In theory the magma chamber under Svartsengi will have accumulated enough lava to possibly trigger another magma run over the next few days or couple of weeks. According to the Iceland MetO the threshold seems to be 8-12 million cubic meters and it's at 7.6m now.
You'd assume an eruption is very likely just because there's clearly a pathway there that the lava can push through but in theory it might not make it to the surface I guess.
Be interesting to see where this one comes up if it does erupt, hopefully for the sake of the town it's in a similar area to the last one and doesn't trend south and erupt near or in town or just out to sea.
