Fast Facts

• When: Thursday, April 23, 2026, at 12:59 p.m. local time.
• Epicenter: Centered near Holcomb and Cooter, MO (approx. 12 km deep).
• Impact Zone: The tremor was felt across four states, including Missouri, Arkansas, Tennessee, and Kentucky.

Impact & Damage

While the quake was strong enough to rattle windows and move furniture, no major injuries or structural damage have been reported. Most residents described it as a sudden, brief jolt that lasted only a few seconds.

Why It Matters

Quakes of this magnitude are relatively rare for the region. While the New Madrid fault is active, most of its activity consists of micro-quakes under 2.0. Yesterday’s event is a clear signal that the fault remains a significant geological feature.
