 REYJANES - ICELAND The recent unrest at Iceland's Reykjanes Peninsula has generated a lot of media attention, not to mention increasing the stress levels of those unfortunate enough to be on the receiving end of the unrest in Grindavik. Grindavik was evacuated following the events of November 10th, 2023, where a series of extremely strong quakes coupled with a rifting and dike emplacement event left the town with large fissure cracks running in a NE/SW direction, damaging roads, infrastructure, water and power services. Many apartments and homes are now uninhabitable and will need to be ..read more

 HAWAII Mauna Loa, dormant since its last eruption in 1984, and after a very long inflation period with starts, stops, and starts, entered into an eruptive phase Nov 30th (HST) with a visually spectacular eruption. The eruption began with a fissure eruption at the summit of Moku'āweoweo caldera at just around midnight. Animated 24-hour GIF of the start of the eruption via USGS/HVO This part of the eruption effused a very large amount of lava in a short period of time, but quickly ended after overfilling the SW caldera rim. Shortly after, fissures on the Northwest Rift Zone (NWRZ ..read more

 HAWAII, USA - Kilauea began a new eruption after weeks and months of inflationary tilt and occasional quake swarms. As of 3:20PM HST, USGS posted the following update: "Kīlauea volcano is erupting. At approximately 3:20 p.m. HST on September 29, 2021, the USGS Hawaiian Volcano Observatory (HVO) detected glow in Kīlauea summit webcam images indicating that an eruption has commenced within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park. Webcam imagery shows fissures at the base of Halemaʻumaʻu crater generating lava flows on the surface of the lava ..read more

Eruption at Fagradalsfjall Continues After Lull
Volcano Science And News Blog

2y ago
 In Iceland, on the Reykjanes peninsula, the eruption at Fagradalsfjall entered into a 9 day dormancy, which caused some to speculate that the eruption may be ending. This was proven false several days ago, when rock fracture volcanic quakes, and a gradual increase in tremor resulted in a new phase in the eruption. Currently the volcano is 'pulsing' with activity that ranges from 10-15 minutes of lava effusion, and about another 15-20 minutes of quiet. This pattern has continued for several days now. Today, a large lava breakout near the main erupting crater created a cascade of lava down ..read more

Why The Eruption At Fagradalsfjall Is Unprecedented
Volcano Science And News Blog

3y ago
 The eruption that began in Iceland's Reykjanes peninsula in March of 2021 has for the most part shocked scientists, volcano enthusiasts, and tourists alike. The volcano, it seemed at the time, was (or still is, depending on who you ask) part of the Krýsuvík-Trölladyngja system, which was experiencing its first magmatic eruption in some 800 years. The conventional wisdom at the time was that this was a relatively small eruption that would probably only last a few weeks. This has been proven wrong, the question now is why? One need not look much farther than Iceland itself. Icelandia is a ..read more

Second Fissure Opens Up At Fagradalsfjall

3y ago
 An approximately 200 meter long fissure has opened up to the SW of the first eruptive vents at Fagradalsfjall. The fissure opened up some 200 meters from a rescue and aid camp that was set up nearby, which was quickly dismantled and moved. New fissure outbreak at Fagradalsfjall. The new fissure can be seen below in relation to the main vent, with lave spilling down a valley to the ENE.  New fissure on the lower left. (Photographer unknown) A new fissure opening likely indicates that this eruption is far from over, and that more fissure outbreaks are possible. Nothing in the ..read more

Iceland Has Major Quake Swarm At Reykjanes Peninsula

3y ago
 Reykjanes, Iceland is experiencing another major quake swarm, with the largest quake so far at magnitude 5.7. The swarm is in the same general area as previous seismicity within recent years, and is very probably related to more magma intrusion. Magma intrusion and system inflation has been going on for about two years in this area, which is frequented by tourist visiting the famous Blue Lagoon resort spa.  Screen snip from Iceland Met Office website showing the large quake swarm. Green stars denote temblors larger than magnitude 3.  The quake swarm is assumed to be related ..read more

****BREAKING**** 10 minutes ago HST, Kilauea has now roared back to life, according to HVO. This marks the first resumption of eruptions from Kilauea since the cessation of eruptive activity after the 2018 Leilani Estates/LERZ eruption, which destroyed over 700 homes and displaced twice as many people.  It is unknown what role the water lake has had in the eruption at this time, however according to the above image, it appears to have been vaporized. There appears to be no trace of it in new images, and due to the time of night, is it unclear if a phreatic eruption has occurred, whic ..read more

Quake Swarm And Rapid Surface Deformation Continues In Iceland
Volcano Science And News Blog
by Matt
4y ago
On Iceland's Reykjanes Peninsula, an ongoing swarm of concentrated temblor activity, coupled with rapid surface inflation is raising the possibility of the first volcanic eruption in nearly two centuries near the famed Blue Lagoon. The area has many geothermal features and is once of Iceland's largest producer of geothermal energy. According to an article released on January 26th, 2020 on Iceland's Met Office website, "An inflation has been detected since January 21st and is centred just west of Mt. Thorbjorn on Reykjanes peninsula. The inflation is unusually rapid, around 3-4 mm per day and ..read more
