Reminds me of the coincidence in Mexico City’s earthquake warning system. Mexico City runs an earthquake drill every year on September 19, the anniversary of the deadly 1985 Mexico City earthquake.
Well in 2017 there actually was another deadly earthquake on that same day, 2 hours after the official drill, the sirens went off for the second time that day, as the ground started shaking. There wasn’t enough advance warning to actually have people disregard it as a false alarm, though, because by the time the sirens went off the earthquake could already be felt.
