May 5: Pu’u O’o, Before and After

Screencaps from Mick Kalber flyover videos April 28 and May 4(?) as noted by @ReelNewsHawaii on Twitter.

May 3: Earthquakes, Empty Pu’u O’o

Foggy/rainy weather had limited visibility, but the skies cleared May 3. A USGS overflight revealed the crater was completely drained:

At 10:30 AM, a magnitude-5 earthquake caused more of the crater to collapse, throwing up a cloud of pink ash.

Apr 30: Pu’u O’o Crater Collapse

The floor of Pu’u O’o collapsed in stages starting at 2PM in the afternoon and evening of April 30. Poor weather, fog and clouds obscured the view, but the thermal webcam positioned on Pu’u O’o’s  north rim captured it. Timelapse April 28-May 1:

This isn’t the first time it’s collapsed. Here’s a regular webcam timelapse movie of Pu’u O’o’s crater floor collapsing on March 5, 2011.

So there’s a chance the lava may return.
