Earthquakes are not a result of disobedience, but a sign of the end of the age. God's method of punishing the nation of Israel allows us to see how God works among men. His method of punishment for their disobedience is clearly seen in Deuteronomy 28:15, "But it shall come to pass, if thou wilt not hearken unto the voice of the Lord thy God, to observe to do all his commandments and his statutes which I command thee this day; that all these curses shall come upon thee, and overtake thee..." . The numerous curses continue on through verse 68 without a single mention of an earthquake! Earthquakes are reserved for a sign of the coming of Jesus and that this current age is coming to an end. His desciples said in Matthew 24:3, "...Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?" Jesus answered in verse 7 by saying, "For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places."
In this present age we can rejoice in the freedom that we have from the law. Galatians 3:13, "Christ hath redeemed us from the curse of the law, being made a curse for us ... ." Earthquakes are more frequent and more powerful than ever. The end of the age is near and, for those of us who look forward to being with our Lord and Saviour, this is another reason to rejoice.
"For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air: and so shall we ever be with the Lord." (I Thessalonians 4:16,17)
