A new array of seismometers provides a glimpse of what’s happening deep beneath this geologic fault. New data help explain why the north and south of the region are more seismically active than the middle.
When magma rises towards the surface gas bubbles start to form. Whether or not they can escape as the magma is rising affects how explosive the eruption will be.
It feels as if volcanoes in our region are going off at a high rate right now - but it’s reasonably normal activity for the “Ring of Fire” belt running around the Asia Pacific.
The Nov. 12 earthquake wasn’t centered on any known major faults in the Earth’s crust. In its wake, scientists will collect data to add detail to what they know about seismic activity in the area.

We have better maps of the moon than Earth’s newest continent, Zealandia. That’s about to change as an international expedition probes the vast undersea plateau of continental crust.
