes are Kilauea and Mauna Loa (and their Hawaiian friends), Fernandina (and its Galápagos friends), Karthala, Erta Ale, Tolbachik, Masaya, and many others.

Detailed explanation-4: -Kilauea is a basaltic shield volcano, erupting a type of basalt known as tholeiite. This type of lava is the dominant extrusive during the shield building (the main stage) of hawaiian volcanism and is the dominant basalt type erupted on Earth.

Detailed explanation-5: -Kilauea differs from Mauna Loa in two principal respects, both minor matters volcanologically. One is the greater amount of explosive debris in the vicinity of the caldera. The other is the lava lake activity that existed for many years in the caldera (Figure 5).
