Hi all,

My 2 cents.

Steve is right, this is just some sort of network glitch.

The youtube author does not have the foggiest idea of how the software 
the generates those charts works or how the national and global seismic 
networks work. He could have called anyone at CERI and asked for an 
explanation, Mitch would have been glad to tell him that the janitor 
pulled a cable or something like that.  All the author does is trap some 
RSS feeds and feeds them to his apps. The graphics are pretty but I 
suspect that he knows little about seismology and almost nothing of the 
monitoring systems.

It is almost impossible to hide an earthquake.  The global networks, 
many of them,  can detect earthquakes over magnitude 4 just about 
anywhere on earth.  The USGS has no monopoly on sensitive seismographs 
and certainly no control over any of us amateurs. No one knows more of 
the seismicity around my house than me.

The codes that generate those charts (helis)  are freely available 
on-line anyone can download and install them, anyone can get the global 
feeds and anyone can make a virtual global network.  If the author just 
took a minute to look at the source code he would understand just how 
difficult it would be to cut a quake out of the system.  These are 
distributed systems.  Everyone gets all the data in real time. CERI is 
just a (big) regional network.

Saludos,

Angel
