WebDec 15, 1995 · We propose a simple method for the reduction of noise in vertical seismic recordings at frequencies below 2 mHz. The method consists in subtracting the locally recorded, scaled, atmospheric pressure signal from the gravity record. The scale factor is frequency independent and can be linearly estimated from the data. While such a … WebThe NEIC issues rapid reports for those earthquakes with magnitudes at least 3.0 in the eastern United States, 3.0 in the western United States, or 5.0 (or are known to have caused damage) anywhere else in the world.
