Determining Volcano Determining Volcano SpacingSpacing

•Measure the distance from Mauna Measure the distance from Mauna Loa to the other volcanoes on the Loa to the other volcanoes on the Loa trend & record in data table.Loa trend & record in data table.

•Determine the “average” spacing Determine the “average” spacing – divide total distance by # of – divide total distance by # of older volcanoes in Loa trendolder volcanoes in Loa trend

Data TableData Table

Geologic Map of South Kilauea Geologic Map of South Kilauea IslandIsland • The Hilina Slump is a

large landslide caused by lateral spreading of the volcano.

• Loihi is the youngest volcano on the Loa trend.

• Hohonu Seamount is a Cretaceousage volcano.

• QTa is a thin apron of nearly flat sediment

• Qpe is the undisturbed submarine lava flows on the flanks of the volcanoes. Qy is lava fields.
