Ongoing inflation and crater floor uplift at Pu‘u ‘Ō‘ō
 

 

Over the past month, monitoring instruments have recorded a sharp inflationary trend at Pu‘u ‘Ō‘ō (see https://volcanoes.usgs.gov/volcanoes/kilauea/monitoring_deformation.html, scroll to bottom of page). Accompanying this inflation, the floor of Pu‘u ‘Ō‘ō crater has been uplifted and lava intermittently poured onto the crater floor. This animated GIF shows the uplift over five days last week (click on image above to see the animation), with the floor uplifting several meters (yards). Previous episodes of inflation and crater floor uplift in June 2014 and May 2016 resulted in lava erupting from new vents on Pu‘u ‘Ō‘ō. The current activity is similar to these previous patterns, indicating a higher likelihood - but not a guarantee - of upcoming changes at Pu‘u ‘Ō‘ō.
