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. |
