Lava in Hawaii, seismic shaking in Alaska and underwater rumblings near Oregon. Scientists say it’s not the end of the world, but it’s definitely worth watching.

Mount Kilauea on Hawaii’s Big Island erupted for nine continuous hours on Wednesday, shooting fountains of lava reaching up to 1,200 feet at times. The volcano has erupted 28 times since last December.

Another explosive episode of Kilauea’s volcanic activity came and went Wednesday after Episode 28 of the ongoing eruption in Halemaumau Crater saw eight hours of high fountaining.

Kilauea is one of the most active volcanoes in the world, and this latest eruption once again demonstrates the geological dynamism of the Hawaiian archipelago.

According to Hawaiian Volcano Observatory, the north vent stopped around 1:20 p.m. The south vent did not open during this episode and was completely covered by new deposits. A cone has grown around the north vent, which has connected to the top of the surrounding cliff in some areas. Volcanic gas emissions have decreased since the pause.

KILAUEA (HawaiiNewsNow) - Episode 28 of the of the ongoing Halemaʻumaʻu eruption began at around 4:10 a.m. HST on Wednesday, July 9. Lava fountains are actively spewing upward of 150 feet into the air. Past episodes have produced lava fountains reaching 1,000 feet in the air.

Essentially, gas pistoning is a shallow, degassing-driven rise and fall of a lava surface. Often these pistons occur in narrow conduits — although they can happen in larger lava lakes and even in lava channels — and in bunches, as part of a series.
