- Yesterday ended with 24 volcanic earthquakes in total
- The image below shows a new (short) period with volcanic earthquakes. The strong tremor at the start tells us that the magma reached other channels. The hypocenter depth remained however in the 16 to 18 km layer.
- The 3th map shows the deformation of the island and as could be expected with such a crisis, the activity is also confirmed in the deformation which is a mainly eastern and upwards (center and right parts of the graph)
- Another map shows the location of the epicenters of todays earthquakes. No real change vs yesterday and 2 days ago.

Als ik kijk naar het stukje van 2013-03-24 13:24 , lees ik de conclusie dat een eruptie boven het bevings gebied zou moeten komen.quote:2013-03-24 13:24 UTC
- Believe it or not, but already 104 M2+ volcanic earthquakes below El Hierro so far today, thats more activity than yesterday at this time of the day. Yesterday ended with 165 volcanic earthquakes.
- Hypocenters in the 15 to 17 km layer
- When pinting the center of the current action (last 15 earthquakes) on a Google earth map, we arrive at a seabed depth of 1800 meters
2013-03-24 08:48 UTC
- Our daily M2.5 earthquake list looks like only the Canary Islands exist today.
- The scientists who said a couple of days ago that this crisis wont end in an eruption as the strength was not enough to reach the seabed, may start to write a second opinion. The crisis goes on and is a lot stronger than the last episode. Some more facts :
- 62 M2+ earthquakes so far today = hundreds of volcanic earthquakes of we would also count the weaker ones (which IGN did at the start in 2011)
- Hypocenter or focal depths (breaking point in the layers below the island) 16 to 17 km depth (4 to 5 km deeper than yesterday).
- The epicenter locations have shifted a little to the West (main reason for the deeper hypocenters).
- Deformation statistics are very spectacular as the Sabinosa GPS has been forced upwards with 2 cm the last 24 hours (see image University of Nagoya below ). The same GPS was also forced 1 cm to the East. North/South remained the same.
quote:2013-03-23 19:15 UTC
- 134 earthquakes so far today (strongest activity since the start of this seismic crisis)
- Hypocenters gradually shallower (12 to 14 km layer) which indicates that the magma is reaching cracks in higher levels. Too far out in the sea to generate a Surtseyan eruption if a new vent would emerge (seabed depth 1000 to 1300 m)

Als ik kijk naar het stukje van 2013-03-24 13:24 , lees ik de conclusie dat een eruptie boven het bevings gebied zou moeten komen.
Als ik kijk naar de eerste eruptie site, van La Restinga, dan zaten de bevingen grotendeels onder het eiland en zeldzaam ronde de plek van de eruptie.
De recentelijk genoemde 2e eruptie plek daar in tegen zat wel in de buurt van de west kust. De bij behorende bevingen zaten iets te noord westen van de eruptie plek.
Als je gaat kijken naar het genoemde centrum van de huidige bevingen, zee bodem zit daar op 1800 meter, dan zou een eruptie mogelijk een eindje verder naar het zuiden (en ietsie oostelijker) te voorschijn komen.
Dit zal dan nog altijd verder westelijk zijn dan de laatste eruptie. En dat is dan ook gelijk weer een heel stuk dieper. En waarschijnlijk zullen we daar niets van gaan zien door de diepte.
En daar schreef EarthQuake Report ook al over

Exact. Dat is wat ik eigenlijk wilde melden.quote:Op maandag 25 maart 2013 10:38 schreef Jumparound het volgende:

- A few minutes ago we had the strongest earthquake from this crisis, a M4.1 at 16 km depth (same area out in the sea). The image below shows this earthquake on the seismogram and not a piece of art . Just before the 4.1 one, we had a M3.4 one, also at a depth of 16 km.

- This is without any doubt one of the most powerful earthquake sessions since the start of the eruptive process at El Hierro. Readers will be surprised about the number of very powerful events when they are listed by IGN.
Luckily for El Hierro everything is happening out in the sea at a depth of +1500 meter. A volcano has however NO guarantee at all that the action will stay in that area. The same happened during the eruption in 2011 when the magma vent was located in a totally different area than the earthquake epicenters. This was however an exception.

- Also, according to them, there is a 75% chance of a M4.3+ earthquake .
Ik kan er echter niet uit herleiden of dit een meting is uit het zuiden bij La Restinga of het noorden waar nu de bevingen zijn.quote:Bathymetry of the El Hierro submarine volcano generated in March 2013 during the campaign Vulcano0313, promoted by the Spanish Institute of Oceanography.
