Comment some successes with this in the 1970s (Score 2) 29
China predicted a couple of significant quakes supposedly based on animal observations in the ealry 1970s. Then they missed the largest Chinese quake in decades in Tianjin, near Beijing, in 1976. Strange animal behavior has part of Chinese peasant folklore for millennia. Various US groups tried to replicate this methodology since the 1970s without much success. A geologist in San Jose counted lost pet ads and claimed some success. But his prediction windows were so wide they were not statistically significant. Perhaps 21st century social media could help gather observations.
