On March 6, 1978, the mayor of Nara City, Japan, Tadao Kenda, pointed out in a press conference that a cloud in the northern sky indicated an impending earthquake. Indeed, the next day, a 7.8 magnitude earthquake occurred near the Sea of Japan. The method of predicting earthquakes through earthquake clouds garnered attention in the academic community, but it also faced skepticism. Earthquake clouds come in various shapes and complex colors, often appearing in composite shades such as iron gray, orange-yellow, and reddish-orange. They typically manifest in the early morning or evening and are distributed perpendicularly to the epicenter. Chinese seismologist Lyu Dajiong compiled a distribution map of earthquake clouds and suggested that the ground projection of the intersection points of earthquake clouds indicates potential earthquake zones. He also proposed that earthquake clouds might appear above fault zones far from the epicenter but under concentrated stress, where geothermal energy escapes through the fault, forming band-shaped earthquake clouds. Radial earthquake clouds may emerge at the intersection of highly stressed faults. Although these theories explain some characteristics of earthquake clouds, they still lack empirical data to support them.
