Dr. Mirzam suggests that the eruption could have been triggered by an imbalance in the magma chamber, resulting from the accumulation of gasses over the years. He explains that disturbances in the magma chamber's equilibrium, often caused by the injection of new magma, can lead to eruptions. This imbalance, characterized by the buildup of gas pressure, eventually culminates in volcanic activity.

Mount Marapi, known for its eruption cycles ranging from 1 to 17 years, has a history of periodic volcanic activity. Dr. Mirzam highlights the significance of understanding these cycles, emphasizing that longer intervals between eruptions may lead to more substantial volcanic events. He points out that the last significant eruption of Mount Marapi occurred in 1991, suggesting that the recent eruption might have been overdue.

Furthermore, Dr. Mirzam discusses external factors that could influence volcanic activity, such as the proximity of Mount Marapi to the Sumatra Fault. The interaction between geological structures like faults and fractures in the Earth's crust may exacerbate volcanic instability, contributing to sudden eruptions. He underscores the importance of considering these external factors in assessing volcanic hazards and implementing effective mitigation strategies.

In light of the unpredictable nature of volcanic eruptions, Dr. Mirzam emphasizes the necessity of disaster preparedness and mitigation efforts. He underscores the importance of dedicated monitoring systems tailored to each volcano's unique characteristics, coupled with comprehensive risk assessments and community awareness initiatives.

Dr. Mirzam's insights provide valuable perspectives on the recent eruption of Mount Marapi, underscoring the complexities of volcanic processes and the critical need for proactive measures to mitigate volcanic risks and safeguard communities in volcanic regions.
