Video (1:26 min) from Grindavik: deep crack in road; vertical offset sideways: https://www.visir.is/k/19753e84-15e2-4b8d-ad0f-0f62a6481576-1699886659509/sig-og-sprungur-vid-ithrotthus |

One reason for there not being any volcanos shown on many maps of the Rekjanes peninsular is that the whole area is effectively one large volcanic region - much of the land surface is less than a few thousand years old, indeed the area around Grindavik is only about a thousand years old. There are at least three parallel chains of volcanic craters running north east across the peninsular, with large relatively flat lava flows between them (both Keflavik and Reykjavik are built on such "old" flows). The last "major" eruption in the area was only about 800 years ago, but there have been a number of very minor eruptions since then. Further of course is the shear amount of geothermal activity, some of which is harnessed by large power (both electrical and thermal) stations, some as tourist attractions (The Blue Lagoon), and some just adds a very indelicate stench to the air in the area.

If you look at a map of Iceland and the 'Mid-Atlantic ridge' you can see this not so much a volcano and more of a rising of magma filling it the gap between the American and Eurasian tectonic plates as it widens. |

Hopefully, another large crack occurs far away from town which then gets 'filled up'.

Iceland may spray water onto lava to save town in the event of volcanic eruption. Icelandic authorities said they were considering pumping water onto any lava that spews out if a volcanic eruption threatens the evacuated town of Grindavik.Stay safe. |

But in a bulletin, the Icelandic meteorological office said the probability of a sudden eruption "is decreasing every day and is considered low" due to declining magma flow and seismic activity. Just had a look at the seismic data https://vafri.is/quake/ and it has certainly decreased. It is now saying 20 events in the last 6 hours, a week ago it was more like 300 in 6hrs. |

It seems that the pressure is building up again. Iceland is bracing for a possible volcanic eruption and the “most likely” place is now next to one of the country’s biggest tourist attractions. Stay safe. Cheers. |

Looks like there has been an eruption in the last few hour, to the East of the Blue Lagoon, and NNE of Grindavik. https://www.youtube.com/watch?v=iqF5YQRdhtw There was a quake over 4 and there is now over 300 events in the last 6 hours. |

Notice a while ago. Longer than the one last year. Understand it's got greater volume too. Flowing both directions of the fissure. |

Northwest China cops a shaking. Rescuers battle sub-zero temperatures as more than 120 killed by China’s deadliest quake in nearly a decade. At least 126 people were killed and hundreds more injured after an earthquake hit northwest China, state media reported Tuesday, as rescue teams scrambled to reach survivors in sub-zero temperatures. |

Iceland volcano eruption in 'state of equilibrium' as scientists assess activity It estimated the lava discharge from the fissure to be "hundreds of cubic meters per second," |

Another idiot caught where they shouldn't have been. :-( Hiker rescued from near lava-spewing Iceland volcano after getting lost. A hiker has been rescued from near the spewing Grindavik volcano after he became lost and sent a desperate SOS signal to a passing plane. |

Iceland, Massive increase in seismic activity in the last few hours, Running at over 100/hr at the moment. Lights went out in half of Grindavik about 2 hours ago https://www.youtube.com/watch?v=l-5QeLIn1FA, and the strongest tremors look to be under the town. https://vafri.is/quake/ |

Iceland. Eruption started about half an hour ago. Multi-cam view. https://www.youtube.com/watch?v=804nPrAUAxg |

Iceland. Another interesting view, with expert explanations, from Shawn Willsey, a geology professor in Southern Idaho. He has access to drone footage from one of the Icelandic operators. https://www.youtube.com/watch?v=MPm-J2YqzZY |

Three dead as 7.1 earthquake strikes near China’s border with Kyrgyzstan. Three people have died after a 7.1-magnitude earthquake rocked a mountainous and remote part of China’s far western Xinjiang region early Tuesday. |

Iceland is having another go - this one started more or less where the December 2023 one was, but on slightly higher ground. A couple of roads have been cut, and it's a bit close to a power plant for comfort. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Does Hawaii count as part of the Ring of Fire? It's really not on the ring but it did have a 5.7 earthquake overnight. No tsunami is expected and current reports say no damage or impacts on Mauna Loa and Kilauea. "Officials first put the quake’s magnitude at 6.3, but then lowered it to 5.7. There have also been at least eight small quakes, apparently aftershocks, in the Pahala area. Residents on the Big Island say the quake shook items from shelves and threw pictures from walls." |
