It’s Volcano Week 4 here at GSS. Volcanoes, about a week. You know the drill!

Rising up from the pastoral plains of Luzon Island in the Philippines is Mount Mayon, an active 2,400 metre-high stratovolcano. Known as the “perfect cone,” Mayon Volcano looks surreal in its symmetry, a true masterpiece of nature.

The volcano rises up in stark contrast to the surrounding flat terrain, its upper slopes averaging a 35-40 degree grade. Eruptions occur primarily from a small volcanic crater but have also created pyroclastic flows that carved over 40 ravines around Mayon’s cone. Viewing Mt. Mayon in Google Earth shows its unique shape:

With 47 eruptions since 1616, it is the most active volcano in the Philippines and remains a danger to nearby villages even today. Its deadliest eruption took place in February of 1814 and killed over 1,300 people. During that Pompeii-style eruption, Mayon Volcano reportedly spewed plumes of hot ash while fast-moving lava flows completely covered the village of Cagsawa. The town’s bell tower was the only structure left standing after the eruption had ended.

In recent decades, Mayon Volcano has continued to make its presence known in the region. With eruptions in 1984, 1993, 2006, and 2008, the residents of nearby towns and villages have become accustomed to frequent evacuation warnings and safety alerts. If you’re one of those adventurous¹ types who likes a steep uphill climb, try Mount Mayon, but be sure to wear a helmet and watch for falling debris and hot magma.

Beauty sometimes erupts from utter disaster. Take, for example, the gorgeous crater lake that formed in the remnant bowl of the 1991 Mount Pinatubo eruption in the Philippines. A stunning natural wonder was created from one of the largest, most devastating volcanic eruptions in the past 100 years.

No one knew there was volcanic action happening far below the surface of Pinatubo. The local indigenous people, the Aeta, had no recollection of any previous blasts in their oral history and geologist data was scarce as well.

Yet, during the month of June, 1991 the mountain spewed forth 10 cubic kilometres of hot, molten magma; injecting more aerosols into the stratosphere than that of Krakatoa – one hundred years before.

Due in part to Typhoon Yunya that was ripping through the island nation, the ash cloud that should have been spread over the surrounding oceans instead cycloned back over the Luzon region, where Pinatubo once lay dormant.

The mixture of the typhoon force winds and rain with the ash cloud resulted in a rainfall of heavy mud causing considerable damage to neighboring cities. This included the already evacuated Clark Airbase, a U.S. Air Force establishment, whose many flat-roofed buildings collapsed under the weight of the ash and mud.

The military never permanently returned to the base, instead they turned it over to the Philippine government, who converted half of it into a Philippine Air Force base and the other half into a Holiday Inn Resort complex.

It is easy to see the ravines and canyons coming down the sides of the mountain that are now filled with lahar, a volcanic mud mixture. Lahar filled river beds streak the landscape leading away from Pinatubo.

After years of rainfall, the basin of the once-mountain filled with water to form Pinatubo Crater Lake. Now a tourist destination, many will trek for several hours through deep jungle trails to reach the clear waters of the lake.

Back in 2002, the lake had filled the crater so much that there was fear that the rim might collapse, causing considerable damage to local farms and endangering some 45,000 residents in neighboring villages.

To prevent such a collapse, the government commissioned engineers who sand bagged a makeshift river bed, using a lahar mudflow path, 5 metres wide and then cut a notch the same width in the lowest part of the crater’s rim. They managed to drain off 25% of the crater’s water into the nearby Bucao River.

All in all the blast at Pinatubo caused the displacement of hundreds of thousands of people, the deaths of over eight hundred, and damaged billions of pesos worth of property, buildings, and farmland. But, they got a very beautiful lake out of it – that is, if you’re willing to make the trek.

The world of gargantuan statuary has changed considerably since we published the original Very Large Buddhas post just over 3 years ago. The title of world’s largest statue is now held by the Spring Temple Buddha in Henan, China.

The statue alone is 128m tall, and it stands on a 20m tall lotus throne, which in turn stands on a 25m tall pedestal – giving the structure a total height of 153m.

The statue – including the lotus throne – is 128m tall. Its original 25m tall pedestal gave the structure a total height of 153m. However, recent information shows that the hill it was built on has been constructed into an additional pedestal. The total height is now believed to be 208m. Panoramio has several pictures, and this image in particular gives you a sense of just how immense this monument is (and shows the new pedestal under construction.)

Little is known about the Spring Temple Buddha in the West, so it likely wasn’t listed on Wikipedia when Alex wrote the original post. It was constructed in 2002 in response to Taliban bombing of Buddha statues in Afghanistan, as well as to thwart Indian plans to create the world’s largest statue.  I haven’t been able to find any vital statistics about it, but this image seems to show that the toes alone are close to 2m high.

The world’s second largest statue is the Laykyun Setkyar in Myanmar, which is so new (completed in 2008) that we only see it partially constructed on Google Maps.

At 116m on a 13.5m pedestal it is barely taller in total than the Spring Temple statue alone. Panoramio has a few pictures of the completed structure, which also show that it is, interestingly, located near a reclining Buddha which, at 90m in length, would probably be the world’s 9th tallest statue if it was upright.

As it is also located in a somewhat secretive country, detailed statistics are similarly hard to find. The regime consistently claims it is the world’s largest though, despite evidence to the contrary.

The world’s third largest statue is Ushiku Daibutsu in Japan. It was featured in the original Very Large Buddhas post, though there is new imagery that shows it in greater detail.

Thanks to Lukasz for the link to the reclining Buddha, and to Alex for letting me update his original post.

The Darvaza (Darweze) natural gas crater is an endlessly smouldering geological anomaly located in the isolated Karakum Desert of Turkmenistan. Known locally as the “Door to Hell,” this close relative of the “Pool of Fire” and little-known tourist attraction has been on fire for at least three decades.

Above, we see the natural gas crater (barely) as a glowing red spot in an otherwise unremarkable landscape. Given the low quality of the satellite imagery in this area, it is surprising that anyone knows that the “Door to Hell” even exists. This begs the rather existential question: if a crater is burning in the middle of nowhere, does anyone see it?

As a matter of fact, a group of Russian geologists experienced it first hand in 1971¹ when the ground beneath their drilling equipment collapsed creating the abyss. Dispatched to the Karakum desert by the Soviet Union, they were searching for natural gas and found so much of the stuff that harvesting it became unsafe. With noxious gases threatening to harm nearby villages, the geologists set the seeping crater ablaze, unwittingly lighting the largest barbecue known to man.

The “Door to Hell” crater has been on fire ever since and shows no sign of stopping. Visible from a great distance, the glow from this eternal flame can even be seen in Google Earth’s City Lights layer.

Wow, that’s bright! Visitors to Turkmenistan can venture out to see hell first hand, but there aren’t any organised tours so you have to hire your own driver². Now who’s up for toasting the World’s Largest S’more?

Some really awesome photos of both craters can be found on this photography site and an impressive video of the “Door to Hell” is available on YouTube.

Despite Indonesia having more Muslims than any other nation in the world, making up 87% of its total population, the government’s pseudo-religious tolerance¹ is seen within several religious buildings, all standing within a few city blocks of Indonesia’s central seat of power and the highest court in the land.

With over 200 million Muslims in a country whose “religious freedom” is mere decades old it is not difficult to see the significance of these Muslim, Hindu, and Christian influenced buildings.

What you don’t expect to see in the heart of Indonesia is a 100 year old Catholic cathedral. Yet, there it is.

The Central Catholic Cathedral (Gereja Katedral) is the seat of the Archbishop of Jakarta. The current building is a rebuild of the original that was burnt down in the mid-1800s. On Christmas Eve, 2004, the church was the target of a blast bomb attack.

What you do expect to see in a highly populated Muslim country is a mosque. Just a 150 meters from the great doors of the Cathedral are the great halls of the largest mosque in Southeast Asia.

What is significant about The Independence Mosque (Istiqlal Mosque), besides its size, is that its designer was not a Muslim at all. In fact, he was a Christian architect that won the job as part of a contest held by the government in the 1960s. The mosque would take 17 years to build.

Just one block away from The Independence, the same Christian architect, Frederich Silaban, designed another one of Jakarta’s treasured monuments, the National Monument (Monumen Nasional or MONAS); this time taking his influences primarily from the Hindu religion.

Taking 14 years to build, the National Monment is a 137m tall tower that supposedly symbolises the fight for Indonesia’s independence. Visitors generally stand for hours in long lines while they wait to ride up the old, rickety 11-passenger elevator up the deliberately phallic-looking shaft to the central viewing platform. The design of the monument supposedly “combines elements of the male and female physiology”, symbolising fertility in the Hindu-Javanese tradition.

All three of these religiously influenced buildings demonstrate, to a certain extent, Indonesia’s religious tolerance. For if we just cross the street from the National Monument, we will come upon the Presidential Palace (Istana Merdeka) and the Supreme Court of Justice (Mahkama Agung); arguably the nation’s most important political buildings.

The Presidential Palace / The Supreme Court of Justice

From the viewing platform of the National Monument tourists can photograph all of the buildings discussed here within a single panoramic frame. The President’s home, the Supreme Court, the largest mosque in SE Asia, and the central Catholic cathedral all from an Hindu-influenced monument. An impressive vista for sure.
