Data quality control of the Malta Seismic Network (2015-2024)

Abstract

Malta lies in a seismically active region of the Central Mediterranean, where local and distant earthquakes pose a hazard to the local community. To address this, the Malta Seismic Network (MSN) was established, growing from three to eight stations over the past decade. This study reviews the performance and data quality of the MSN, assessing availability, noise levels, timing accuracy, and sensor orientation. Results show generally reliable operation, though a few individual stations faced challenges such as power shortages, equipment failures, and timing inconsistencies. The network has proven crucial during seismic crises and of benefit for geophysical investigations. Future developments aim to expand the station coverage and strengthen international collaborations, ensuring the MSN continues to advance earthquake monitoring and geophysical research in Malta and beyond.
