Volcanic eruption created changes in Ethiopia

A team of geologists and geophysicists dispatched to Northeast Ethiopia, where volcano has recently erupted, confirmed that the eruption caused surface displacement in the area.

The volcano has recently occurred in the area located at 65-kms northwest of Semera, capital of Afar regional state.

Geologists drawn from Institute of Geophysics, Space Sciences, Astronomy and Earth Science Department of the Addis Ababa University, Universites of Cambridge and Oxford told ENA over the weekend that the volcano, which occurred on June 29th , 2009, has created about 4.5-kms opening within a 60-km-long dyke created in the area in 2005.

According to the geologists, the 2-meter wide dyke has extended from Dabbahu to Harraro areas.

With the expectation of more volcanic events in the region, Dabbahu-Manda-Hararo is the most active area on the planet right now, they said.

Assistant Professor at the Institute of Geophysics, Space Sciences, and Astronomy of the Addis Ababa University, Dr. Elias Lewi said that number of volcano incidents happened in the area since 2005.

Most of the volcanic eruptions that occurred in the region remained beneath the surface of the earth, he said, adding, the recent one is the fourth eruption in Ethiopia since 2005.

According to him, the eruption was a follow-up to the dyke created due to similar eruption four years ago .

The recent volcano covering 4.5 square kilometers has also created small hills elevated from 30 to 40 meters.

Associate professor at the institute, Dr. Tesfaye Kidane on his part said lava has overflowed from the dyke that covers 5-kms long and surface displacement occurred following the eruption.

He said that bigger eruptions and earth quakes are expected to happen in the next five years.

The geologists urged responsible bodies in the region to consider the issue in any of development activities being undertaken in the area.
