New Study Reveals Why Easter Island's Statues Are Positioned Along the Coast

From the fate of its once vibrant population to the origins of its moai statues, Easter Island is rife with mystery. As Ars Technica reports, a team of scientists may have answered one question related to the famous heads located on the island off the coast of Chile: Why were they placed in some spots on the island and not others?

According to their study in the journal PLOS One, ancient islanders positioned the moai around precious sources of fresh water. This theory may seem confusing if you're familiar with the island's layout: Almost all of the stone artifacts are located along the coast.

But the study authors write that the statues are markers for hidden water sources. On Easter Island, and other volcanic islands, volcanic tubes carry fresh water from underground into the ocean, creating patches of drinkable water surrounded by the salty sea. Fresh water is a limited resource on the island, and its inhabitants likely depended on these water pockets to survive.

When researchers pinpointed these off-shore water sources, they found either moai statues or the platforms that were used to hold them next to each site. And this wasn't a result of islanders placing moai randomly along the coast: Further analysis revealed that the presence of a freshwater patch was the strongest indicator of where an Easter Island head would be.

Easter Island's scant natural resources are part of the mystery that surrounds its ancient people. At its peak, the Easter Island may have sustained a population of 17,500, and the complex social structure of its inhabitants enabled them to achieve great things, such as carving and transporting 81-ton statues around the island. Though we now have an idea of why the moai ended up where they did, the question of how they got there is still up for debate.

Did the Northern Lights Play a Role in the Sinking of the Titanic? A New Paper Says It’s Possible

The sinking of the RMS Titanic on April 15, 1912, is the most famous maritime disaster in history. The story has been retold countless times, but experts are still uncovering new details about what happened that night more than a century later. The latest development in our understanding of the event has to do with the northern lights. As Smithsonian reports, the same solar storm that produced an aurora over the North Atlantic waters where the Titanic sank may have caused equipment malfunctions that led to its demise.

Independent Titanic researcher Mila Zinkova outlines the new theory in a study published in the journal Weather. Survivors and eyewitnesses from the night of the Titanic's sinking reported seeing the aurora borealis light up the dark sky. James Bisset, second officer of the ship that responded to the Titanic's distress calls, the RMS Carpathia, wrote in his log: "There was no moon, but the aurora borealis glimmered like moonbeams shooting up from the northern horizon."

Zinkova argues that while the lights themselves didn't lead the Titanic on a crash course with the iceberg, a solar storm that night might have. The northern lights are the product of solar particles colliding and reacting with gas molecules in Earth's atmosphere. A vivid aurora is the result of a solar storm expelling energy from the sun's surface. In addition to causing colorful lights to appear in the sky, solar storms can also interfere with magnetic equipment on Earth.

Compasses are susceptible to electromagnetic pulses from the sun. Zinkova writes that the storm would have only had to shift the ship's compass by 0.5 degrees to guide it off a safe course and toward the iceberg. Radio signals that night may have also been affected by solar activity. The ship La Provence never received the Titanic's distress call, despite its proximity. The nearby SS Mount Temple picked it up, but their response to the Titanic went unheard. Amateur radio enthusiasts were initially blamed for jamming the airwaves used by professional ships that night, but the study posits that electromagnetic waves may have played a larger role in the interference.

If a solar storm did hinder the ship's equipment that night, it was only one condition that led to the Titanic's sinking. A cocktail of factors—including the state of the sea, the design of the ship, and the warnings that were ignored—ultimately sealed the vessel's fate.
