Thanks to plenty of salt minerals and heavy elements in the soil, the Dallol volcano in Ethiopia produces brilliantly colored pools of water at the top of its caldera. And, as if to add greater effect to the already stunning sights, the volcano stands apart from the salt plains around it like an island. This hotspot was created through phreatomagmatic eruptions caused by magma interacting with water, and was further altered due to the presence of salt water.

Agueda in Portugal is the setting for this wonderful installation by Sextafeira called Floating Umbrellas. This colorful creation is a part of the Agitagueda art festival. Due to the fact that the same idea was used last year this is the second time the streets of this town have been covered with loads of vivid umbrellas, providing shade, as well as a wonderful sight. The people loved it so much that the repetitive nature of the installation does not carry the risk of becoming boring, but rather turning into a wonderful tradition.

The northeastern United States sweltered this week in a scorching summer heat wave, complete with stagnant, sticky air and no winds for relief, forecasters said. Even in a summer already filled with stretches of very hot weather, this week will be stubbornly brutal, with no relief in sight until the weekend brings thunderstorms to the region, they said. "Plain and simple, this week may feel the worst of any week for this summer in the Northeast," said Accuweather.com meteorologist Alex Sosnowski. (Reuters)

It has taken 3,000 hours and 34 years to make – but the results are incredible. Artist Scott Weaver has created a huge but incredibly detailed model of San Francisco using 100,000 toothpicks. The work entitled Rolling Through the Bay also doubles as a marble run. Ping pong balls dropped on several ramps at the top of the model follow several “tours” through the city. They pass matchstick replicas of sights such as Alcatraz, Fisherman's Wharf, the Golden Gate Bridge and the city's trademark terraced houses on steep hills.
