When a massive earthquake strikes, no sane seismologist would try to trace the rumble of a passing truck amid the
noise of the aftershocks.
(According to that model, the number and
size of aftershocks generally decrease over time in a predictable way.)
The team's analysis uses a model that simulates how series
of aftershocks unfold — statistics that were first described by a Japanese seismologist in the 1890s.
Even if the bolstered buildings survive an earthquake, thereby protecting the people inside, many challenges may follow in its aftermath, not least the
potential of an aftershock like the one that struck Nepal on May 12 to knock down already damaged buildings.

The American Red Cross recommends that in the
event of aftershocks, persons should move to open spaces away from walls, windows, buildings, and other structures that may collapse, and should be alert to the danger of falling debris.
Since the proximate
cause of an aftershock is the main shock / earthquake, an aftershock is not considered a new event, but rather an extension of the original main shock / earthquake.

The assignment aims at gaining a better and more detailed understanding of the rupture process based on the aftershocks, and defining the rupture surface more precisely based on the
distribution of the aftershocks.
A magnitude 4.7 foreshock preceded the quake by about 20 hours, and
dozens of aftershocks were detected as well.
As with all major quakes, the New Madrid quakes spawned a

Conversely, a series
