  • Tunguska event epicentre – Russia, Krasnoyarsk Krai. The site where an enormous explosion took place in June 30 1908. It is considered that this blast was caused by large meteoroid and is the largest impact in land in the newest history of Earth. Similar event in metropolitan area would lead to death of millions of people.
  • Wabar craters (al-Hadida meteors) – Saudi Arabia, Eastern Province. Unusual impact craters in the desert of Arabia. Legendary site, where iron meteorites of large size have been found. Well preserved craters show that the impact was very recent, most likely – the early 18th century.

  • Henbury meteorite craters – Australia, Northern Territory. A group of 13 – 14 meteorite craters with a diameter from 7 to 180 m, up to 15 m deep. Here have been found several tonnes of meteorites. Formed some 4,200 years ago.
  • Mahuika Crater – New Zealand, near Snares Islands. Potential impact crater on the bottom of sea, 20 km wide and more than 153 m deep. It is possible, that the meteorite fell sometimes around 1443 AD, creating incredible tsunami waves up to 220 m high.

  • Nördlinger Ries – Germany, Bavaria. Enormous impact crater – a large circular depression with a diameter of 24 km. Formed 14.3 – 14.5 million years ago (Miocene). Currently the crater is 100 – 150 m deep, at some places there are exposed the rims.

North America

  • Meteor crater (Barringer crater) – United States, Arizona. Visually the most impressive meteorite impact crater on Earth. The diameter of the crater is about 1,180 m, depth – 170 m. The outer side of the rim rises 45 m high above the surrounding plains. The bottom is covered with 210 – 240 m thick layer of rubble. Impact took place some 49,000 years ago.

  • Chicxulub crater – Mexico, Yucatán. Ancient impact crater, with a diameter more than 180 km. One of the largest impact craters on Earth. It was shaped 65 million years ago and it is considered that this fall of bolide led to the great extinction of dinosaurs and many other animals and plants.
  • Haughton impact crater – Canada, Nunavut. This impact crater is located in a very remote area on Devon Island. Diameter – 23 km, formed some 39 million years ago (Eocene). Permafrost has helped to preserve this impact crater very well and the site is considered to have a very similar environment to Mars.
  • Manicouagan Reservoir – Canada, Quebec. Enormous, ring-shaped reservoir, formed in the impact crater. The impact took place 214 million years ago, shaping approximately 100 km wide crater. The central part of the lake is taken by the enormous René-Levasseur Island, with 2,020 km² area.

  • Carancas impact site – Peru, Puno. Site, where in September 2007 fell a meteorite. It created 4.5 m deep and 13.5 m wide crater. Some local people later became ill, the nature of this illness is not explained.

General description

Category includes outstanding impact craters – detectable scars on the surface of Earth left by a body coming from outer space. Category includes also meteorites – natural objects from the outer space.

Bombardment from the space

There are many pieces of solid matter flying around in the space. And VERY frequently they fall on the surface of Earth. There are estimates that every year on Earth fall 18,000 – 84,000 meteorites larger than 10 grams: e.g. one meteorite every 6 – 30 minutes. Every 500 years meteorites form a crater with a diameter of 100 m. It is rather unusual that no giant meteorite has devastated Earth over the last two million years – but it is also calculated that just a few percent or all small craters is found thus far.

The speed of meteorites is dizzying: up to 15 – 20 kilometres per second! Theoretically they might be even 70 km/s fast (252 000 km/h…). Now try to imagine what happens if meteorite has a diameter of one kilometre and hits the surface of Earth 300 times faster than jet aircraft! It burns a profound hole in atmosphere and kicks the crust of Earth with a terrible force.

Earth has experienced such terrible bombardment. It has been calculated that meteorites with a diameter of 1 km hit Earth every 500,000 years and sometimes there come true behemoths, with a diameter more than 10 km. They leave scars in the surface of Earth and traces in the history of climate and life.

The scars – impact craters

As the meteorite hits the ground, it is suddenly stopped by the solid mass of Earth’s crust. Energy can not disappear without a trace – and the immense kinetic energy of the meteorite is transformed into thermal energy: an incredible explosion takes place in the impact site. If the meteorite is smaller, it may explode before hitting the Earth surface, but if it is large – it penetrates the ground and explodes under it, creating a circular crater.

The size of such craters on Earth might be amazing. Vredefort Crater in contemporary South Africa was created by 5 – 10 km large asteroid some 2 billion years ago and has a diameter of 160 km. It seems that this blow triggered the creation of new volcanoes around the impact crater. Nowadays it would erase most life forms on Earth.

The giant impact craters have left much more profound changes and can be detected even billions of years later. Such catastrophic events happen very rarely – once in ten or a hundred million years. As a result these craters still exist but have lost their "visual appeal" – they are just circular structures in the Earth’s crust, very often covered with later sediments.

Smaller impact craters disappear much sooner (if a few million years go together with a term "sooner") but they are more frequent. If they are recent, they still look like true craters and have a visual appeal.

How many impact craters are on Earth?

The existence of impact craters on Earth has been proved recently – in the 1920s. Since then there have been found some 190 impact craters around the world. They are diverse. Some are small, distinctive and fairly new craters. Some are very old, large and eroded. And – some are covered with sediments and invisible.

Theoretically the density of impact craters on Earth should be uniform – there is no reason to believe that some parts of Earth are hit more often than others. The density of known craters though isn’t uniform. There are known more craters in:

  • Places where the geological exploration has been more intense – United States, Europe, South Africa etc.;
  • places, where are exposed old rocks – Canada, Scandinavia, Sahara, Australia.

Very few impact craters are known in oceans – the ocean floor is constantly renewed by geological processes and can not preserve impact craters which are hundreds of millions of years old.

It is expected that many more impact craters will be discovered in the future, but most of them will not be visually impressive structures – they are buried under thick layers of sediments. But there still are discovered visually very interesting impact craters as well – such as the Kamil Crater (Egypt), which was discovered through Google Earth application in 2008.

And, don’t forget, new craters will be formed as well. Every minute there can fall a large meteorite which can cause a devastating explosion and leave a fresh crater.

Impact Craters of Earth

Craters have been found on planets and moons throughout the solar system, caused when asteroids or meteors have collided with them. Our Earth has not escaped these impacts, and nearly 200 craters are known on Earth today. Some are easily visited, others are in locations few would ever want to get near. This book details all the known terrestrial impact craters, telling their age, size, and other details, as well as highlighting those easily visited.

Sites of Impact

The best-preserved impact sites are often difficult to access – buried under ice, obscured by foliage, or baking in desert climes. These desolate landscapes are connected to another place outside of our world, and for photographer Stan Gaz they are sites of pilgrimage – steps in a journey begun as a curious young boy accompanying his father on geological expeditions, and culminating in a six-year journey traveling the globe in search of these sites, much of that time spent leaning his medium format camera out of an open-sided helicopter.
