A study in China identified recurring patterns in seismic, magnetic and ionospheric data before numerous major earthquakes. The researchers say these “seismo-ripples” could provide estimates of an earthquake’s magnitude, location and timing, but the method remains limited by monitoring coverage, especially for earthquakes beneath the ocean.
Researchers used seismic signals produced when thunder’s sound waves enter the ground to image the shallow subsurface beneath an urban karst setting. The method identified several previously undetected weak zones, some of which matched surface deformation and independent underground surveys.
A paper in the Journal of Applied Volcanology catalogs 18 common misconceptions about volcanoes and eruptions, from volcanic ash and smoke to forecasts and “supervolcanoes.” It also examines seven case studies where incorrect information spread during events at volcanoes including Mount Agung, Kīlauea and Taal.
