Fagradalsfjall (Reykjanes Peninsula, Iceland): A new eruptive fissure opened today located approx. 1 km northeast of the growing cone as the seismic network detected at 11:37 local time a sharp peak in tremor at 1 km depth. According to the Icelandic Met Office (IMO), the new eruptive fissure is about 500 m long and has been producing constant lava fountains. A few small spatter cones have been forming from a lava spattering along the fissure. Fortunately, the main RÚV webcamera zoomed on the beginning of the event at the right time as can be seen in the video below.
According to the University of Iceland, a new lava flow from the fissure vent continues at extremely high discharge rate as a viscosity of the flow is about 10^2 Pa. The lava flow has been traveling east and continues to fill up the Meradalir valley, adjacent to Geldingadalir valley, where a new lava flow field is forming.
