Submarine volcanoes are underwater fissures in the Earth's surface from which magma can erupt. They are estimated to account for 75% of annual magma output. The vast majority are located near areas of tectonic plate movement, known as ocean ridges. Although most are located in the depths of seas and oceans, some also exist in shallow water, which can spew material into the air during an eruption. Hydrothermal vents, sites of abundant biological activity, are commonly found near submarine volcanoes.

Havasu Falls

August 26th 2011 02:52

The Havsuw’ Baaja (Blue Water People), or more commonly the Havasupai, are an American Indian tribe that has called the Grand Canyon its home for at least the past 800 years.

The Havasu Falls which bears their name is the second waterfall in the canyon. It is located 1 ½ miles from Supai and is accessed from a trail on the right side (left side when heading upstream) of the main trail. The side trail leads across a small plateau and drops into the main pool. Havasu is arguably the most famous and most visited of all the falls, and is considered one of the most photographed waterfalls in the world. The falls consist of one main chute that drops over a 120-foot (37 m) vertical cliff (due to the high mineral content of the water, the falls are ever-changing and sometimes break into two separate chutes of water) into a large pool.

The falls are known for their natural pools, created by mineralization, although most of these pools were damaged and/or destroyed in the early 1990s by large floods that washed through the area. A small man-made dam was constructed to help restore the pools and to preserve what is left. There are many picnic tables on the opposite side of the creek and it is very easy to cross over by following the edges of the pools. It is possible to swim behind the falls and enter a small rock shelter behind it.

It is interesting to note that the falls were called "Bridal Veil Falls" before the flood of 1910 because they fell from the entire width of the now dry travertine cliffs north and south of the present falls.

Snake River and the Teton Ranges

July 15th 2011 02:42

The Teton Range is a mountain range of the Rocky Mountains in North America. A north-south range, it is on the Wyoming side of the state's border with Idaho, just south of Yellowstone National Park. Most of the range is in Grand Teton National Park.

The Snake is a major river of the greater Pacific Northwest in the United States. At 1,078 miles (1,735 km) long, it is the largest tributary of the Columbia River, the largest North American river that empties into the Pacific Ocean. Rising in western Wyoming, the river flows through the Snake River Plain then rugged Hells Canyon and the rolling Palouse Hills to reach its mouth at the Tri-Cities of the state of Washington.

The famous image below of Teton Range, from the Snake River overlook, was taken by American photographer and environmentalist Ansel Adams in 1942.

Are Earthquakes Becoming More Frequent?

June 17th 2011 03:16

Earthquakes: Are There Really More Now Than Ever Before, or Are We More Aware of Them?

In recent times there seems to have been a large number of natural disasters affecting our planet. Are there really more earthquakes occurring now than in the past, or in our modern age of instant information and news on demand does it only seem that way?

click to enlarge

As this graph demonstrates, every year there are a large number of serious earthquakes, some years have more than average and some less. In 2010 & 2011 there has been more than average, but 2005, 2006 and 2008 for example had less than average.
In terms of media coverage, even before the internet age natural disasters which led to large losses of life would receive massive media attention. Therefore the location of an makes a huge difference. The majority of quakes have epicenters in the middle of the ocean where the effect on human life is very small. It's when quakes occur near populated cities that the human tragedy and media coverage steps in.

The graph below shows the lives lost due to earthquakes each year. As this clearly demonstrates, it's not the total number of earthquakes in a given year that matter, but where they hit.

Anatomy of an Earthquake

May 13th 2011 23:44

As the infographic below explains. The surface of the earth is divided into seven major plates and several minor ones. They move a few centimetres each year riding on semi-molten layers of rock underneath the crust. As the plates move they pull apart of collide unleashing powerful movements known as earthquakes.
The effect of powerful earthquakes can be ground and building rupture, landslides, tsunamis and much more.

Nyiragongo Crater

April 25th 2011 02:30

Mount Nyiragongo is a stratovolcano in the Virunga Mountains associated with the Great Rift Valley. It is located inside Virunga National Park, in the Democratic Republic of the Congo just west of the border with Rwanda.
The main crater is about two km wide and usually contains a lava lake. Nyiragongo's lava lake has at times been the most voluminous known lava lake in recent history. The depth of the lava lake varies considerably. A maximum elevation of the lava lake was recorded at about 3250 m (10,700 ft) prior to the January 1977 eruption - a lake depth of about 600 m (2000 ft).
Nyiragongo and nearby Nyamuragira are together responsible for 40% of Africa's historical volcanic eruptions
