Pele's Wrath

The island of Hawaiʻi, the largest of the chain that comprises our 50th state, is built from five separate shield volcanoes that erupted somewhat sequentially, one overlapping the other. [Wikipedia] 

The diagram (from another Wikipedia page) shows the United States Geological Survey hazard mapping for the island.  The lowest numbers correspond with the highest hazard levels.  The various volcanoes that comprise the island are shown below, listed below from oldest to youngest:


·       Kohala – dormant
·       Mauna Kea – dormant
·       Hualālai – active
·       Mauna Loa – active, partly within Hawaiʻi Volcanoes National Park
·       Kīlauea – active: has been erupting continuously since 1983; part of Hawaiʻi Volcanoes National Park

Earlier this month, a strong earthquake on the island was followed by increased eruptive activity from Kilauea.  To-date, dozens of homes have been destroyed and Hawaii Civil Defense have reported 2,000 people evacuated from their homes, away from the path of the flowing lava.  Hollywood-like scenes of devastation have dominated the nightly news, including images of people fleeing the irresistible rivers of fiery lava while making their way through steaming cracks that opened in neighborhood lawns and roadways.   

Officials warn of explosive eruptions of steam that would lift stone projectiles and ash into the air, should the lava reach subterranean aquifers. They stress that nobody can predict how long nor how extensive the eruption will be.  For now, they move people as far as possible for the danger as possible, though the relentless earthquakes and the threats of ashfall and acid rain remain.

Mauna Loa, the largest exposed (e.g., above the ocean’s surface) volcano in both mass and volume, has historically been considered the largest volcano on Earth.  It dominates the profile of Hawaii’s “Big Island,” and, although it has erupted in the past, it has been decades since it last showed its awesome power.  In what amounts to a sort of “worst case scenario” in the latest series of events, some scientists fear the increased activity at Kilauea will “awaken the sleeping giant” Mauna Loa and trigger a larger eruption.  Obviously they’re not talking a Mt. St. Helens-like event (St. Helens is a composite volcano, noted for explosive eruptions), but the lava flows from the last (1984) eruption of Mauna Loa came within four miles of Hawai’i’s largest city, Hilo.

Volcanism was obviously a huge part of the culture of the ancient inhabitants of the Hawaiian islands.  They gave the name “Pele” to the goddess of fire, wind and lightning and credited her (accurately so) with creating the islands on which they lived.  Following the events of the last week, many residents of Hawaii are wondering if perhaps the increased activity at Kilauea is, perhaps, a response by Pele to something they did (or didn’t do).

Somewhat tongue-in-cheek, a 21st Century reporter provided the following background to a news story (also the source of the photo) about the latest eruptive activity. But he found that the people he spoke with take ancient legends very seriously.

Residents near the lava zone on Hawaii’s Big Island having been leaving Ti leaves and flowers in front of their homes and near the cracks on the ground as an offering to the fiery volcano goddess Pele in hopes she will spare them from destruction.

“Scientists and experts have tried to predict what’s going to happen but they’ve been wrong,” resident Shannon Malina told Fox News Tuesday. “We are in (Pele’s) hands now. She’s coming back.”  Malina, who has been living in a Red Cross shelter in Pahoa, was forced to evacuate her home four days ago because of a volcanic eruption spewing bubbling lava and swallowing up residential neighborhoods. She believes it’s the work of Pele, who is coming back to right the wrongs of humanity…

Several people on the island in recent days told Fox News they believe the volcanic instability rocking the Big Island is a warning from Pele…. Even as she wept over the destruction, resident Linda Jones told Fox News, “Madame Pele: I have love and respect.”

So just who is this all-powerful Pele? It depends on who you ask.

Pelehonuamea, or Pele as she is more commonly known, is the goddess of fire, lightning, wind and volcanos. Passionate and moody, legend has it that she lives at the summit on Kilauea. Depending on which version of the story is told, Pele spent her most of her life locked in fierce feuds with family members and was prone to epic jealous outbursts that usually ended with her burning down everything in her path... [Sounds just like what’s happening on Hawai’i now.]

“No one said Pele was nice,” Malina says with a little laugh. “But she’ll protect her children, I know she will.”

The news report includes the following statement from a University of Hawaii language professor named Kaliko Baker. 

“Pele the goddess and the Pele the lava are one in the same.  It’s important to know that Pele is as natural to us, Hawaiians, the aboriginals of this island, as the wind that blows, as the ocean that crashes on the shores, as the lava that flows out of the volcano. It’s our norm and when Pele comes we just move because she’s got the right of way.”

In the case of volcanoes and lava flows, this is exactly the appropriate course of action for any human society.  Impacts from storms and floods can be mitigated.  Earthquake damage can be fixed and sometimes minimized by better design. But when faced with a wall of 2,200 degree liquid rock cascading down a slope toward you, there is no other choice than to “get out of the way.”

The lesson for the residents of Hawaii—a lesson they have learned over centuries of experience living under the threat of volcanic activity—is that human settlements have no business impeding the wrath of Pele.  Planning tools like Lava Flow Hazard Zone maps and other locational restrictions try to limit the impact of volcanic activity on communities in the state, but as we’ve seen in the last week, it’s not perfect.   

Even so, having enough respect for nature—or Pele, if you choose—to inform and modify our activity is critical to human survival.
