The Nubian and Somali plates are pulling apart about 5mm/year

If not, I will summarize.
The Fentale volcan last erupted in 1820. It has not erupted this time but it's magma is pushing the crust upward to make the way out to the surface. In so doing, it creates cracks, fissure or land deformations. In some place, it pushed the crust up by about 30cm.
The upward movement of the magma caused the east Africa tectonic plates, the Nubian and Somali plate, to pull apart from each other where land deformations or cracks happen. The plates are pulling apart by 5-6mm per year.

The uppward moving magma where it counters underground water, it boils it to hot steam which gushes out of fissures in the ground.

As the magma upward movement cintinues, pull against one another of the Nubian and Somali plates will widen the gaps between each, magma will come close enough to the surface to erupt as a volcano.

The Nubian and Somali plates pulling each other apart say at the max rate of 6mm/year.

In how many years will there be a 6km gap between them that will be filled with the waters of the Red Sea and Indian Ocean?

Solution:

Unit conversions
1m=1000mm
1km=1000m= 1000x1000mm= 1,000 000mm
6km=6,000, 000mm

Given:
The plates pull apart @6mm/year
No.years=6,000,000mm/6mm=1,000,000

In 1,000 000 years, the gap between the Nubian and Somali plates will be 6km, filled with waters of the Red Sea and Indian Ocean.

Addis Abeba will be within 100km west of what may be called the Great Rift Sea. Welkite will 225km west of the Great Rift Sea.

Dama,

Thank you for your intuitive post. There is visual evidence that the area around the old railway station of Metahara with vast area of charred surface. If you had the opportunity to travel by train on the former Chemin de Fer you could have seen it. You could also get a smell of sulphur when your train approaches Bordode(Harba) from Gara Gumbi in the distant west bordering Arsi.

I remember from my childhood years a deep surface crack that runs between the vicinity of Asabot where I was born and the next railway station Mieso. I scoured Google map looking for it after reading your post and there it was. You can see it. That deep crack was obviously created by a violent earthquake that shook up the area in the past. I also remember a mild tremor that was felt around Gara Asabot when I was a kid and how everyone ran outside. It was fun and exciting for us kids but it was not funny for our parents and every adult in the area. The effects of earthquakes is in the folklore of the inhabitants and such tremors terrifies them to the core. It has been quiet for so long it may be overdue for a big one and I doubt that it is in the minds of city planners of that country. Let’s hope and pray that it will never happen. That includes countries of Eritrea, Ethiopia, Djibouti and Somalia.

Thank you again for educating everyone in such elementary terms.

I didn't finish watching the video, I think there are sorts of repetitions over and over from the lady, without providing more concrete and empirical data to the claims.

Somebody may think can play the role of Early Warning System, in the absence of a real one in a poor African country.

The last time I check Ethiopia has got a ministry or department of Geophysical Observatory and Geological Science or something similar.

She is trying to present some technical and highly scientific topic in a Youtube channel, without adhering to the principles of scientific methodology. Why?

Did she try to contact the relevant authorities in the country with her own findings and offered to share with them? This is not a simple matter, she said repeatedly, as it affects potentially the lives of hundreds of thousands, if not more. She presented as a case of emergency and couldn't find anyone to turn to other than the Youtube channel to warn the affected people, it seemed to me.

I could be wrong but thought plate tectonics causes magma uprisings or earth quakes, not the other way round like you put it here. Not only your level of political bickering but also your understanding of scientific concept is as well just as half cooked as the former.

It is all good to share any information with the relevant authorities and the wider public but also it is critical to not over state and terrorize the public and endanger their safety while doing so.

Dummy! Forget geology! You're not created for it cadre. I mean, no brains except mucus.
And cruel! Angry at a foreigner who did her part for humanity. Tell your bosses to do their part. Tell them to evacuate residents with 15km on each sides of the cracks. Both videos recommend this. The magma is very near the surface. Sooner than later will erupt, may be about 6km down.

Okay, dude.
Me dummy, no problem, I didn't claim to be a guru in the subject matter here. But I have exposed the flaws in your assumptions on the subject matter, did you refute that? If not, then why not?

Evacuate people from their homes based on youtube channel information? Where are you from, in the first place?

How did you come to the conclusion that the 15KM distance from the "crack" is safe? Which crack anyway? I think to have heard that there are multiple cracks, not only a single crack, isn't it?

In Geological Timescale 100s, 1000s or even 100,000s of years are considered soon, how soon is that expected eruption? Based on which kind of measurement that you detected that magma is just 6Km beneath the surface?

I am not created for it, I didn't imply that as well.

If you fail to answer the concrete questions here in this regard, then you are in fact a supper dummy!

The same way I responded to you recently by doubling the qualification you attached to me, did you forget?

A quadruple liar!

[Dama]

Good God!
Why dont you just shut the fck up? You dont know where the cracks are? Where waters gush out? How close the magma is to the surface? Why about 15km from the cracks to evacuate?
Look. Stop being an idiot.
