VC-commenters arjanmm and Alison noted at 14:54 and 14:59 UTC today that some tremor was going on at our famous Canarian friend El Hierro. A clear rise in tremor, combined with several earthquakes were seen at the seismic stations on El Hierro, most notably on the CHIE-station.
Diario El Hierro (the local newspaper) has already posted a news item about the renewed activity on their island, stating that “an important seismic reactivation” has occurred at their volcano. They state that up to now, 30 earthquakes between M1.9 and M2.6 have been measured, making this a significant reactivation event indeed. A quick look on the list of EQ’s published by the IGN tells that so far (19:00 UTC) 55-60 EQ’s between M1.7 and M2.7 have been detected.
dfm has been very quick in 3D-plotting the renewed activity as well, as can be seen below. Thanks for that dfm and others!
Whether this new activity will lead to a baby brother or sister of Bob will remain to be seen, but it is sure that something is on the move again deep below El Hierro. As we have seen with the birth of Bob, there don’t need to be many shallow quakes in an area for a new fissure to open and allow the lava to erupt, whether this is on the seabed or not.
We should definitely keep an eye on what is happening, since the combined knowledge of all commenters and the powers of data processing by some of them, can surely help in painting a picture of what is actually going on, even though official sources might sometimes disagree. In Bobs case, several commenters have had a better grip of the reality at times than official sources, so don’t be afraid to speak out if you think you have found something important.
And finally, a short note to all readers and commenters; try not to swamp the IGN website or any other site that locals might need to get the information they need. If possible, quote text and provide the source, and upload images and post the link to the uploaded image instead of linking directly to the source to prevent overloading of those websites. With that in mind, please don’t forget VC’s special section about Bob/El Hierro:
