Check these pics of the sea by El Hierro, Canary Islands, Spain, says reader from the UK.
Since July there have been over 11,000 tremors (eleven thousand!)
They had another 50 quakes today, biggest one 4.4 Richter; could be major eruption at a moment’s notice.
Quakes in the northern waters as well as the southern ones.
Depth of eruptions now only about 150 metres.
It now appears that there is a rift with several eruptive points, coming closer and closer to the southern coast.
There are also many eruptions along the northern coast, where 50,000 years ago a huge slice of the island slipped into the sea.
Anxious times for all residents of this lovely little island.
I wonder what is heating the seas.
