Trader consensus on Polymarket implies a roughly 0.45 expected magnitude 6.5 or greater earthquakes worldwide for April 13-19, per the 64% odds for zero aligning with a Poisson distribution from USGS long-term global seismicity data showing about 50 such events annually—or under one per week on average. No M6.5+ quakes have occurred in the first three days of the window, per USGS real-time catalogs, following a quiet period after the April 1 M7.4 near Indonesia and earlier 2026 activity clustered in March. Seismic monitoring detects no unusual strain buildup, aftershocks, or swarms along major fault lines like the Ring of Fire to suggest elevated risk. USGS feeds will provide continuous updates through April 19 resolution, with inherent uncertainty in short-term event timing.
