It is possible to predict fairly accurately when an earthquake is due.

Methods of PredictionMethods of Prediction
Mostly, scientists today predict earthquakes by looking at areas where pressure is building up and, judging by the recency of the last quake, guessing at the general date of the next.
Satellite radar can sense any plate movement, even at the slow rate of 1mm per year.

Satellites may be able to predict earthquakes by sensing the infra red light that is produced by the pressure build up in the rock.
Scientists may be able to use the miniscule fluxuations in earth’s magnetic field that occur just before major earthquakes.

proximity to plate boundaries
The further a place is from a boundary, the less likely it is to have a major earthquake.
type of plate boundary
Most major earthquakes occur near convergent plate boundaries.

The blue lines mark the convergent plate boundaries which I think are most likely to cause earthquakes soon because they havd not had a major quake recently.

ReasonsReasons
I believe that these 10 countries are most likely to have a major earthquake soon because they are:
on convergent boundaries
have had large earthquakes in the past
have not had a significant earthquake in the past year.

The United States
I believe this because:
the U.S.’s north west coast is on a convergent boundary
they have constant small quakes
that part of the boundary has not had as many major quakes as the rest of the convergent boundaries
