what are some studies conducted regarding this in modern times?
Dana's "great fissure" theory served as the working hypothesis for subsequent studies until the mid-20th century. He concluded that the Hawaiian chain consisted of two volcanic strands and coined the terms "Loa. He proposed localized volcanic activity along a major fissure zone.
Hawaii hotspot

Dana remained interested in the origin of the Hawaiian Islands, and directed a more in-depth study in 1880 and 1881. He confirmed that the islands' age increased with their distance from the southeasternmost island by observing differences in their degree of erosion. He also suggested that many other island chains in the Pacific showed a similar general increase in age from southeast to northwest. Dana concluded that the Hawaiian chain consisted of two volcanic strands, located along distinct but parallel curving pathways. He coined the terms "Loa" and "Kea" for the two prominent trends. The Kea trend includes the volcanoes of Kīlauea, Mauna Kea, Kohala, Haleakalā, and West Maui. The Loa trend includes Lōihi, Mauna Loa, Hualālai, Kahoolawe, Lānai, and West Molokai. Dana proposed that the alignment of the Hawaiian Islands reflected localized volcanic activity along a major fissure zone. Dana's "great fissure" theory served as the working hypothesis for subsequent studies until the mid-
where did the magma that erupts from mauna loa likely form The volcano's magma comes from the Hawaii hotspot. where is mauna loa? Hawai, U.S. state. what is it? It is one of five volcanoes that form the Island of Hawaii. does anyone monitor this place? Hawaiian Volcano Observatory and Mauna Loa Observatory. what is the above stated hotspot? The Hawai’i hotspot is a volcanic hotspot located near the namesake Hawaiian Islands. is there any theory related tho this? Canadian geophysicist J. Tuzo Wilson proposed the hotspot theory to explain these zones of volcanism so far from regular conditions, a theory that has since come into wide acceptance. how frequently does it erupt? Over the last six million years they have been far higher than ever before, at over per year. how did it evolve? It is built from five separate shield volcanoes that erupted somewhat sequentially, one overlapping the other. what it the temperature here like? The surface heat flow anomaly around the Hawaiian Swell is only of the order of 10 mW/m.

Hawaii hotspot [SEP] Modern studies
Three of the earliest recorded observers of the volcanoes were the Scottish scientists Archibald Menzies in 1794, James Macrae in 1825, and David Douglas in 1834. Just reaching the summits proved daunting: Menzies took three attempts to ascend Mauna Loa, and Douglas died on the slopes of Mauna Kea. The United States Exploring Expedition spent several months studying the islands in 1840–1841. American geologist James Dwight Dana was on that expedition, as was Lieutenant Charles Wilkes, who spent most of the time leading a team of hundreds that hauled a pendulum to the summit of Mauna Loa to measure gravity.
