Iceland eruption continues steadily, smaller vent at side of main cone becoming more active

The eruption continues with little changes and stead lava output. In the past hours, the hornito (small cone-shaped vent) at the side of the main vent has been becoming more active, seen left in the image of the live camera.

In a tweet, Iceland's Morgunblaðið (mbl.is) actually mentions that a "new smaller fissure has opened" up onn the side of the main crater, but it is not quite the case. To speak of a new fissure in the context of this eruption would imply a new deeper structure that formed a completely new pathway for magma to rise from the reservoir to the surface. What we're seening is actually still the same fissure where one of the earlier eruption points is now becoming more active again - as the main vent grew larger and taller with time, the rising magma seems to be finding an easier way to erupt from a lower point.
Said this, the scenario that new eruptive fissures open in the area is a real possibility and might well occur at some point.

Vigorous lava spattering is seen from the main vent, which has been building a steep-sided cone above the eruptive fissure. Over its two and half days of existence, this cone (also called a hornito currently) has been growing, sometimes partially collapsing, and thus changing its shape a lot, and it might evolve eventually into a new small mountain.

The new eruption, now called the "Geldingadalsgos" eruption by the Icelandic media, continues steadily. It has been producing slowly advancing lava flows inside the Geldingadal valley. The Icelandic Met Office and local news outlets published many new photos from the ongoing eruption this morning. ... Read all
