New Holuhraun lava is now 3 times larger than NYC’s Central Park, the volcanic activity at the fissure is continuous 1448

In under four days, the volcanic fissure in Holuhraun has spewed up lava that covers tripple the size of New York's Central Park. In other words, it would stretch from 110th street through Midtown, SoHo, the Financial district and out to the Hudson river south of Manhattan island, if it would keep the three avenue blocks width of the park.

According to the Icelandic Met Office (IMO) the volcanic activity at the fissure is continuous. The fissure is 1.5 km (0.93 mi) long but the eruption primarly takes place on a 600-800 meter (1.968-2.625 ft) long central section.

IMO reports that persistent seismic activity is still detected in the northern part of the dyke intrusion, between the eruption site and south to about 6 km (3.8 mi) into Dyngjujökull outlet in Vatnajökull glacier. Event rates are lower than in recent days. Some events are detected in Bárðarbunga caldera, all of them were smaller than magnitude 4 since the M5.5 event last night (September 3rd).

The origin of the increased tremor signal since this morning is still unclear and data is still analysed. Scientists interpreted the signal as a possible sub-glacial eruption and experts and members of the press were evacuated from the Holuhraun area. However there are no signs of a sub-glacial eruption under the ice cap of Dyngjujökull.

No obvious changes such as increased water flow or cauldrons on the glacier surface were observed from scientists who made a surveillance flight over the ice cap this afternoon. Water meters in Jökulsá á Fjöllum river do not show any unusual changes in discharge and electric conductivity.

The low frequent tremor signal is still continuing, its strength is variable.
