Volcanic Explosion (Video Credit: USGS Hawaiian Volcano Observatory).
The Big Island is an active island indeed! A rock fell from the east rim of Kīlauea within the Halema'uma'u Crater over the weekend. The rock fall caused an impact in the lava lake which generated an explosion around 2:17pm on Jan. 2. The HVO webcam caught the explosion on video.
An additional rockfall took place early on Monday morning (Jan. 4) which generated another small explosion within the crater. A rising gas plume rose from the surface of the lava lake, which was visible by a HVO webcam.
Tuesday morning (Jan. 5) there was some activity within the lava lake and it had risen slightly. Personnel with HVO stated that the lava lake was approximately 92 feet below the crater floor.
