When an earthquake strikes, the go-to resource for most New Zealanders is GeoNet. Following an event, people quickly jump onto the site to review the magnitude and the intensity of the quake or “reported shaking”.
At Sentinel, we know that measured ground shaking across a city or region is highly variable. Using “Magnitude plus distance” as a crude estimate of damage likelihood is unreliable, uncertain and potentially dangerous. An earthquake earlier this week provided a graphic demonstration.
