Volcano Watch: Pele, Lono and Hi驶iaka remind us of nature鈥檚 power
The summit region of Kilauea experienced tephra fallout and a Kona low storm this past week. Cleanup, recovery, and regrowth is ongoing. These processes are natural and have been recognized and embodied in Native 91直播an oral traditions about Pele, Lono and Hi‘iaka.
Kilauea and 91直播’s other active volcanoes are ever-changing landscapes. From summits to coastlines, lava flows downslope to resurface land and add acreage where it enters the ocean. Lava fountains blanket areas downwind with pohaha, fallout, called tephra. As magma moves beneath the surface, it can cause ground cracks or collapsed areas such as craters to form on the ground above. Native 91直播ans attribute active volcanic processes to Pelehonuamea (Pele) — the creator of land.
The 91直播an Island chain, located in the middle of the North Pacific Ocean, is susceptible to storms that approach from various directions, including hurricanes, cyclones, and Kona low storms. These weather systems and accompanying wind, rain, and ocean surges, can topple trees, cause flooding and erosion, and cover the summits of Mauna Kea and Mauna Loa — the tallest volcanoes on the Island of 91直播 — with snow. Native 91直播ans say that rains, winds, thunder and lightning are the works of the elemental force Lono, who brings fertility to the land.
Volcanic eruptions and storms can completely transform landscapes, but natural recovery begins soon afterward. Where vegetation was damaged by new volcanic deposits or storms, new growth quickly begins. When vegetation is completely destroyed or buried, spores and seeds landing in these areas begin the processes of slowly restoring vegetation. Native 91直播ans attribute these actions to Hi‘iaka as she begins to re-green the land.
Native 91直播an oral traditions recorded interactions between Pele, Lono, and Hi‘iaka in the past, and we continue to see their interactions today. Last week, Pele dramatically appeared at the summit of Kilauea with a heavy fall of pohaha on March 10, followed by a wildly enthusiastic Lono a few days later … and now, Hi‘iaka is present in recovery.
During episode 43 of lava fountaining at the summit of Kilauea on March 10, the area northeast of Kaluapele o Kilauea (the summit caldera) was blanketed with tephra fallout from lava fountains that reached up to 1770 feet (540 meters) high. 91直播 Volcanoes National Park and portions of Highway 11 were temporarily closed due to the hazardous conditions created and to allow for the fallout to be cleared from roadways.
Several days later, a Kona low storm arrived, bringing days of wind and rain that flooded areas, knocked down trees and other vegetation, and blew parts of roofs off. Roads were temporarily blocked and power remains unavailable in some areas.
Recovery for the people living on these landscapes today has a different meaning now compared to the past because we are largely reliant on infrastructure such as power and transportation. When these resources are impacted by natural events, our daily lives are affected. But there are steps you can take to be aware of the hazardous natural events that may affect you here and make preparations where possible.
If you live in an area in close proximity of volcanic activity, maintain an awareness of the status of our active volcanoes by subscribing to receive notices from the USGS 91直播an Volcano Observatory (volcanoes.usgs.gov/vns/).
Check the National Weather Service Honolulu Forecast Office for updates on local weather (www.weather.gov/hfo/). Subscribe to receive notifications regarding real-time hazards, including severe weather and road closures, from the 91直播 County Civil Defense Agency (tinyurl.com/3b35jeeh).
The USGS 91直播an Volcano Observatory has forecast the start of episode 44 of ongoing episodic lava fountaining in Halema‘uma‘u for sometime between April 1-10. Living in such a dynamic place as the Island of 91直播, it’s important to try and be aware and prepared for the natural events that affect us.
Nature will continue to reshape the land in 91直播, and these recent events are a reminder of how impactful such natural events can be.
Volcano activity updates
Kilauea has been erupting episodically within the summit caldera since Dec. 23, 2024. Its USGS Volcano Alert level is WATCH.
Episode 43 lava fountaining happened for just 9 hours on March 10. Summit region inflation since the end of episode 43 indicates that another fountaining episode is possible, with models suggesting that episode 44 could begin between April 1-10. No unusual activity has been noted along Kilauea’s East Rift Zone or Southwest Rift Zone.
Mauna Loa is not erupting. Its USGS Volcano Alert Level is at NORMAL.
Two earthquakes were reported felt in the 91直播an Islands during the past week: a M2.9 earthquake 14 km (8 mi) NNE of 91直播an Ocean View at -1 km (0 mi) depth on March 12 at 8:54 p.m. and a M4.4 earthquake 13 km (8 mi) ESE of Pahala at 29 km (18 mi) depth on March 12 at 5:16 p.m.
