Data Update 28/11 – 16:48 UTC
- Medium to strong harmonic tremor
- 18 earthquakes since midnight. The number of earthquakes has been picking up speed and strength during the first hours of the afternoon.
- The strongest earthquake was a M 2.9 @ 13:32
Update 28/11 – 14:54 UTC
The Telefonica – Movistar managers found out this morning that many webcam screenshots circulated on the internet (avcan, ER, our Picasa site, etc). One of them saw the light and could convince the management to add the Movistar logo in the screen. As long as not everybody starts putting his logo on it, we can live with it. It might encourage Telefonica to replace the present cameras with combined HD / Infrared cameras). Update 16:12 UTC : The camera operators are probably also looking at ER as after writing the earlier text, Movistar disappeared again from the screen and the AXIS ad was added to the right, as if saying : "if you want to criticize our webcam material, address the right people 
! "

At earthquake-report.com, we are so happily surprised that our readers continue to interact at max. with our site.
- Yesterday, we had a lot of readers sending screenshots from what happened on the webcam.
- Joke Volta, a local resident who became gradually a continuous source of information.
- Ian Carson, who changed his California vacation plans to El Hierro after reading our reports, and sending us info and beautiful images from what happened. Unfortunately, Ian will have to leave later today for his flight back to the UK.
- Today, 2 other people, Marietta and Dave (2 different families who do not know each other) offered to send interesting information to earthquake-report.com when they will be at La Restinga the next couple of weeks.
On behalf of all of our readers, we do thank all these present and future volunteers for their contribution.
The internet as it should be used.
