Recent Volcanic Activity in Hawaii, March 9th-24th

As of March 10th, the East Rift Zone eruption  had a lack of activity.

The video link above is from March 5th, but it is a very interesting look at the Kilauea crater collapsing.

The Kamoamoa fissure eruption was probably the most exciting thing Hawaii has seen recently. These pictures show the thickness of the flow produced by the eruption.

Since March 9th, the end of the Kamoamoa fissure eruption, no lava has been erupted on the east rift zone. The floor of Pu`u `O`o is still filled with rubble, and there is no active lava in the area. The summit of the mountain has been active this week, as the inflation and deflation of the lava lake in the Halema`uma`u Overlook vent has caused it tto disappear.

This week, some small rock falls have also been observed. The volcanic gas emissions have decreased over this past week but still remain high, resulting in high concentrations of sulfur dioxide downwind, from March 16th to 18th.

Two earthquakes were also felt beneath the Hawaii island this week, one on the 18th and the other on the 20th.

  1. One question. Why did you not cover the most exciting time period: the Kamoamoa fissure eruption?

    I don’t quite understand what you are trying to say in the paragraph about Halema’uma’u…
