After weeks of intense earthquake activity, a volcano has erupted on the Reykjanes peninsula of south-west Iceland.
 
        
         
        
    About 4,000 people were earlier evacuated from the fishing town of Grindavik and the nearby Blue Lagoon geothermal spa was closed.
 
        
         
        
    The eruption turned the sky over south-west Iceland orange and the smoke from it could be seen from Reykjavik, which is about 42km north-east of the volcano.
 
                        
                    
                         
                        
                         
        
    The length of the crack in the volcano is about 3.5km, shown in the map below, and the lava was flowing at a rate of around 100 to 200 cubic metres per second after the initial eruption, according to the Icelandic Met Office.
 
        
         
        
         
        
         
        
    Iceland has been on high alert for a potential volcano eruption for several weeks and local residents were ordered to leave as a precaution. There were no reports of injuries.
 
        
         
        
         
        
    Scientists are continuing to monitor activity at the site and say that while the eruption is weakening, new vents could open at short notice.
