Wet and wild: There's lots of water in the world's most explosive volcano
Conditions inside the Shiveluch volcano include roughly 10%-14% water by weight (wt%), according to research from Washington University in St. Louis. Most volcanoes have less than 1% water. For subduction zone volcanoes, the average is usually 4%, rarely exceeding 8 wt%, which is considered superhydrous. (2021-01-22)

Hawai'i researchers kept the data flowing during crisis response on K?lauea
The summer 2018 eruption of K?lauea Volcano on the Island of Hawai'i was one of the most significant in the volcano's history, collapsing a large portion of the summit caldera, erupting massively from its flank and triggering a magnitude 6.9 earthquake in the process. Through it all, scientists at the Hawaiian Volcano Observatory were installing new geophysical stations, processing data and making real-time reports to local authorities and neighborhoods.

Cascading events led to 2018 Kīlauea volcanic eruption, providing clues for forecasting
The 2018 eruption of Kīlauea Volcano was one of the largest volcanic events in Hawai'i in 200 years. This eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study published in Nature Communications by earth scientists from the University of Hawai'i at Mānoa and U.S. Geological Survey.

Crystals reveal the danger of sleeping volcanoes
Most active volcanoes on Earth are dormant and are normally not considered hazardous. A team of volcanologists from the University of Geneva has devised a technique that can predict their devastating potential. The scientists used zircon, a tiny crystal contained in volcanic rocks, to estimate the volume of magma that could be erupted once Nevado de Toluca volcano (Mexico) will wake up from its dormancy. Up to 350 km3 of magma are currently lying below. (2020-11-05)

Using a volcano's eruption 'memory' to forecast dangerous follow-on explosions
Stromboli, the 'lighthouse of the Mediterranean', is known for its low-energy but persistent explosive eruptions, behaviour that is known scientifically as Strombolian activity. Occasionally, however, more intense and sudden explosions occur, most recently in July and August last year (2019). These are known as 'Strombolian paroxysms'. During such events several of Stromboli's craters are active simultaneously and much greater volumes of pyroclastic materials are erupted than is usual for the volcano. (2020-10-28)

Results from the DEFINE-FLOW study reported at TCT Connect
A new observational study of deferred lesions following combined fractional flow reserve (FFR) and coronary flow reserve (CFR) assessments found that untreated vessels with abnormal FFR but intact CFR do not have non-inferior outcomes compared to those with an FFR greater than 0.8 and a CFR greater than or equal to two when treated medically.

Optical seismometer survives "hellish" summit of Caribbean volcano
The heights of La Soufrière de Guadeloupe volcano can be hellish, sweltering at more than 48 degrees Celsius (120 degrees Fahrenheit) and swathed in billows of acidic gas.

Texas cave sediment upends meteorite explanation for global cooling
Texas researchers from the University of Houston, Baylor University and Texas A&M University have discovered evidence for why the earth cooled dramatically 13,000 years ago, dropping temperatures by about 3 degrees Centigrade. The evidence is buried in a Central Texas cave, where sediment has preserved unique geochemical signatures from ancient volcanic eruptions. (2020-07-31)

A new chemical analysis upends conventional explanation for global cooling
Scientists have long known the earth cooled dramatically about 13,000 years ago, and the most likely explanation has been that it was caused by a massive object slamming into earth from space or bursting in the atmosphere. But now researchers have reported new evidence for another, more likely explanation - the eruption of a volcano on what is now the European continent, upending thinking about an event that shaped future evolution. (2020-07-31)

Scientists reveal an explosive secret hidden beneath seemingly trustworthy volcanoes
An international team of volcanologists working on remote islands in the Galápagos Archipelago has found that volcanoes which reliably produce small basaltic lava eruptions hide chemically diverse magmas in their underground plumbing systems - including some with the potential to generate explosive activity. These volcanoes might undergo unexpected changes to sudden such activity in the future. (2020-07-28)

Photos may improve understanding of volcanic processes
The shape of volcanoes and their craters provide critical information on their formation and eruptive history. Techniques applied to photographs -- photogrammetry -- show promise and utility in correlating shape change to volcanic background and eruption activity. (2020-07-20)

Alaskan volcano linked to mysterious period with extreme climate in ancient Rome

Eruption of Alaska's Okmok volcano linked to period of extreme cold in ancient Rome
An international team of scientists and historians has found evidence connecting an unexplained period of extreme cold in ancient Rome with an unlikely source: a massive eruption of Alaska's Okmok volcano, located on the opposite side of the Earth. A new study uses an analysis of tephra (volcanic ash) found in Arctic ice cores to link this period of extreme climate in the Mediterranean with the caldera-forming eruption of Alaska's Okmok volcano in 43 BCE. (2020-06-22)

Climate change and the rise of the Roman Empire and the fall of the Ptolemies
The assassination of Julius Caesar on the Ides of March in 44 B.C.E. triggered a 17-year power struggle that ultimately ended the Roman Republic leading to the rise of the Roman Empire. To the south, Egypt, which Cleopatra was attempting to restore as a major power in the Eastern Mediterranean, was shook by Nile flood failures, famine, and disease. A new study reveals the role climate change played in these ancient events. (2020-06-22)
