Lava flow velocity exerciseHistorical lava flows from Mauna Loa are shown in gray, and the numbers along the coastline indicate the approximate time that the lava flows took to reach the sea after the vent(s) opened high on the volcano. Lava flows from the 1984 eruption of Mauna Loa are shown in the inset map. Start and end times, or duration for 1859 flow (#4), are indicated for each flow unit.

- Calculate the lava flow velocities (in km/hr) for the three lava flows indicated with arrows (#1-3) in the inset map at the top.

- Calculate the lava flow velocity (in km/hr) for the 1859 lava flow on the north side of Mauna Loa (#4) that traveled around Hualālai Volcano.

-Indicate on the maps where the vents were for the four numbered lava flows?
