Well basiclly everywhere where there are faults and plate boundaries. So basiclly anywhere in the world. Since earthquakes are created by stress in faults or plate boundaries being released as seismic waves then everywhere in the world is at risk of an earthquake. Some places such as California, Japan, Indonesia, China, Greece, India, Nepal, Alaska, etc. are at higher risk of a major or minor earthquake mostly because there near or on a plate boundary thats more explosive or dangerous. As for everywhere else in the world many are at risk of small quakes such as 3's or 4's which are a decent size. So the answer to your question is that everyplace in the world is at risk of an earthquake.
The equator experiences equal day and night as the summer solstices has longest days in northern side and the winter has longest in the southern side.
Explanation:
As the summer have the solstice period in the northern hemisphere, the areas in the north gets most of the heat and sun days as that of the southern hemisphere and the reverse is true for the winter solstices that has maximum day in the south and less in the northern hemisphere as sun rays don't pass the 66.5 degrees latitude.
