Volcano Watch — It’s All About Perspective: How to Interpret an Interferogram
Volcano Watch is a weekly article and activity update written by U.S. Geological Survey Hawaiian Volcano Observatory scientists and affiliates. Today's article is by Tyler Paladino, a Postdoctoral Fellow with the U.S. Geological Survey. Panels A and B show what an interferogram would look like for a simple expanding spherical magma chamber from an ascending and descending orbital perspective. The star shows the true center of the inflating magma source. The arrow and bar denote satellite flight direction and look direction respectively. Each fringe represents approximately 1.55 cm. Panels C and D show the same event in a cross-section view.
Perspective: California’s Coastal Challenges Amid Climate Change
Maintaining coastal sustainability will require a unified, whole-of-society response. The report calls on research institutions, urban planners, policy makers, and community organizations to come together to address threats like habitat loss, saltwater intrusion, and risks to infrastructure. The authors hope to foster collaboration on innovative policies for coastal development, conservation strategies, and risk management. To ensure California’s coastal zones remain viable, the report encourages community-level action and policy reforms that address these challenges head-on. This includes expanding research into how ecosystems respond to stressors, identifying sustainable land-use practices, and implementing protective measures that build climate resilience. Although the challenges may
