Sinkhole Swallows Farmland in Indonesia
A large sinkhole has collapsed on farmland in Indonesia, swallowing an area of three hectares. The event highlights the risk of natural disasters in the region, which can disrupt agricultural production and logistics. A separate 5.0-magnitude earthquake also struck the country's Aru Islands region on February 17.
- The sinkhole is located in Pondok Balik village in Central Aceh, a region where the ground consists of soft volcanic rock and sandy soil from an ancient volcano. This geological composition, when combined with heavy rainfall and seismic activity from the nearby Sumatran fault line, makes the area prone to collapse. - This specific event has destroyed plantations of coffee, chili, and sugarcane, which are key sources of income for local families. The Central Aceh Regent, Haili Yoga, confirmed that data on agricultural losses has been escalated to the central government. - Beyond farmland, the ground collapse has engulfed a section of the main road connecting the district to a neighboring regency and forced the relocation of high-voltage electricity towers to prevent power outages. - The sinkhole, which is approximately 100 meters deep, is considered a unique case by geologists as it formed in volcanic rock, whereas sinkholes in Indonesia typically occur in karst landscapes where water dissolves underlying limestone. - While no one has been injured, the sinkhole continues to expand and is now 300 to 600 meters from a village of approximately 800 people, prompting authorities to declare it a danger zone. - Human activity, particularly excessive groundwater extraction for agriculture or industry, is a significant contributing factor to land subsidence and sinkholes in other parts of Indonesia, including Java and Sumatra.
