In Caxias do Sul, located in the Serra Gaúcha region of Brazil, residents experienced tremors that were alarming but were confirmed not to be an earthquake. The local Civil Defense has reassured the public that the vibrations are due to the movement of rocks in subterranean layers rather than tectonic activity. This clarification aims to alleviate public concern amid reports of loud noises and short-duration tremors that have been noticeable over the past few weeks.

The report highlights that residents described the tremors as causing minor disturbances, such as water shaking in cups, vibrating objects, and rattling windows. Armando da Silva, the commander of the Civil Defense, explained that the phenomenon had become apparent over the past twenty days, particularly in neighborhoods including Serrano, Jardim América, Universitário, Santa Fé, Belo Horizonte, and Pioneiro. The Civil Defense is actively monitoring the situation to ensure community safety and provide updates as necessary.

Authorities have ruled out any structural damage linked to these occurrences, which further indicates that the tremors, although startling, do not pose immediate threats to public safety. Civil Defense officials continue to investigate the geological causes of this underground rock movement to provide clarity and reassurance to the frightened residents, seeking to dispel myths surrounding earthquake fears.
