Reykjanes awaken

Hi all. I am an emergency photographer in Iceland and I have been documenting the thirteen eruptions we have had here on the Reykjanes peninsula on Icelands southwest corner for the past six years. I have done more than 130 trips to the area and documented the eruptions and their affects on the environment and community. It is partly self funded and relies on book sales, lectures, print sales etc as well as some funding from agencies and organizations. But getting the word out and promoting my work is an important part of the project and I hope I am not crossing any boundaries by posting about it here. I thought some of you might be interested in checking it out and also, there is an online store on my webpage and I recently published a book about the project in English. 😀🙏 This video, while perhaps a bit dramatic, kind of explains what I have been doing here.

Unzen, Japan

Was lucky to visit and work at the active dome of Unzen (Kyushu, Japan). The climb was done on May 16, 2026.

Please note that this part of the volcano is closed to the general public! Only researchers and authorities can go there after obtaining a permission. On the way back we met a couple of tourists which were absolutely unprepared for the hike but still sneaked behind the closed gates.

Xinantecatl

Also called "Nevado de Toluca", it's located in Toluca valley in Mexico, it reached 4680 m above sea level, which makes it the 4th highest formation in Mexico. It is also located in the ring of fire.

It has two small lakes in the crater callen Sun and Moon lakes, the crater is the result of the cone being completely destroyed 60,000 years ago, and the volcano has not had any kind of activity for 3,300 years.

Didn't see this one posted before so i thought I could share :)

Stromboli yesterday.

Taken from 290m viewing platform. Most activity occurred in the NE vent area with one main active vent with continuous spattering. A secondary vent activated occasionally. Central South vent area less active but also had occasional eruption :)

After reading the theory Mt Humphreys in Arizona possibly went through a lateral blast in the past like St Helens did, I created topographical representations of the two mountains

I'm not a volcanologist, I just found the structures of the two so similar and was interested by that. I understand Mt Humphreys structure could have been formed due to a landslide as well.

The images were created using USGS topographical data and python

Struggling to understand the geography of Krakatoa

Hoping someone can help me understand! I am making a powerpoint for my birthday about my favourite historical eruption and I'm struggling with the geography.

My understanding now is that Krakatoa is not a singular volcano? Instead, it is an island that rests over a large magma chamber and it houses 3 volcanoes: Rakata, Danan, and Perboewatan. After the eruption(s), the magma chamber collapses, creating the caldera and destroying... what? I read that it was Perboewatan that had erupted initially. Was it just that one? Or did all three go off?

I found a map of the islands how they are now with an outline of what it used to be prior to the 1883 eruption and it looks like Danan and Perboewatan are destroyed and Anak Krakatoa came up out of the water between the two, creating the 4 islands that exist today.

Is this the general gist of things? I don't know why I'm having such a hard time wrapping my head around this 😂 I have been reading so many different articles and none of them have been clear about this at all.

Thank you for any insight, I really appreciate it!

Has there ever been a case of a volcanic vent opening being caught on camera?

As in picturing the exact moment the ground cracks and lava/gases start spewing out.

Has it ever happened?

Kīlauea Eruption Update , Episode 47 of Kīlauea summit lava fountaining began at 3:27 p.m. HST today, May 14, and is ongoing.

This eruption is taking place within Kīlauea summit caldera in Hawai‘i Volcanoes National Park. Precursory lava flows began from the south vent at 2:57 a.m. this morning, May 14, and continued intermittently today from both the north and south vents.  Both vents are currently erupting, with low-level activity in the south vent while lava fountains at the north vent are currently about 65 feet (20 meters) high. National Weather Service forecasts low-level tradewinds today, which suggests that volcanic gas emissions and volcanic material may be distributed southwest of Halemaʻumaʻu. 
 
Fountaining episodes typically last 12 hours of less, but ash can remain in the air for longer depending on wind and weather conditions. Please stay aware of hazards and rely on official updates from USGS, National Weather Service, and Hawai’i Volcanoes National Park.

What are some volcanoes around the world that should probably get more attention? In terms of possible eruptions or danger to communities?
