Why lower the antenna?

It is only in comparison with December's devastating tsunami
that left over 180,000 dead, that Monday's 8.7 earthquake off the
coast of Sumatra can be considered relatively minor.

Indeed, the lack of any response by the Bangladeshi
authorities in the wake of the tsunami warning that was issued
shortly after the quake was detected is very worrisome. It is
clear that, even after the devastation of December, we did not
have any procedure or system in place to warn coastal populations
and ensure their safety in the event that there had been a
tsunami.

This is unacceptable. Tsunami or earthquake is a very real
threat and the damage caused by one can be greatly reduced if
there are simple and clear guidelines and procedures in place.
The fact that there have been two major earthquakes in the region
in a matter of months should be a wake up call to the authorities
to institute a procedure immediately.
