Not by the USGS/NOAA they weren’t. Their analysis was, as usual, spot on. Small tsunamis (up to 0.7ft I think) were observed, but aafter the initial very large quake was analysed no significant tsunamis were predicted.

Until that analysis takes place the risk must be stated especially with a quake of that magnitude.

There has been a magnitude 7.2 quake in Haiti this afternoon, hopefully it is not nearly as serious as the 2010 quake (as it is further away from the capital), but I worry about the location and magnitude given the infrastructure of the country.

The situation is likely to be worsened by the arrival of TS Grace in a couple of days' time, though current forecast is for Grace, which has a limited circulation, to dump most of its rain on the N side of Haiti, away from the earthquake-affected zone.

Unfortunately Grace diverged from this prediction and has been drenching the earthquake zone

Death toll 2000 and rising - Haiti does seem to attract natural disasters.

And a magnitude 6.4 a short while ago.

This site shows the location and magnitude of quakes.   Quite a few lately - but I don't know if this is within the normal range?

You can zoom in on the map and see the exact point of each.  Quite a cluster in the centre of the island if you select '4+'

Yes, although I think some of those will be aftershocks from last month’s large quake. However  it does strike me as an anomalously high number of quakes. Having two that magnitude in a few weeks seems quite unusual but may be nothing more than coincidence (for want of a more scientific term!).
