Update 5 March: The science committee says that the volcano, which started erupting on 10 October, has died. The decision to make the announcement was agreed unanimously by the experts. In what must have meaning for the scientists, if not for the public, they say that the "eruptive process continues" and that scientific vigilance will [...]

Capitanía Marítima de Santa Cruz de Tenerife has reduced the maritime exclusion zone to a radius of just half a mile around the volcano emission point south of La Restinga. The sector is defined as a circle drawn with its centre at latitude 27-37.18 N and longitude 017-59.58W – as per the map below. The decision was taken in the wake of Pevolca's reduction of the alert level. In the newly reduced exclusion zone, all fishing and water sports, including diving, are banned. Any navigation within the zone must be with prior authorization from the Capitanía Marítima. JAA

Finally, after weeks of calm, El Hierro's eruption alert status has been returned to green. Pevolca and the Canarian Government have now removed the yellow alert, thereby confirming the return to normality ... and the island's survival after months and months of tension with the Las Calmas sea eruption. In the end, there was no new island, no new land mass, but El Hierro is the youngest Canarian island. Who knows what will happen in future weeks, months and years ... or even decades. The yellow alert has, for the moment, been kept for the sea area around the volcanic cone.

 It's back. The Frontera area had five tremors this morning, one of which was felt by the public. Within just 25 minutes between 07.18 and 07.43, the first four were registered between 1.6 and 2 on the Richter scale; the fifth was registered at 12.45 with a magnitude of 2.9 and an epicentre on the coast near to the Valle del Golfo. All occurred at a depth between 17 and 20 km, says IGN.

Actualidad Volcánica de Canarias (AVCAN), linked to the Asociación Vulcanológica de Canarias, has confirmed that the tremors indicate a magmatic origin and, naturally, a possible pressurization which, if it were to continue, would cause more seismic activity in the area. JA
