Satellite NASA looked at the African erupting volcano (PHOTOS)

American satellite "looked" at the mouth of the volcano Nabro in Eritrea, which began erupting on the night of June 13 and introduced confusion in the African airports. Owned by NASA Earth Observatory website has published two picture, received on the 24th. The brighter of them — in pseudo: it shows the most hot surface.

These pictures are among the first detailed pictures of the erupting ash and lava flows. As noted on the site, satellite surveillance — is currently the only available way to monitor the situation. Nabro is located in an isolated area on the border with Ethiopia, Eritrea, and from the moment of his awakening was a little bit about the process of eruption.

In the picture in natural color is clearly seen as a dark bursts from the crater of a column of ash. To the north of the crater visible short inactive flows of lava. The lower part of the picture is a thick swirling smoke, blue on the edges — a sign that it includes a lot of sulfur dioxide. Finally, the black lava flows are visible to the west and south of Nabro.

The second picture, made in pseudo indicates that the active, hot lava flows are located to the west, the same as those to the south, are already chilled lava. The highest temperature — just above the caldera (depression, formed as a result of the failure of the top of the volcano). Molten lava ash painted in bright red.

Dense cloud of blue and white — it's mostly water evaporates, the lighter blue haze over the lava — it is the result of degassing.

Nabro eruption began with the release of the ash to a height of 13 kilometers. According to the U.S. Geological Survey, it was preceded by a series of aftershocks, maximum power was 5.7 on the Richter scale. The source first reported about another volcano Eritrea — Dubbo, allegedly awoke after 150 years. Unlike Dubbo, Nabro is active volcano.

In the first days of the eruption ash cloud posed a threat to the collapse of another aircraft — as it did in the past year due to the eruption of the Icelandic Eyjafjallajokull.
In particular, the tour was disrupted U.S. Secretary of State Hillary Clinton in Africa and in neighboring Eritrea, Egypt, even of emergency was declared. Currently, ash emissions, apparently, do not affect the continent's airports.

Satellite, make pictures, — Earth Observing-1 (EO-1) — was launched by NASA in 2000 as a pilot, designed to study the Earth. It is based on new technology and is part of the new millennium, the U.S. space agency. The satellite is equipped with, in particular, the device Advanced Land Imager (ALI), the capability to take multispectral survey of the land.
