The document discusses the Fukushima nuclear accident and draws analogies to volcanic activity. It poses a series of questions about how chemicals released during the accident, such as sulfur-35 and cesium-137, could interact with volcanic gases and rocks. Specifically, it inquires whether sulfur-35 could impact volcanic structures or transport radioactive material to water/soil near volcanoes. It also asks if cesium-137 deposition is being examined in volcanic soils and sediments, and if uranyl peroxide could disperse uranium in submarine volcanic environments. Overall, the document suggests the Fukushima releases could exacerbate chemical reactions within the Earth and warrant further geological study.
