Coverage of volcanic activity since March 22, 2021.

New technique could help predict volcanic eruptions years in advance

"...Scientists have developed a new satellite-data-based early warning technique that could one day be used to predict volcanic eruptions years before they take place, according to the results of a new study. Alongside providing advanced warning, the orbital data could help the scientific community figure out which volcanoes should be fitted with sensitive ground-based monitoring equipment. Volcanoes are among the most terrifying and spectacular sights to be found on our Blue Planet..."

Hidden magma pools pose eruption risks that we can't yet detect

"...Rooyakkers, who is lead author on the study and completed the work while at McGill University, compared the composition of the quenched magma, which had formed smooth volcanic glass, with rocks from an eruption from that same volcano, Krafla, in 1724. Before his study, scientists thought the shallow magma they'd drilled into had been emplaced after a series of eruptions in the 1980s. No one expected the hidden magma to be related to the 1724 eruption, so what Rooyakkers found was a surprise..."

Having Your Desalination and Eating It, Too Hakai Magazine

"...Residents of the parched, volcanic Canary Islands, a Spanish archipelago in the North Atlantic, have relied heavily on desalination to supplement their scant fresh water for the past 50 years. But there is growing evidence that plumes of waste brine from the hundreds of desalination plants on the islands are destroying seagrass along the coastline by reducing photosynthesis, and leaf and root growth. The waste brine—a toxic mix of concentrated seawater, acids, and biocides—also depletes oxygen in the seawater..."

Landslides: New early warning systems reduce false alarms

"...Many slopes in the Campania region are covered with layers of volcanic soil, the result of repeated eruptions over the course of millennia. As the impacts of climate change worsen, including the occurrence of very intense and short rainfall in localized areas, there is a growing need, especially in this and other Italian regions that are vulnerable to landslides, to understand the dynamics that induce such events more precisely and develop models that can predict them. When employed through adequate early warning systems, these tools can support decision-makers in adopting effective and efficient measures to protect people and the areas themselves from landslides..."

"...This image provided by the Icelandic Coast Guard shows a volcano on the Reykjanes Peninsula in southwestern Iceland on Saturday March 20, 2021. A long dormant volcano on the Reykjanes Peninsula flared to life Friday night, spilling lava down two sides in that area's first volcanic eruption in nearly 800 years. Initial aerial footage, posted on the Facebook page of the Icelandic Meteorological Office, showed a relatively small eruption so far, with two streams of lava running in opposite directions..."
