Authorities in Iceland have lowered the threat level for the recently erupted volcano near Grindavík as no visible activity has been observed. The eruption, which started earlier this week, caused a fissure spewing lava dangerously close to Grindavík. The Icelandic Meteorological Office stated that volcanic activity appears to have ceased, but the possibility of lava flowing underneath remains. The state of emergency has been downgraded, allowing limited access for evacuated residents. Authorities are monitoring the situation, considering protective measures for the geothermal power plant and discussing potential barriers to safeguard Grindavík.
