Your felt reports are very vital in
knowing how strong the shaking was in your area.
If a magnitude 5 earthquake 200 kilometers away
was strong enough to cracks walls in your house,
then there's a very good chance that the next
time there is a similar earthquake, 200
kilometers away, damage could be the same.
Knowing how the ground below you behaves is very
vital when it comes to the safety of your home
and your family. For our part, your report is
assigned a
Mercalli Intensity value and
Historical
Shake Intensity Maps are plotted. These show in a very
simple fashion the different levels of ground
shaking around the epicenter and in the
neighbouring region. You can also tell us about a
certain earthquake you might have felt several
years back.
