    ByTeo Blašković

    More than 4 700 earthquakes have been detected in the area between Fagradalsfjall and Keilir, Reykjanes Peninsula, Iceland since the start of seismic swarm on July 4, 2023. Ground deformation (GPS) observations show significant movements, indicating magma propagation in the region where earthquakes are highly concentrated. Magma intrusion is close enough to the Earth’s surface that a volcanic eruption could occur without further escalations in seismic activity or ground deformation.

    After 89 days of Orange alert due to increased seismic activity, Colombia’s geological service lowered the Nevado del Ruiz volcano’s alert level to Yellow on June 27, 2023. The de-escalation follows a period of decreased instability, paving the way for the potential easing of preventative measures.
