The project logo supports the visual identity of the project, and is aligned with the project’s mission, thematic focus, and target audience.

The foreground graphic of the logo is a map of Europe, with clear outlines of countries, overlaid on a globe-like projection. The green circular arcs resemble seismic waves or signal transmission, indicating monitoring or early warning systems — core aspects of NFOs. The network of nodes (in orange color) symbolizes the idea of connected NFOs, representing multidisciplinary cooperation and data integration. Its placement over Europe suggests a continental-scale scientific effort.

The network and seismic elements highlight technological and collaborative goals, consistent with building a pan-European fault observatory system.
