Icelanders were working Friday to get hot-water supplies fixed in thousands of houses a day after a third volcanic eruption in two months, as experts said the tremors had eased.
Repairs on the network — which is also a source of heating — went on overnight in temperatures as low as minus 14 degrees Celsius (6.8 degrees Fahrenheit), utility company HS Orka said.
The lava flow that destroyed the pipes the previous day had made it difficult for the repair teams to gain access, it added on its website.
Experts at the Icelandic Meteorological Office (IMO) however said Friday that volcanic activity was significantly down from the previous day’s eruption.
An estimated 15 million cubic metres of lava flowed out in the first seven hours of the eruption, early Thursday, it said.
“For the past hours no lava fountaining has been observed on web-cameras but activity within the craters might still be ongoing,” the IMO said in a statement.
But while the decrease was significant “it is still too early to declare if it has come to an end”, it added.
The lava spewed out from a new volcanic fissure on Iceland’s Reykjanes peninsula in the country’s southwest.
It cut the supply of hot water, which is also used to heat houses, in the southern part of the peninsula, known as Sudurnes, home to some 28,000 inhabitants.
Dramatic images showed lava flowing over a road leading to Iceland’s famed Blue Lagoon geothermal spa, which had been evacuated, and the flow also crossed over a key water pipe.
“The plan is to fix the problem hopefully in the next few hours,” Hjordis Gudmundsdottir, spokeswoman for Iceland’s Department of Civil Protection and Emergency Management, told AFP Friday.
“It will take a few hours to put the hot water back in the system.”
In the meantime, schools, public pools and sport facilities in the region were closed on Friday, she added.
Electricity is still working, but the authorities are urging people in the region to limit consumption.
The 4,000 residents of Grindavik had to be evacuated on November 11 after hundreds of earthquakes damaged buildings and opened up huge cracks in roads, shrouding the village’s future in doubt.
The eruptions were some 40 kilometres southwest of the capital Reykjavik.
