What do the spikes mean ?

[Freddie123]

So I wonder if that means more magma is flowing into the magma chamber than can get down the fissure and thus its pushing back up?

still up

Hi JP

 

with regards to the gps plot,does this entail that pressure is building there,i know that when then graph drops,the caldara is dropping,at least i think it is,still non the wiser in this game.

 

there is talk of a +5 mag recently,i suspect this is not confirmed yet.

 

big drop on gps now.

[Tom Jarvis]

big quake just happened as well m5+

[john pike]

hi allseasons

your correct

 

the drop is showing still

 

although slower

 

when you get an uplift that shows pressure has released on it briefly

possibly slightly less magma flow or possibly a gas release from somewhere

although so hard to call as you would need to see inside exactly what its doing

needs checking

but not too far from ketla 

[Polarlow]

Big one Guessing M5.8 !!!!

 

Could be the biggest Quake since eruption begun !!!

[Polarlow]

Fissure eruption has just died .......... Whats happening ........... WOW !!!!

[karyo]

All of a sudden the fissure eruption appears to have almost stopped in the Mila webcam. Either there are problems with the webcam or the fissure got blocked due to all the earthquakes!

 

Edit: it is starting again now so it was not a webcam problem.

If Say a m9 earthquake struck would it be felt here in the uk?

[summer fun]

USGS has it at 5.1 

 

1. 5.1108km WNW of Hofn, Iceland2014-09-16 22:34:15 UTC+01:005.0 km

 

could change though.

 

it also has a 3.1 in Alaska @m 194.3km deep. Thats a pretty deep earthquake.

[Polarlow]

THe blinking lights of the sensor are still visible

Caldera dropped 1.1meters in last half hour !

Eruption stopped again !!!!!!!! ???????????

[karyo]

Completely stopped now!!!

 

Where is all the pressure going?

[summer fun]

Looks like it just finished.

 

Maybe we will begin to see pressure rise again now there is nothing coming to the surface.

 

Or the quiet before the big eruption.

 

Who knows but this really keeps this interesting.

somewhere 5,6 to 6

 

cams like you say showing nowt

[Allseasons-Si]

WTF!!!

 

the lava flow has stopped,is the chamber sucking it back for a eruption?

at present

[karyo]

I think the earthquakes have blocked the fissure. It was going strong until the last earthquake. It is not due to magma running out as then it would slowly die out. This seemed turning off like a switch!

[summer fun]

HI John

 

Do you think the last big quake has caused the caldera to collapse over the chamber thus effectively cutting off the supply of magma? 

 

 

If only they had nigh vision on the cams as well. we would be able to see the glacier to check nothing has changes there,

Yes i know john,feeling slightly worried atm,there is more than one hair stood at the back of my neck now.

Does it also not seem that now the lights from the Doppler are fading. 

 

OH wait they have gone.

[Polarlow]

Doppler radar lights very faint must be smoke and Ash !!! Looks like it blew ????
