In the context of recent eruptive activity reported from Bezymianny Volcano and the broader
understanding of stratovolcanism, consider the following statements:
1. The 1956 eruption of Bezymianny Volcano represents a classic example of a lateral
blast followed by sustained dome growth, a behavior commonly associated with viscous
intermediate magmas.
2. The location of Bezymianny on the Kamchatka Peninsula is tectonically linked to a
convergent plate boundary system that forms part of the Ring of Fire.
3. Stratovolcanoes, including Bezymianny, are dominated by basaltic lava flows, which
explains their steep slopes and highly explosive nature.
4. The coexistence of lava domes, pyroclastic flows, and ash plumes at Bezymianny
reflects the alternating deposition of lava and fragmental material, giving stratovolcanoes
their composite character.
Which of the statements given above are correct?
