The latest cGPS deformation data around the Þorbjörn and Svartengi area confirm that the deformation, which started 27 October, continues. As initially stated, the ongoing deformation rates are higher than in previous events which occurred in a similar area in 2020 and 2022. Overall, the seismicity north of Grindavík has been declining over the past 24 hours and there are no significant changes in earthquake depths. However, it is important to emphasise that the current deformation may trigger renewed seismicity in the area that could be felt by people.

New satellite data are expected to be delivered later today, and a new interferogram will be processed as soon as the data are available. The results will allow us to identify and interpret the deformation processes that have occurred on the peninsula over the past 12 days. We expected to publish the results tomorrow.

An episode of complex volcano-tectonic unrest is currently affecting the Reykjanes Peninsula. It is interpreted to result from multiple deformation sources at depth, which are interacting and affecting a wide area across the peninsula.

The Municipal Directorate of Civil Protection of the Secretariat of Citizen Security of Puebla reports that the Popocatépetl volcano has experienced an increase in its activity in recent hours, and so far three significant explosions have been recorded , which keeps the population of Puebla on alert. the region.

Until 11:00 a.m., the volcano had recorded a total of 195 low-intensity exhalations in the last 24 hours, accompanied by water vapor, volcanic gases and, sometimes, falling ash.

However, it was around 2:20 p.m. this Saturday when the volcano emitted an impressive column of smoke accompanied by ash and gases , which was visible several kilometers away, but due to the direction of the winds, the ash did not reached the city of Puebla.

Just a week after the previous eruption, the Kuril volcano Ebeko, located on the island of Paramushir, again emitted a powerful column of ash. This time, specialists from the All-Russian State University for Civil Defense and Emergency Situations reported that the volcano had already been assigned an orange aviation hazard level due to its activity. The Shiveluch volcano in Kamchatka is now just as dangerous.

- Volcanic activity is being recorded again in the Far Eastern Federal District. The Shiveluch and Ebeko volcanoes have been assigned an orange level of aviation danger," the VNII GOChS commented on the situation.

The incredible moment when a bolt of lightning struck an erupting volcano in Guatemala was caught on camera.

The mesmerizing footage shows multiple bolts hitting the mountain, creating a spider web pattern, streaking and flashing across the sky. The lightening creates a dazzling visual spectacle as they appear to converge upon lava and smoke emanating from the mountain's vent.

The footage shows Volcan de Fuego, Volcano of Fire, and occurred on September 21st. The volcano is considered one of the world's most active, shooting ash into the sky every 15 minutes or so.

Gases from Philippine volcano sicken dozens of children, prompting school closures in nearby towns

taal
Smog containing gases from a restive Philippine volcano sickened dozens of students and prompted 25 towns and cities to shut their schools on Friday as a health precaution, officials said.

There was no imminent threat of a major eruption of Taal Volcano, which authorities said remains at a low level of unrest in Batangas province south of Manila. But they said its emission of sulfur dioxide-laden steam in recent days caused skin, throat and eye irritation for at least 45 students in nearby towns.

Classes were suspended in 25 towns and cities in Batangas to keep students safely at home. Some schools resumed online classes and home learning that were in wide use at the height of the coronavirus pandemic, officials said.

Flights serving the eastern Sicilian city of Catania were halted after an eruption from nearby Mount Etna, local authorities said, bringing fresh travel troubles to the crisis-plagued Italian airport.

The 3,330 metre high volcano burst into action overnight on Sunday, firing lava and ash high over the Mediterranean island. The lava flow subsided before dawn, but ash was still coming from one of the craters.

Flights to and from Catania, a popular tourist destination, were set to remain suspended until 6am on Tuesday morning, the airport operator said in a statement, dashing hopes they could resume on Monday night.

Database with 2,400 prehistoric sites

The role of culture in human expansions: Large-scale collection of digital data summarizes the results of 150 years of research and can be used by amateurs and scientists alike.
Map of Human Expansion

Human history in one click: For the first time, numerous sites relating to the early history of mankind from 3 million to 20,000 years ago can be accessed in a large-scale database. Scientists from the research center ROCEEH ("The Role of Culture in Early Expansions of Humans") have compiled information on 2,400 prehistoric sites and 24,000 assemblages from more than 100 ancient cultures. The digital data collection is available for free to scientists and amateurs and was recently published in the journal PLoS ONE.

The research center is located at the University of Tübingen and the Senckenberg Society for Nature Research, sponsored by the Heidelberg Academy of Sciences and Humanities, and funded in part through the Union of German Academies.

ROAD, the "ROCEEH Out of Africa Database", represents one of the largest digital collections of information about archaeology, anthropology, paleontology and botany based on 150 years of research history, says Dr. Andrew Kandel, University of Tübingen. By joining information about cultural remains, human fossils, animal bones and plants into a unified geographical and chronological framework, the team created a tool that helps analyze the complex aspects of human evolution.
