[data-issues] mag 9.5 bogus event in db

[Philip Crotwell]

Hi

I suspect you just store what you are given, but thought I would point
this out just in case. It is very unlikely that this was really a
magnitude 9.5.

1 	2006-10-09 19:06:18.0 	18.974 	121.117 	11 	 9.5 	MS 	ISCCD 	MAN
	MAN 	249 	22 	LUZON, PHILIPPINE ISLANDS

I looked at the ISC website and they also have the 9.5 magnitude, so
your db is correct in that sense. I guess the ISC can argue that MAN
(whoever that is) contributed it, and so they should publish it. But
it seems like a little extra care should be given to really large
magnitudes as people are often interested in the biggest earthquakes.
As it stands now, the "biggest" earthquake in the database this decade
is not really a very big earthquake. :(

The reason I noticed this is that REV picks up on this event and so
the biggest circle on our map is not real. I am going to manually
reject this event in REV, so not a big deal for me, but might continue
be for others.

I will also send something to the isc.

thanks,
Philip

PS There was a 9.9 in Bolivia in 1999, likely same type of issue.
