A Comment on... Volcanoes in a Changing Global Climate It is highly speculative at present to predict how global climate change will transform the science of volcanology. Yet it is important that we begin to anticipate how the impacts of volcanoes will change, as population and precipitation patterns adjust to climate change during the 21st century.  |

Eruptive Event Caught Red-Handed Researchers know that, in general, mid-ocean ridges are the site of periodic eruptive events that create new seafloor. At the East Pacific Rise, determining the seismic characteristics that lead up to eruptions could help researchers predict when and where along the trench future events are likely to occur.  |
