Answer:

a) Maximum height (elevation) of the volcano above sea level: The maximum height (elevation) of Mt. Alayta above sea level is not provided in the information given.

b) Likely composition of the volcano: Based on the location of Mt. Alayta in Ethiopia, it is likely that the volcano is composed of basaltic lava flows, as basaltic volcanism is common in the East African Rift System.

c) Major geologic hazards associated with the volcano: The major geologic hazards associated with Mt. Alayta include lava flows, pyroclastic flows, and ashfall. Lava flows can destroy anything in their path, including buildings and infrastructure. Pyroclastic flows are superheated ash and gas that can travel at high speeds down the slopes of a volcano, destroying everything in their path. Ashfall can cause damage to structures and also pose a hazard to human health.

d) Overall shape and description of Mt. Alayta: The overall shape of Mt. Alayta is not provided in the information given.

e) Tectonic setting of the region: The East African Rift System is a divergent plate boundary where the African Plate is splitting apart, creating a rift valley. The region is characterized by a series of active and dormant volcanoes, as well as seismic activity.

f) Volcano type based on size, shape, and composition: Without additional information about the size, shape, and composition of Mt. Alayta, it is difficult to speculate on the type of volcano. However, based on the location in the East African Rift System, it is likely that the volcano is a shield volcano, which is typically characterized by broad, gentle slopes and basaltic lava flows.
