On 27 June 2014, Puʻu ʻŌʻō Crater of the Kīlauea Volcano in Hawaii started a new lava flow, beheading a previous flow. The flow headed northeast through the Puna district towards Pāhoa, passing right by the Kahoe Homesteads subdivision. At the moment the flow is stalled short of Apa`a Street in Pāhoa, but it could resume and ultimately cut the town in half. What to do? [more inside]
The Sound So Loud That It Circled the Earth Four Times. "It was 10:02 AM local time when the sound emerged from the island of Krakatoa, which sits between Java and Sumatra in Indonesia. It was heard 1,300 miles away in the Andaman and Nicobar islands ('extraordinary sounds were heard, as of guns firing'); 2,000 miles away in New Guinea and Western Australia ('a series of loud reports, resembling those of artillery in a north-westerly direction'); and even 3,000 miles away in the Indian Ocean island of Rodrigues, near Maldives ('coming from the eastward, like the distant roar of heavy guns.'1) In all, it was heard by people in over 50 different geographical locations, together spanning an area covering a thirteenth of the globe."

The Vestmannaeyjar Archipelago, off the south coast of Iceland, was first settled in 874 AD. Heimaey, the only populated island, was home to both a center of the Icelandic fishing industry, and a volcano which had never erupted during nearly a millennium of continuous human settlement. Then, in 1973, all hell broke loose. [more inside]

On 10 April 1815, Tambora produced the largest eruption known on the planet during the past 10,000 years. As described in Gillen D'Arcy Wood's new book, the explosion was only the first dose of Tambora's destructive power. In terms of its enduring presence in folklore, as well as its status in the scientific literature, 1816’s cold summer was the most significant meteorological event of the nineteenth century. After the tsunami and famine came cholera, opium, and failed Arctic expeditions. [more inside]
Vulcan Point in the Philippines is the world's largest island within a lake (Main Crater Lake) that is situated on an island (Volcano Island, aka Taal Island) located in a lake (Lake Taal) within an island (Luzon). It also happens to be one of the cones of the active Taal Volcano, so Vulcan Point is also the world’s largest volcano in a lake (Main Crater Lake) on a volcano (Taal Volcano). And Main Crater Lake also happens to be the largest lake on an island (Volcano Island) in a lake (Lake Taal) on an island (Luzon). Got that? If not, here's a series of images that provides a handy guide to the location of the nested parts of this complex volcano, which is a beautiful place, but still very much active.
Scientists make volcanic lightning in a laboratory "A team of researchers at Germany’s Ludwig Maximilian University led by Corrado Cimarelli built an experiment that allowed them to study the conditions that trigger lightning at the base of the eruption plume."
In 1831, the Mediterranean south of Sicily began to boil and bubble, and before long a volcanic island appeared, in full eruption. The English were the first to lay claim to the new island, naming it Graham Island, for James Graham, First Lord of the Admiralty. Then the Kingdom of the Two Sicilies laid claim to the island, removing the Union Jack and naming the island Ferdinandea, after King Ferdinand II. The next nation to claim the island was France, though initial French interest was in the geology of the newly emerged island (Google translation of French text, much from geologist Constant Prévost). France's choice of names was practical, Île Julia, as the island was formed in July. Spain also tried to lay claim to the newly formed island, setting the stage for a grand four-way dispute over its sovereignty, but before a single shot could be fired over its possession, geology rapidly had the last word on the matter. Graham Island/ Ferdinandea/ Île Julia crumbled in on itself and all but disappeared by the end of the year. [more inside]

After nearly 200 years of rest, Mount Tambora is rumbling again and spewing ash. The last eruption of Mount Tambora was in 1815 and at the time was the largest eruption in the world since 180 AD. The massive amount of volcanic ash kicked into the stratosphere (around 160 cubic kilometers of ejecta were released) cooled Earth's temperature by over a degree Fahrenheit and caused "The year without a summer". In comparison, the 1980 eruption of Mount Saint Helens released around 1 cubic kilometer of ejecta.

Oh cool, a thermal video of a Hawaiian volcano. More cool, but non thermal, video of another volcano in Hawaii. Another awesome geographical happening in you know where. Wow, the place is a hotspot for shield volcanoes, even has its own observatory.
On May 18th, 1980, thirty years ago today, at 8:32 a.m., the ground shook beneath Mount St. Helens in Washington state as a magnitude 5.1 earthquake struck, setting off one of the largest landslides in recorded history - the entire north slope of the volcano slid away. As the land moved, it exposed the superheated core of the volcano setting off gigantic explosions and eruptions of steam, ash and rock debris. The blast was heard hundreds of miles away, the pressure wave flattened entire forests, the heat melted glaciers and set off destructive mudflows, and 57 people lost their lives. A photo-essay.
Sean Stiegemeier decided that he had seen enough terrible pictures of the eruption of the Icelandic volcano, Eyjafjallajökull, that he flew to see it on his own. [more inside]

In the last two weeks, [NYT] more than 100 mostly tiny earthquakes a day, on average, have rattled a remote area of Yellowstone National Park in Wyoming, putting scientists who monitor the park’s strange and volatile geology on alert. The quake zone, about 10 miles northwest of the Old Faithful geyser, has shown little indication of building toward a larger event, like a volcanic eruption of the type that last ravaged the Yellowstone region tens of thousands of years ago. Don't rest too easily, though: new studies of the plumbing that feeds the Yellowstone supervolcano shows the plume and the magma chamber under the volcano are larger than first thought and contradicts claims that only shallow hot rock exists. For more info, check out this exhaustive site that tracks Yellowstone tectonic activity and details a possible supervolcano event. [previously]

Framed by a circle of clouds, this is a stunning illustration of Nature's powerful force. A plume of smoke, ash and steam soars five miles into the sky from an erupting volcano. The extraordinary image was captured by the crew of the International Space Station 220 miles above a remote Russian island in the North Pacific.
After months of pre-eruptive activity, Alaska's Mount Redoubt has erupted 6 times since Sunday night. Telegraphing its eruption with massive shallow earthquake activity in the range of 26 earthquakes every 10 minutes, the volcano, located around 100 miles southwest of Anchorage, spewed an ash column 10km high, and is expected to continue erupting for weeks or months. The last time this massive volcano erupted in 1989 a commercial airliner was caught in the ash column, causing the engines to seize and the plane to lose two miles of altitude before the engines were restarted. That eruption, which lasted for 5 months, produced this spectacular photo. Follow this amazing event at the Alaska Volcano Observatory. [more inside]

On June 8, 1783, the volcano Laki in south Iceland tore open a 16-mile fissure that erupted over nine cubic miles of lava. Not only would this eruption kill over 50% of Iceland's livestock population, leading to famine which killed approximately 25% of the population; its effects were felt the world over, with flourine, sulfur dioxide, ash, sand and drastically cooled tempertaures from the blotted-out sun reaching as far afield as North America and Africa. The eruption lasted for nearly eight months. And from the day the eruption began, a humble priest named Jón Steingrímsson would make his mark in history. [more inside]

An erupting stratovolcano poses numerous hazards for nearby habitation, but none nearly so terrifying and deadly as the pyroclastic flow. Pyroclastic flows, comprised of tons of superheated sulfuric gases, particulate rock materials and ash, can reach temperatures of 1,830 °F and travel at alarming speeds up to 450mph. Convection of materials within the clouds causes them to become a suspension, fluidizing and thundering noxiously across the surrounding landscape for miles, in some cases even uphill or across open water. Wherever these clouds come in contact with humans the result is catastrophe, as the residents of Herculaneum and St. Pierre, Martinique learned within minutes of the eruptions of Vesuvius in 79AD and Pelee in 1902-- both towns were overwhelmed by pyroclastic clouds, igniting all flammable materials and incinerating and suffocating the inhabitants. None survived Herculaneum, while just two of St. Pierre's 26,000 survived, one of whom was a prisoner condemned to death and awaiting his execution in a dungeon cell. Despite their incredible capacity for violence, pyroclastic flows are also capable of producing mesmerizing, awe-inspiring beauty.
