Lol I so agree and I miss Elenin and end of days, catastrophe and fear mongering!
Let the East Coast ending Volcano watch begin!

ps El Hierro isnt the one that will cause the volcano to go into the sea and create a huge tsumani, is it? I really hope not.
Tsunami scenarios In a BBC Horizon programme broadcast on October 12, 2000, two geologists (Day and McGuire) cited this rift as proof that half of the Cumbre Vieja had slipped towards the Atlantic Ocean (Day et al., 1999; Ward and Day, 2001). They suggested that this process was driven by the pressure caused by the rising magma heating water trapped within the structure of the island. They hypothesised that during a future eruption, the western flank of the Cumbre Vieja, with a mass of approximately 1.5 x1015 kg, could slide into the ocean. This could then potentially generate a giant wave which they termed a "megatsunami" around 650–900 m high in the region of the islands. The wave would radiate out across the Atlantic and inundate the eastern seaboard of North America including the American, the Caribbean and northern coasts of South America some six to eight hours later. They estimate that the tsunami will have waves possibly 160 ft (49 m) or more high causing massive devastation along the coastlines. Modelling suggests that the tsunami could inundate up to 25 km (16 mi) inland - depending upon topography. The basis for Ward and Day (1999) modelling the collapse of a much larger portion of the western flank than the currently visible surface fissures suggest is unstable, was based on geological mapping by Day et al. 1999. In this paper they argue that a large part of the western flank has been constructed in the scar of a previous collapse and therefore sits upon unstable debris.
We’ve been closely watching the earthquake swarm at the Canary Island’s El Hierro since the middle of the summer and it looks like there has been a dramatic increase in the number and intensity of the seismicity at the volcano. Since mid-July, the small island, which is the top of a shield volcano built by the Canary Hotspot, has registered over 8,000 earthquakes

No it is not. That is Cumbre Veija, and even that won't cause a tsunami on the East Coast of Murka.
Oops should have read further. Sorry.
By the way those two 'geologists' modelled this by dropping rocks into a closed tank. Not exactly a good model of the Atlantic!
Have a read of thisedit on 8/10/2011 by PuterMan because: (no reason given)
The upper limit of his modeling study shows that the east coast of the U.S. and the Caribbean would receive waves less than 3 meters high. The European and African coasts would have waves less than 10 meters high. However, full Navier-Stokes modeling of the same La Palma failure, brings the maximum expected tsunami wave amplitude off the U.S. east coast to about one meter.
