Volcanic activity worldwide 21 Jul 2014: Kilauea

Monday Jul 21, 2014 21:00 PM |

Perhaps the most interesting feature in the new crater at Puʻu ʻŌʻō is the pit formed on the southern side of the crater floor. There, a small lava pond roughly 10 m (~30 ft) across has been sporadically overflowing and sending lava toward the deeper central part of the crater. View is to the south.
Perhaps the most interesting feature in the new crater at Puʻu ʻŌʻō is the pit formed on the southern side of the crater floor. There, a small lava pond roughly 10 m (~30 ft) across has been sporadically overflowing and sending lava toward the deeper central part of the crater. View is to the south.
Kilauea (Hawai'i): Kīlauea continued to erupt at its summit and within the East Rift Zone, and gas emissions in both areas remained elevated. There was no significant change in tilt recorded at the summit, and the lava lake level was relatively steady over the past week leveling at ~30m (98ft).

At the middle East Rift Zone, lava flows continued to erupt from the northeast flank of Puʻu ʻŌʻō cone, spreading to the northeast. The June 27th breakout continued to spread toward the northeast in two main lobes, reaching about 2km (1.2m) from the vent on the northeast flank of Puʻu ʻŌʻō. Small lava ponds were present within the two southeastern pits in the crater floor, and glow above the other two pits indicated lava was at least close to the surface there as well.

The most recent sulfur-dioxide emission-rate measurement was 500 tonnes per day (from all East Rift Zone sources) on July 3, 2014; emission rates have typically ranged between 150 and 450 t/d since July 2012.
