Alert status raised to yellow – “An eruption could be imminent,” says one website.
Strong deformation detected
According to INVOLCAN, significant and rapid inflation has been measured in the southern part of the island of El Hierro during the past two days.
This deformation is most likely caused by the accumulating magma underneath, and is much faster than that observed last year 2011 prior to the eruption south of La Restinga.
A “yellow alert” has been declared for the El Verodal or the western tip of the island and the southern area in the El Julan bay, where most quakes are located, and an eruption could be imminent.
Yesterday, 26 June, saw a record number of 234 quakes greater than M1.4,
most of them larger than M2 and 6 larger than M3, all at about 18-20 km depth.
According to the extinction protocol website, about 580 earthquakes were registered from Monday to Wednesday. Thirty of them greater than magnitude 3 on the Richter scale.
“The entire island has risen by 4-5cm and moved by 3cm since the latest magma movement!,” says analytical chemist Hans Schneider. “Glad not to be there, for sure!”
