Kilauea 2018 East Rift Zone Eruption

I decided to split the show notes for each eruption into their own post. Just because it was getting a little long. This is meant to be read and watched along with or after listening to S04E05 of Borealis Meditation Podcast (hence the lack of text). 

Kilauea Volcano!

Summit Overflow (Late April)

Drone footage and time lapse of Summit Collapse

Lower East Rift Zone (Puna)

Here are a few maps for some context on the geography of the eruption:

Major features on Kilauea Volcano and landmarks. The summit collapse and overflow shown above happened within Halema’uma’u crater (circled) which is in tern within the summit caldera. Pu’u ‘O’o has been the center of activity since 1983, and I mentioned Hwy 130 in terms of the earthquakes going down the rift. The east rift zone is highlighted on the map showing it going all the way out to Kapoho and it continues underwater as well.
This is an older map but you can see the areas of newish lava over the last ~200 years. Lava zones correspond to levels of hazard and have an impact on if you can get insurance and how expensive it is, and therefore the prices of land. When people ask “why do people live on the rift zone” the answer is that, simply land is expensive in Hawaii and the higher the risk the cheaper the land. Lava zone 1 = on a vent or rift zone, Lava zone 2 = down slope from a vent or rift zone. These are the highest levels of risk in terms of lava. The areas covered in this eruption were all lava zone 1 and 2

Pu’u ‘O’o

Time lapse showing the filling of Pu’u O’o crater with the perched lava pond in March and early April. Below is the late April collapse of Pu’u O’o. Now remember I said the weather was super shit so the thermal camera is what was used to “see” the collapse. You might have to loop it a few times but you can see where the lava lake was at about the same level and then the drop to an open vent.



Below the collapse is an over flight and 3D model. So remember the earlier lava pond all high up in the crater? Look at that change!!!!

Down the rift zone…..

This is the final extent of the fissure eruption lavas show in the video of before and after above. The large area in the upper right is where Kapoho, Kapoho Tidepools, and Vacation land were.
This is a map released around the end of the eruption. You can see the former coast line plotted along with the fissures and landmarks.
for comparison here is what the lava flow areas and active flow field looked like before this eruption. You can see the communities on this one that were covered

That is what I have for the Kilauea 2018 major activity.
