Advanced Seismic Event Fusion for Planetary Cave Interiors

Fusing moonquake and marsquake events into a cave-interior quilt requires a pipeline built for sparse arrivals, tidal ambient noise, and cross-mission catalogs.

A planetary cave interior has no natural illumination and almost no local seismic energy budget. If you want to know what the inside of a Marius Hills tube or a Mare Tranquillitatis skylight wall looks like, you have to borrow energy from somewhere — and the only reliable sources are moonquakes, marsquakes, and the tidal ambient field. The Nature Communications paper on InSight's first glimpses of Mars interior from seismology documented the first planetary seismic dataset outside Earth and the Moon, and it reset expectations for what a single lander can extract. The Springer review of lunar seismology meanwhile surveys the Apollo PSE legacy and the farside networks coming online, which is where the event supply for cave-interior fusion actually comes from.
