They are known as Mount Olga Urulu and in Australia and its origin was a mystery.

If you want to envision the coordinates indicated what can be done from the website free Google Earth can see the earth as if on a satellite with a telescope.

Urulu. 25 ° 20.26 ‘13 “S 131 ° 02.22 ‘21″ E

Mount Olga. 25 ° 17.54 ‘68 “S 130 ° 44′45, 15″ E

Originally part of an asteroid equivalent to 3280 meters in diameter collided at 32 km from where the Urulu, with an average density of 2.5 ‘-.

The onset of impact is 25 ° 07′01, 89 “S 130 ° 50′18, 37″ E

The distance between Mount Olga and is 20 Km Urulu

The distance Urulu first area of impact is 32 Km

The distance from Mount Olga at the beginning of impact is 24 Km

The astrobleme I leave the impact that was tangentially with 22 ° tilt, created a teardrop shaped footprint of 20.1 km long by 24.2 km wide.

It was accompanied by three other smaller asteroids that hit with a larger angle in the coordinates where the center have created three craters 8 km 7 km and 7.6 km

Crater 1 of 8 Km 25 ° 05′11 “S 130 º 45.35 ‘18″ E

Crater 2 of 7 km 25 ° 03′02, 86 “S 130 ° 54′20, 87″ E

Crater 3 7.6 km 25 ° 06′11, 38 “S 130 ° 59 ‘52.48″ E

The entry speed was approximately one km per second, very low speed compared to meteorites, all because of the gravity of our planet to asteroid kidnapping.

There was little heat radiation due to the slow speed.
A una distancia de 100 Km. se produjo un terremoto de 7.1 en la escala de Richter.
There are other impacts within a radius of 300 km
