Shades of blue, red, yellow, green, pink, and violet are not uncommon.
The phenomenon is also known as the Northern Lights. And observers may see scattered clouds with a strange glow, broad streamers, bright arcs, or shooting rays that light up the sky.
In Iceland, the early autumn until spring is the Aurora Borealis season.
How the Northern Lights met a Volcano
Iceland has a lot of earthquake activity. It is located at the intersection of two tectonic plates, which are constantly drifting in opposite directions. And more often than not the earthquakes are centered near a volcano. And heightened activity is often a sign that a volcano is getting ready to erupt.
Every year thousands of quakes are recorded. Iceland recorded over 40,000 earthquakes in the three weeks leading up to the eruption of Geldingadalur on the Reykjanes Peninsula.
According to National Geographic, until 2021, the Geldingadalur volcano had not erupted for 6,000 years. And it’s estimated that there wasn’t an eruption on the entire Reykjanes Peninsula in over 800 years. The peninsula is a sheltered valley far from any towns or infrastructure.
