NASA’s Ready-to-Use Dataset Details Land Motion Across North America – NASA
An online tool maps measurements and enables non-experts to understand earthquakes, subsidence, landslides, and other types of land motion. NASA is collaborating with the Alaska Satellite Facility in Fairbanks to create a powerful web-based tool that will show the movement of land across North America down to less than an inch. The online portal and … Read more
NASA Satellite Images Could Provide Early Volcano Warnings – NASA
Scientists know that changing tree leaves can indicate when a nearby volcano is becoming more active and might erupt. In a new collaboration between NASA and the Smithsonian Institution, scientists now believe they can detect these changes from space. As volcanic magma ascends through the Earth’s crust, it releases carbon dioxide and other gases which … Read more
5 Surprising NASA Heliophysics Discoveries Not Related to the Sun – NASA Science
5 min read 5 Surprising NASA Heliophysics Discoveries Not Related to the Sun With NASA’s fleet of heliophysics spacecraft, scientists monitor our Sun and investigate its influences throughout the solar system. However, the fleet’s constant watch and often-unique perspectives sometimes create opportunities to make discoveries that no one expected, helping us to solve mysteries about … Read more
Powerful New US-Indian Satellite Will Track Earth’s Changing Surface – NASA
Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure. We don’t always notice it, but much of Earth’s surface is in constant motion. Scientists have used satellites and ground-based instruments to track land movement associated with volcanoes, earthquakes, landslides, and other phenomena. But … Read more
Ongoing Venus Volcanic Activity Discovered With NASA’s Magellan Data – NASA
An analysis of data from Magellan’s radar finds two volcanoes erupted in the early 1990s. This adds to the 2023 discovery of a different active volcano in Magellan data. Direct geological evidence of recent volcanic activity on Venus has been observed for a second time. Scientists in Italy analyzed archival data from NASA’s Magellan mission … Read more

Bogota, Colombia CNN — Hundreds of families in Colombia are facing a choice: abandon their homes and livelihoods, or face the devastation of a predicted volcanic eruption in the coming weeks. The Nevado del Ruiz volcano, one of Colombia’s highest peaks, sits in a densely populated farming area and is infamous for claiming the lives … Read more
La Palma: drone footage reveals massive river of lava – video
Drone footage surveying the Cumbre Vieja volcano shows a massive river of thick lava flowing towards the Atlantic Ocean. Approximately 7,500 people have been forced to leave their homes since the Cumbre Vieja began erupting more than a month ago. Scientists say the eruption could go on for three months Source link
Lightning flashes over La Palma volcano as lava engulfs buildings – video
The red-hot eruption from the volcano on the Spanish island of La Palma was accompanied by flashes of lightning early on Saturday. A study published in 2016 by the journal Geophysical Research Letters found lightning can be produced during volcanic eruptions because the collision of ash particles creates an electrical charge Source link
Drone footage shows path of devastation from La Palma’s Cumbre Vieja volcano – video
Drone footage captures the devastation wrought by the Cumbre Vieja volcano, which has been ejecting ash, smoke and lava over the Canary island of La Palma for more than 10 days. Since erupting on 19 September, the volcano has destroyed more than 800 buildings, as well as banana plantations, roads and other infrastructure. About 6,000 people … Read more
