Malfunctioning sensor, huh? How do we know this is the truth? This is coming from the same organization that consistently downgrades earthquake intensities for no reason. Have you ever noticed how many earthquakes there are that end in .9? 4.9, 6.9, etc. Something that costs $9.99 seems cheaper than something that is $10. It's marketing psyops. 4.9 and 6.9 earthquakes seem less powerful than 5.1 and 7.1 earthquakes.
