They just went with the closest volcano source in historic time, but it's abundantly clear from satellite the source is closer to Nabro than Dubbi.

shaggy Posted June 13, 2011 Share Posted June 13, 2011 Is this the main show or could these be smaller eruptions leading up to a larger one? Since these are such remote volcanos how much do they know about them and do they have monitering(i.e do they know how much pressure is being released) capabilities at these volcanos?

Zippy on the monitoring. Other than famous/unusual ones that erupt all the time like Erta Ale, they're barely even visited by Western geologists. Eritrea is even worse than Ethiopia in terms of access difficulty. Link to comment Share on other sites More sharing options...

Their charts are only showing the plume to 45kft. I've not seen any better estimates. From what I can tell from soundings, the tropopause is at 55kft.

PottercountyWXobserver Posted June 13, 2011 Share Posted June 13, 2011 So clearly it's a VEI4 then based off the equation. Now the question is, Is the SO2 reaching the stratosphere and according to VAAC it's not. Link to comment Share on other sites More sharing options...

Now the question is, Is the SO2 reaching the stratosphere and according to VAAC it's not. Well based on the error bars, there's a chance it's still just a VEI 3 so far. In any event, it's not Pinatubo - yet. Link to comment Share on other sites More sharing options...

Reports indicated that the eruption that took place in 4 different areas around Afambo, Nebro and Sireru causing a 5.7 rector scale earth tremor. The ensuing dust is covering hundreds of kilometers in the area, and that the quake has been heard in the greater portion of the region as a whole, according to reports. The Southern regional Administration disclosed that the Government has moved the inhabitants in the area to a safe place, in addition to providing them with the necessary care. No damage has so far been inflicted to human life , the Administration added. Although similar earthquake incidents were witnessed from time to time in previous years, yesterday’s tremor was of higher scale that led to volcanic eruption.
