More, and yes there is another earthquake, at least according to Yahoo. http://asia.news.yahoo.com/041226/ap/d8774gj04.html
Like I said I really think it's just the Bangladeshis screwing up; it's either just the 8.5 Sumatra quake or one of the Andaman aftershocks, and because those quakes saturated their equipment they couldn't tell what was going on.
Neither NEIC or the Swiss Red Puma page have a quake in or near Bangladesh.
