Catalogue summary

Two weeks of dense-network observations located 708 Spitak aftershocks and resolved five rupture segments, including thrust and hidden shear structures near the Pambak-Sevan fault.

Why this matters

The fault geometry and N344° compression estimate provide detailed Armenian seismic evidence for reconstructing the 1988 rupture and regional hazard mechanics.
