And a few hours later the death toll has exceeded 1000 :-(
Latest report- over 2,000 dead, and over 2,000 injured.
Fires, then floods in Greece, an earthquake in Morocco. That area is not having a good run.

At least 2100 now dead and that number will likely jump by tomorrow as experts explain why it was so bad. :-(

Afghanistan earthquake: At least 120 killed and over 1,000 wounded in 6.3 magnitude quake.

At least 320 people have died in strong earthquakes that battered northwestern Afghanistan on Saturday, the United Nations has said.

Two 6.3-magnitude quakes struck an area 25 miles northwest of the city of Herat, and were followed by four large aftershocks, the United States Geological Survey (USGS) reported.

Four villages in the Zenda Jan district in Herat province bore the brunt of the quakes and aftershocks as dozens of houses were destroyed following the devastating quakes.

The United States Geological Survey reported the 6.3 magnitude tremblors, with an aftershock measuring a magnitude of 5.5......

Death toll exceeds 100 after magnitude-6.4 earthquake hits Nepal.

At least 128 people have been killed and dozens injured after an earthquake struck western Nepal on Friday, with witnesses saying houses in the area collapsed and buildings as far as New Delhi, India, shook.

Nepal's National Earthquake Monitoring and Research Center measured a magnitude-6.4 earthquake and said its epicentre was at Jajarkot, which is about 400 kilometres north-west of the Nepal capital, Kathmandu.

Officials said early on Saturday that the death toll was expected to rise, noting that communications were cut off with many villages.

The US Geological Survey had initially said the earthquake had a preliminary magnitude of 5.6 and occurred at a depth of 17.9 kilometres......
Stay safe.

The south western peninsula of Iceland is shaking well, and a volcanic eruption is expected there any time soon.

A sensible move is made.

Iceland's iconic Blue Lagoon closes as guests leave due to fears of potential volcanic eruption.

Iceland's famed Blue Lagoon geothermal spa says it is temporarily closing as a precaution, after thousands of small recent tremors raised fears of a potential volcanic eruption.

"The Blue Lagoon has made the proactive decision to temporarily close its operations for one week although the current phase of uncertainty has not been elevated by the authorities during this seismic period," it said in a statement posted to its website.

The closure of the Blue Lagoon, Iceland's most popular tourist site, known for its steaming milky blue water was set to take place on Thursday local time.

The announcement came after frightened guests left the Blue Lagoon hotel in the night, with at least 40 being picked up by taxis, according to a report in the local Vikurfrettir newspaper.....
Stay safe.

Cheers.

The number of quakes in Iceland is getting to the "almost continuous" state, many of them are grater than M3, with a couple poking towards M5. All sorts of alert levels have been set, and the situation is changing by the minute, with an eruption expected somewhere the Blue Lagoon at any time (hours to days). Plans are in place to evacuate Grindavik (the only "town" in the area), but some are already leaving.

A update at 11:30 and the town of Grindavik is being evacuated:

(This page is updated periodically, with the hottest news at the top, and each post has a time&date)

A couple of notes about the map Carlos posted:
The map is updated at roughly 30 minute intervals
The green stars are quakes of M>3
Grindavik, the power station mentioned in the link, and the Blue Lagoon are in the middle of the mass of green stars

A real time map of the seismic event is available at https://vafri.is/quake/

Some webcams of the area are on Youtube.

Also causing concern is Campi Flegrei, west of Naples on northern edge of the bay, in the Phlegraean Fields. About 14 km from Vesuvius which is on the other side of Naples.

No obvious news. But the magma inflow continues, the risk of an eruption near or in Grindavik remains unchanged:

Following on from Scrooge McDuck's post.
From personal contacts living in Iceland:

The area around Grindavik (Iceland) continues to be unstable with more subsidence leading to buildings being damaged & destroyed, roads being made into crazy roller-coasters and ponds getting bigger.
Meanwhile the town is deserted, and the people have either relocated themselves to family and friends (Iceland is a very close, family oriented, community) or rented accommodation. They are being offered phycological support by various organisations, but one concern for many is the loss of jobs (Grindavik was a busy fishing & fish processing centre) and thus money (discussions about insurance & state aid take place regularly).

So far, apart from gas escapes around Grindavik there has been no "real" volcanic activity, only time will tell if this is going to be "the big one", or just a restless rumble.

Map of the area around Grindavik showing how much the land has deformed in recent days:
https://en.vedur.is/about-imo/news/bigimg/4511?ListID=0

The scary bit is that the western half of the town has dropped over a metre (say 4-5 feet), while an area to the east has risen by about half a metre (about 2 feet).
This map does not show where the cracks in the town have opened up, but most would appear to be running along a north easterly line away from the port which is near the centre of the town.

An update from this side of the world on Iceland and the future is looking bleak. :-(

Thousands have been evacuated as experts warn “time is up” for an imminent volcano eruption that is expected to burn for centuries.
Regarding Icelandic volcanoes one thinks of the active ones Hekla, Katla, Krafla in the Eastern or Northern volcanic zone which erupted in recent centuries. But there are no volcanoes on the maps of the Reykjanes peninsula near the capital. Iceland's only international airport Keflavik... only 20 kilometers north of Grindavik. Difficult times ahead...

Three eruptions have occurred since 2021, which experts say mark the beginning of a new geological era on Iceland’s southwestern peninsula, which had previously laid dormant for 800 years.

https://www.wired.com/story/iceland-volcano-explode-eruption-when/ wrote:
[...] But earlier this month, scientists tracked what appeared to be a huge volume of magma gathering below the Svartsengi area. It quickly rose toward the town of Grindavík last Friday night, stopping just shy of the surface and consequently prompting the town’s swift evacuation.

Even knowing that the next eruption could happen in one of several places on the peninsula, including somewhere a little closer to urban infrastructure, this development still shocked scientists. “The extension of the seismic activity under the town of Grindavík and the shallow waters south of the town did come as a surprise, simply because previous volcanic fissures have not extended so far southwest,” says Þorvaldur Þórðarson, a volcanologist at the University of Iceland.

Why the sudden shift? Scientists suspect that the 2021 eruption kicked off a decades-long period of fissure eruptions across the peninsula; something similar happened 800 years prior. This possible fourth eruption is certainly part of that new era. [...]
Initial estimates hint that the amount of magma involved is more substantial than the peninsula’s past three eruptions, and it also flowed into the Svartsengi area at an astonishing speed. “Why the magma inflow rate appears to be so much higher this time, and indeed where it was sourced from, remains an important open question,” says Winder. Considering the seemingly hefty volume of magma, the potential for a long-lived eruption, or an otherwise very prolific eruption of lava, is high—but paradoxically, as with many eruptions, it could be that only a fraction of that molten rock sees daylight.
