Iceland has been on an anxious wait waiting for the volcano to erupt, while earthquakes continue to shake its frozen land.

Since midnight on Sunday, 900 earthquakes have been recorded, but compared to the last few days their magnitude is smaller on average.

However, an underground “river” of magma with a length of 15 kilometers remains active. It is estimated that the magma is only 800 meters from the surface of the earth. The danger remains immediate for the town of Grindavik, with 4,000 inhabitants, which has been evacuated for safety reasons.

Deep cracks have appeared on city streets and in the countryside, the BBC reports.

In recent weeks, thousands of tremors have been recorded in the Reykjanes peninsula, which “awakened” volcanically after eight centuries. The region has been declared a state of emergency due to the risk of a volcanic eruption. The town of Grindavik is only 15 kilometers from Keflavik International Airport, which is operating normally. In 2010 the eruption of the Eyjafjallajokull volcano had spewed huge amounts of ash which had caused chaos in air transport across Europe. For now, however, there is no such risk.
