The study reveals a complex pattern of magnetic anomalies at the Tunguska epicenter, suggesting possible impact-related remagnetization.
Anomalies align with the presumed trajectory of the airburst, indicating transient electromagnetic effects could be influencing magnetic patterns.
This unmanned aerial vehicle survey covered 30 square kilometers and is the first detailed analysis of the area's magnetic anomalies.
Our findings emphasize the need for future rock magnetic studies to confirm theories about transient remagnetization at the site.
