Hombre que cunda el panico, que hablamos de erupciones y algunos se piensan que se acaba el mundo, el Hekla ha entrado en erupción varias veces y no ha pasado nada, creo que la ultima en 1991.

Realmente lo importante no es tanto que entre en erupción, sino la cantidad de cenizas y gases que emite a la atmosfera y sobre todo la altura a lo que lo hace.

Buscando por la internet, una foto de una erupción del Hekla.

Concretamente la última erupción del Hekla se produjo entre el 26 de febrero y el 8 de marzo del año 2000, sin aparentes riesgos de ningún tipo para la actividad humana. Sin embargo, fue el preludio de lo que los geólogos habían ido avisando, y se intensificó el estudio de la situación de los volcanes en Islandiua. Esto que está ocurriendo estos días era de esperar de un momento a otro.

otro detalle es que parece que la erupción esta adquiriendo un caracter estromboliano
la altura de la pluma tiende a disminuir 3000m ahora frente a los 7000m que tenia antes ..y la lava es mas fluida

Donde ves la lava? Y los datos de la pluma ?

Links links !! Necesito informacion !!

In what is sounding like a bit of a broken record, the eruption at Eyjafjallajökull is still going. However, we might be beginning to see some changes in the style of volcanism - even the first suggestion of lava flows at the new crater. As mentioned yesterday, since the eruption became subglacial, we've been seeing eruptions where water - in this case glacial meltwater - has been playing a very important role, creating phreatoplinian or surtseyan style eruptions driven by steam explosions. Although the ash is andesitic, most of the explosiveness of the eruption likely lies with the water. The ash plume at the volcano this morning is smaller than 3,000 meters / 10,000 feet and after watching some of the show that Eyjafjallajökull put on last night, I would venture to say that much of the activity (Icelandic) is strombolian, with explosions (some large) of lava at the vent, throwing incandescent ash and bombs. The explosions are coming from gases escaping from the magma in the conduit and these bombs can travel hundreds of meters - but it is less likely to produce the large ash plumes we have been seeing. All of this implies to me that right now, there is less meltwater entering the crater area. This could change quickly, but this eruption has become a little more like Ruapehu in 1995-96 with abundant small explosions and ash plumes as the andesite erupts.

Así está esto:



Entro a clase en 5 minutos, ponedme al día plisss
No consigo acceder a las webcams del Eyjafjallajökull. ¿Ha vuelto a entrar en erupción?

Si no lo traduces entero, al menos podrias poner un resumen gracias.

No he podido leer en todo el dia este topic y ahora tampoco puedo, asi que pongo una imagen y pido perdon si esta repetida... es para que veamos claro del sistema volcanico que tenemos entre manos...

Perdon por el OffTopic...
