New USGS Data Release — Crater geometry data for Puʻuʻōʻō, on Kīlauea Volcano’s East Rift Zone, in May 2018

The USGS recently published a data release that includes a three-dimensional model of Puʻuʻōʻō, on Kīlauea's East Rift Zone, and the collapse crater, constructed from aerial thermal images collected on 11 May 2018.  Structure-from-motion processing was used to create the model from the sequence of oblique images, and ground control using kinematic GPS was used to georegister the model.

Volcano Watch — What’s that (seismic) noise?

The USGS Hawaiian Volcano Observatory (HVO) uses dozens of seismometers to locate individual earthquakes and identify signals that are related to faulting and magma movement within our volcanoes.
