Map of today’s active volcanoes

Reykjanes (Reykjanes peninsula (SW Iceland)): The activity at the eruption site has waned.
The fountaining has shifted from the initial entire fissure length to three eruptive vents above, which have been building spatter cones.

Emissions of lava continue to feed the spreading field of lava advancing south-southwest.

…8 Feb:
Unfortunately, after the road was being cut by the lava flow, the advancing flow front continued to destroy another important objects in its path. Recently about half an hour ago, the lava reached the hot water pipe, the main transport channel for hot water from Svartsengi to Reykjanesbær. From the live stream webcam imagery, abundant vapour emissions indicate that the pipe has undergone a damaging.
Hot water will be safe for the next hour until another precaution will be taken.

In order to save hot water, residents are advised to keep waiting for the starting of electric heating as long as possible.
There is a risk that the travelling lava flow will cross another important pipe, and given the current discharge rate of the lava, the risk continues to increase.

…8 Feb:
A new hazard assessment map for Grindavík area has been published by the Icelandic Met Office due to the ongoing eruption.
The danger in the highest risk zones has increased significantly as the eruption commenced.

The highest danger zones:
2,3 – very high (purple)

…8 Feb:
New drone images of the lava flow were published by Gregory Paul De Pascale, associate professor at the Department of Geology of the University of Iceland.
…8 Feb:
The lava flow front already cut the road and continues to advance towards the heat supply for Reykjanesbær and all of Suðurnesin. The fluidal basaltic lava flow, emerging from the chain of fissure vents, travels at high discharge rates (approx. 500 m per hour) and is currently less than a kilometre from the important building.

…8 Feb:
The effusive eruption continues.
At about 05:30 AM this morning, a swarm of small-intensity earthquakes began to occur northeast of Sýlingarfell. Following the elevated seismic tremor, the new eruption started at approximately 06:00 AM local time.

Magma propagated the surface along the 3 km long eruptive fissure arranged in a northeast-southwest oriented linear shape, extending from Sundhnúk in the south to Stóra-Scógfell.
The height reached by some lava jets surpassed 80 meters but varies in a range between 50-80 meters. A constant copious gas plume reaches an altitude of about 3 km as a sudden release of CO2 emissions accompanies the initial stage of the eruption onset.

…8 Feb:
A new eruption commenced on the Reykjanes Peninsula early this morning.
At about 06:00 local time, a new eruptive fissure opened at a similar location to the 2023 December eruption site.

Bursting lava fountains are erupting along the entire fissure, known as curtains of fire, generating hot fluid blebs falling to the ground, coalescing, thereby forming lava flow field.
The duration is expected to be short like the last two which were a couple of days long.

Poas (Costa Rica): (8 Feb) The OVSICORI-UNA surveillance webcams continue to monitor minor phreatic-type explosions from the summit crater lake.
During 30 Jan-6 Feb, about 600 eruptions per day have been recorded daily, generating old country rock, indicating interaction between water and heated conduit-rocks rather than magma itself, to about 50-100 meters above the lake. On 4 February, a hydrothermal explosion produced a plume of steam, gas and a mixture of water and sediments to about 200 meters above the lake.
