The bridge over Gígja is around 340 meters wide, but the river is now about 200 meters wide at the bridge. The water is flowing at about 630 cubic meters per second compared to 130 cubic meters per second on Sunday. This indicates that the river is rising faster than in the last big flood in 2004. Other rivers are not showing signs of flooding.
At Grímsvötn, the very active volcano that last erupted after the flood in 2004, earthquake activity is being closely monitored. An earthquake of 2.4 on the Richter scale was measured at 5 pm on Monday, but there has been no activity since.
According to mbl.is scientists say that an eruption could well start after the flood. If the potential eruption is similar to the one in 2004, it might begin today, i.e. Tuesday afternoon.
