Did all of the lava flows associated with Mauna Loa originate at the top of the volcano? How do you know?

Look at the following volcanoes (note that the maps are of several different scales):
• Mount Vsevidof (53°07'35"N, 168°41'16"W), a composite volcano in Alaska (shown on Map T-2, Map T-21b, and Figure 34-2)
• Crater Mountain (37°52'42"N, 119°00'25"W), the highest peak of the Mono Craters, a chain of rhyolitic plug dome volcanoes in California (shown on Maps T-23a and T-23c)
• SP Mountain (35°34'56"N, 111°37'55"W), a basaltic cinder cone in Arizona (shown on Maps T-22a and T-22b and Figure 34-3)
• Mauna Loa (19°28'17"N, 155°35'41"W), a large shield volcano on the Big Island of Hawai‘i (shown on Maps T-1 and T-21a)

What will be an ideal response?


No, Several lava flows started from the side of the volcano some distance below the summit.
