Green earthquake (Magnitude 5.7M, Depth:18km) in Indonesia 18/04/2026 20:06 UTC, 3 thousand in MMI VI

Summary

Single-source GDACS detection — awaiting independent verification. A magnitude 5.7 earthquake struck Indonesia on April 18, 2026, at 20:06 UTC, with a depth of 18km and potentially affecting 3,000 people at MMI VI intensity levels. The moderate-strength seismic event occurred in a region significant for palm oil and nickel production.

Supply-chain impact

• Palm oil operations could face temporary disruptions if confirmed, as Indonesia supplies approximately 60% of global palm oil with plantations and processing facilities potentially in the affected region.
• Nickel mining and processing activities may experience operational delays, given Indonesia's position as the world's largest nickel producer, though impact severity depends on proximity to major mining sites.
• Transportation infrastructure including roads and ports serving agricultural and mining exports could sustain damage, potentially creating temporary bottlenecks for commodity shipments.
• Local workforce availability for plantations and mining operations may be reduced if residential areas experienced significant shaking at MMI VI levels.

Watch points

• Monitor reports from major palm oil companies operating in Indonesia for facility damage assessments and operational status updates.
• Track Indonesian government statements on infrastructure damage and any temporary export restrictions that might affect commodity flows.
• Watch for independent seismic verification and more precise location data to better assess proximity to key production areas.
