Answer to Question 1

For triangulation, one needs at least three seismic stations and their traveltime graphs. The distance from the earthquake epicenter for each station can be determined by the arrival time difference of P and S waves. This distance can be in any location at all, so a circle around the station with a radius of the distance can be drawn for each station. Where these circles intersect is the epicenter of the earthquake.

Answer to Question 2

Around the circum-Pacific belt of plate boundaries.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
