August 7 - Kon Tiki Smash!

Posted on August 7, 2020

These giant headed statues - and the unusual name of the islands where they're found - are they familiar to you? 

Statues on Easter Island 






 Would it surprise you to know that Easter Island is located in the South Pacific?



Would it surprise you to know that it is a special territory of Chile?


Easter Island's first inhabitants settled the island around 1200 A.D. - the time when Europe was still in the middle of "medieval times" and Genghis Khan was busy setting up the Mongol Empire. A Norwegian explorer and writer named Thor Heyerdahl believed that these first inhabitants, the Rapa Nui, came from Peru. But this idea goes against the oral history of the Rapa Nui. Also, studies of culture and language tie the Rapa Nui to other Eastern Polynesian peoples such as Hawaiians and Tahitians. 

Basically, Heyerdahl was almost surely wrong. (But, if you keep reading, you will find out that he is probably also partly right!)

Heyerdahl got it into his head that the big-headed statues - which are called moai - are more like pre-Columbian Peru art than like Polynesian art. In 1947, he set out to prove that sea travel between Peru and Easter Island was possible with the kinds of materials and seafaring knowledge that Peruvians had back in the 1200s.

Heyerdahl presided over the construction of a wooden raft. It was made from nine balsa tree trunks lashed together with hemp ropes. Pine splashboards were added to the bow so that the raft wouldn't sink in the waves, and mangrove wood was used to create A-frame masts. 


Heyerdahl named the raft Kon-Tiki. He outfitted the raft with drinking water in both modern cans as well as sealed bamboo rods, which would have been like water containers created by early Peruvians. He also carried coconuts, sweet potatoes, and other fruits and roots. Of course, he had packed some modern equipment - radios and cameras, for example - but those pieces of equipment were to keep the expedition safe and to record the journey. They were incidental to proving the claim that early Peruvians could have made the ocean crossing.



Along with five companions and a pet parrot, Heyerdahl sailed the raft for 101 days. On this date in 1947, the Kon-Tiki smashed into a reef surrounding an island in Eastern Polynesia (an island called Raroia, not Easter Island), and all six men safely disembarked.

I imagine that this was a later photo.
The Kon-Tiki crew did not look like THIS
after 101 days on the ocean!

They had crossed almost 7,000 km (around 4,300 miles) of open ocean.

Even though Heyerdahl's expedition didn't reach Easter Island itself, the raft journey was proof-of-concept that pre-Columbian Peruvians could have made the sea journey to the island. 

Since Heyerdahl's time, we now have the ability to trace genetic heritage through DNA evidence. And - although scholars say that the Rapa Nui were Polynesian - DNA evidence indicates that at least a few Peruvians did indeed make the sea crossing. There was a "genetic mixing event" near the beginning of humans living on Easter Island!

Even though the moai have disproportionally large heads,
they DO also have bodies. But in some shots, we see
moai that are buried up to their shoulders...and so we
often think of the Easter Island statues as being giant
heads!

October 8 - Battle of Angamos in Peru

Posted October 8, 2019

Today visitors to Peru might get to see a military parade honoring Admiral Miguel Grau Seminario, arguably Peru's greatest modern hero, who died on this date in 1879.


It's always surprising to me when a nation celebrates a military LOSS, rather than a victory, but this battle with Chile, during the War of the Pacific, didn't go Peru's way. As a matter of fact, this was the deciding battle - Peru started out stronger in the war but ended up losing. 

Grau was not only courageous, he was caring. When he was winning battles and - at that point - the war, he begged the Chilean captain who'd clearly lost to surrender and save what remained of his sailors. But the Chilean captain refused to surrender, and when Admiral Grau sunk his ship, the captain boarded Grau's ship but ended up dying in combat. Grau ordered his men to save all the Chilean sailors that they could and take them to land. 

Before the war, and before he had become an admiral, Grau had traveled to the United Kingdom on behalf of Peru to order and oversee the construction of ironclad ships that were lighter and more maneuverable than earlier ironclads. One of the ironclads became his own flagship, the Huáscar



Grau and the Huáscar had so dominated in the War of the Pacific, Chilean leaders decided that they had to work hard to either destroy or take command of that ship. So two Chilean ironclads AND three other Chilean ships all went after Grau in a surprise attack. Grau realized that he was badly outnumbered and tried to flee. He became trapped, however, and when Chilean ships opened fire, it was with armor-piercing rounds that hit Grau's command tower and killed him instantly. The Peruvian forces tried to fight on! - realized they had better scuttle the ship! - decided too late and were boarded by the Chileans! 

The death of Grau and the capture of the Huáscar were devastating blows that resulted in the eventual loss for Peru. Losing the war meant losing a chunk of resource-rich land to Chile, and it was even worse for Peru's ally, Bolivia, because it lost its only chunk of coastline to Chile and therefore became landlocked.

May 22 – Tectonic Blast! Tectonic Crack!

Posted on May 22, 2019

When we talk about Natural Disasters, we are often talking about terrible weather:

Brutal sandstorms, violent lightning strikes, killer tornadoes, deadly blizzards, destructive hurricanes (or typhoons or  cyclones; all three are basically the same thing).


But there are Natural Disasters that are not weather-related. Instead, they have to do with tectonic forces.

Tectonic forces are those that originate below the Earth's surface as a result of the movement of the continental and undersea plates. The two main disasters in the "tectonic" category are volcanoes and earthquakes.

The Earth's crust is made up of a lot of different
tectonic plates that move around!



Volcanoes

On this date in 1915, Mount Lassen erupted violently, ejecting rock and pumice, ash and gas. The ash and gas formed a column more than 30,000 feet tall - it could be seen from as far away as 150 miles! A large, deep crater formed at the mountain's summit. Only three square miles of nearby region were devastated, but mudflows and pyroclastic flows of hot ash, pumice, and rock reached many more miles.




Don't worry, Mount Lassen's eruption didn't kill people, although it did cause a few minor injuries among people escaping the mudflows. The thing about volcanoes is that they commonly are rocked by earthquakes before they erupt, and they often vent steam or show other signs of being active before they blow big. Lassen woke up on May 30, 1914, after 27,000 years of being dormant, and there were about 400 eruptions between 1914 and 1921, including the one we commemorate today (the biggest eruption of them all).

Because it was the first U.S. volcano to erupt in the 1900s, Lassen Peak's eruptions and activity were very well photographed and studied. 

Lassen Volcanic National Park is a lovely place to visit -
although of course scientists monitor tectonic activity
and earthquakes in case the volcano shows signs
of becoming active once again!
When two plates collide, volcanoes can
form above the collision zone.

Earthquakes

The most powerful earthquake ever recorded occurred in Chile on this date in 1960. It ranged from 9.4 to 9.6 on the "moment magnitude scale" (expressed in the terms we are pretty familiar with from the Richter Scale). 

Unfortunately, the "Great Chilean Earthquake"
and the tsunamis that resulted from the quakes
caused a lot of damage and many deaths.

Damage in Hawaii, more than 6,000 miles
(10,000 km) away from the earthquake's
origin.
The earthquake set off tsunamis that did more damage, even, than the original 10-minute-long shake. The tsunamis kicked off waves up to 82 feet tall; a tsunami devastated Hilo, Hawaii, several local tsunamis battered the Chilean coast, and high waves affected faraway spots like the Philippines and Japan!

Like the volcano, this powerful earthquake had some warning - but the warning was an earlier almost-as-powerful earthquake! On May 21, 1960, an 8.1 quake rocked Chile. On May 22, 1960, two more strong earthquakes hit in the same locale as the first; fifteen minutes after the third quake, the monster 9.4 quake hit around 280 miles (460 km) away from the first three.

Smaller aftershocks shook Chile until June 6.

Just as the collisions of tectonic plates
can cause volcanoes, these collisions
can also cause earthquakes.


Tectonic plates cause what has been
called "continental drift" - the slow
changing of the number and position 
of the continents.
