A volcano in southwestern Iceland erupted on July 16, marking the latest in a series of eruptions near the capital Reykjavik in recent years. According to the Icelandic Meteorological Office, GPS monitoring and surface deformation data suggest that the eruption is relatively small in scale and currently poses no direct threat to any infrastructure.

Since the Reykjanes Peninsula’s volcanic system reawakened in 2021, Iceland has experienced 12 eruptions. The eruptions on the peninsula are classified as *fissure eruptions*, where lava emerges from long cracks in the Earth's crust rather than erupting from a central volcanic crater. The eruption does not threaten the capital Reykjavik, nor has it released significant volcanic ash into the stratosphere, meaning air travel remains unaffected.

With a population of under 400,000, Iceland is home to more than 30 active volcanoes. Experts note that these types of fissure eruptions could recur repeatedly, potentially continuing for decades or even centuries.
