The Nevado del Ruiz volcano in Colombia is always monitored for potential activity, given its history and characteristics such as the presence of glaciers or nearby population centers. However, the risk of major eruption can change over time as various factors evolve. To determine if it's currently on the verge of a major eruption. it's crucial to rely on expert observations, official reports, and updated volcanic activity information from accredited sources such as national geological surveys or volcanological institutes

While there may be periods of increased activity like ash emission, gas release, or seismic behavior at particular time. the level of alert or warning often indicates the severity of risk. if any official declaration indicating an imminent or major eruption from relevant organizations, these should be consulted along with recommendations related to public safety in such scenarios.
