Mediterranean February 12 Sonic Boom update

2026, February 12. Spain, Balearic Islands. Residents across Mallorca, Menorca, and parts of the Spanish mainland reported hearing and feeling loud "sonic booms" and window-rattling vibrations. While local weather services (AEMET) confirmed a major storm ("Squall Nils") was impacting the region with 90 km/h winds, the specific acoustic shocks were inconsistent with standard thunder or wind gusts. February 13–15, 2026: No military exercises were scheduled in the Balearic Sea for this period. Inquiries to the Spanish Air Force regarding supersonic flights yielded no confirmation of activity. Seismic Data: A seismic station at Isla Plana, Murcia (on the coast facing the Balearic Sea) recorded an event at 10:05 AM. Magnitude: 3.2. Energy Yield: Approximately 4 x 10^9 joules (equivalent to roughly 1 ton of TNT). The depth was logged as 0 km, which is a classic indicator of an atmospheric source (like an airburst) rather than a tectonic earthquake. The "Non-Earthquake" Signature: Local reports across Mallorca and Menorca described "window-rattling" and "concussive" vibrations. Since the seismic sensors recorded this energy as an N-wave (a pressure front pushing on the ground), it confirms the shock originated in the air.
