Mt Fuji

Posted in Japan/Philippines on April 12, 2011 by nallurihp

Mount Fuji is known worldwide as one of Japan’s symbols. It is named for the Buddhist fire goddess Fuchi, and though it may not hold too great of meaning to outsiders, the Japanese consider it the holiest of their three scared mountains and place great importance in it.

Despite it’s beauty and serene appearance, Fuji is indeed a “perfectly” shaped stratovolcano. Fuji last erupted in 1707. This eruption began on December 16th and lasted into the next year until January 1st. Although there was no lava flow, the volcano erupted an immense amount of ash, the estimated amount to be around 800,000,000 m³. Fields and crops were ruined and the falling volcanic ash contaminated freshwater streams. As a result of this many parts of Japan suffered from famine and slowly starved. The ash in the rivers slowly settled to the bottom, and caused many of them to become shallower. The Sakawa river flooded because volcanic ash flew and made temporary dams here and there and eventually the downpour of rain the year following the eruption caused an avalanche of volcanic ash and mud and broke the dams, causing the flooding.

As of now Mt Fuji is till considered to be an active volcano, but the chance of an eruption any time soon has been deemed to be low.

Mt Fuji has been inspiring art for centuries, and above is a well known print of it by the japanese artist Hokusai.

Earthquake in Japan!

Posted in Japan/Philippines on March 29, 2011 by nallurihp

As we all know, there’s been a great deal of activity in Japan. Many of us have been following the news, and unless you’ve been living under a rock, you know that there’s been a massive earthquake in Japan. The earthquake warranted a 9.0 on the Richter scale, the second biggest earthquake recorded. This earthquake had some devastating consequences for the people of Japan. The estimated damages alone could cost up to 309 billion US dollars. The earthquake was so strong that it moved Japan nearly 8 feet closer to the States, and it caused a tsunami that caused even more damage. As of now there are 11,004 deaths, 2,778 injured, and 17,339 missing. To add insult to injury the earthquake caused explosions at multiple nuclear power plants, and the radiation contaminated much of their food supply.

However the people of Japan can’t relax just yet, the worst is not yet over. It is possible that the earthquake could trigger some of the many active volcanoes that are in Japan. Kirishima has already had a small eruption.

Here are some images of destruction the earthquake has caused:

The Philippines

Posted in Japan/Philippines on March 8, 2011 by nallurihp

With midterms week looming over us and the doom and gloom of Ohio weather, I think I can safely say that the majority of students here at Denison all wish we were in a place that’s a little warmer, a little sunnier, and a little less depressing overall. You don’t know how many times I’ve caught myself and others staring out of the window when actually we’re supposed to be paying attention the laws of logarithms that are up on the whiteboard. The Philippines are a nice enough place this time of year, right? Since there hasn’t been any recent volcanic activity in the area of Japan and the Philippines, why don’t we focus on the volcanic history of one of these exotic locales and escape the dreariness of Ohio for a bit? I’ve done a bit of internet surfing and here is more or less of a brief summary of what I’ve stumbled upon.

The Philippines are an archipelago of thousands of islands. For most of us who are fairly new the volcanic world, archipelagos are a chain of islands that are formed by tectonic movement and are more often than not, volcanic. One of the most active volcanoes in the Philippines (there are 37 volcanoes in all) is Mount Mayon. It is one the 18 active volcanoes in the Philippines and has erupted a total of 43 times and killed over 1300 since 1616. Mount Mayon is your classic sratovolcano, which just means that it is tall and cone shaped, built up from many layers of hardened lava and volcanic ash along with other debris. Other notable volcanoes in the Philippines include; Taal (which has had 33 eruptions since 1572), Butusan, and Canlaon. Below I’ve attached pictures of various Filipino volcanoes.

Above is a picture of Mount Mayon. You would would’ve never have thought something so pretty could cause so much destruction, huh?


And this is the Taal volcano, which is apparently quite a popular tourist destination.

Volcanic Activity in Japan and the Philippines

Posted in Japan/Philippines on February 27, 2011 by nallurihp

Volcano activity has been pretty quiet on the Pilipino front, not too much popping up news wise there. However ever since the end of January, Japan has had a bit of volcanic activity. Kirishima, which is considered to be one of Japan’s most active volcanoes, erupted on the 26th of January, and has had continued activity since. The eruption of Kirishima has caused the closing of many local train lines. The eruption of Kirishima has also produced lava fountains, lava flows and ash. The ash eruption itself reached a height of 25,000 feet. That’s almost five miles into the air, imagine that! And ever since then about 80 million tons of ash has fallen on the area around it since. There have also been explosions at Shinmoedake Volcano/Crater, nine to be exact. And apparently there is a large lava dome forming in the center which could lead to a pyroclastic flow, which as its ominous sounding name indicates, is very, very, bad.
