What does the Bible say about earthquakes?

Matthew 24 (KJV)
⁴And Jesus answered and said unto them, Take heed that no man deceive you.
 ⁵For many shall come in my name, saying, I am Christ; and shall deceive many.
 ⁶And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet.
 ⁷For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places.
 ⁸All these are the beginning of sorrows.

Mark 13
 ³And as he sat upon the mount of Olives over against the temple, Peter and James and John and Andrew asked him privately,
 ⁴Tell us, when shall these things be? and what shall be the sign when all these things shall be fulfilled?
 ⁵And Jesus answering them began to say, Take heed lest any man deceive you:
 ⁶For many shall come in my name, saying, I am Christ; and shall deceive many.
 ⁷And when ye shall hear of wars and rumours of wars, be ye not troubled: for such things must needs be; but the end shall not be yet.
 ⁸For nation shall rise against nation, and kingdom against kingdom: and there shall be earthquakes in divers places, and there shall be famines and troubles: these are the beginnings of sorrows.
 ⁹But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: and ye shall be brought before rulers and kings for my sake, for a testimony against them.
 ¹⁰And the gospel must first be published among all nations.

Luke 21
⁷And they asked him, saying, Master, but when shall these things be? and what sign will there be when these things shall come to pass?
 ⁸And he said, Take heed that ye be not deceived: for many shall come in my name, saying, I am Christ; and the time draweth near: go ye not therefore after them.
 ⁹But when ye shall hear of wars and commotions, be not terrified: for these things must first come to pass; but the end is not by and by.
 ¹⁰Then said he unto them, Nation shall rise against nation, and kingdom against kingdom:
 ¹¹And great earthquakes shall be in divers places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven.

Acts 16

Revelation 6
¹²And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
 ¹³And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.

Revelations 8
³And another angel came and stood at the altar, having a golden censer; and there was given unto him much incense, that he should offer it with the prayers of all saints upon the golden altar which was before the throne.
 ⁴And the smoke of the incense, which came with the prayers of the saints, ascended up before God out of the angel's hand.
 ⁵And the angel took the censer, and filled it with fire of the altar, and cast it into the earth: and there were voices, and thunderings, and lightnings, and an earthquake.
 ⁶And the seven angels which had the seven trumpets prepared themselves to sound.

Revelation 11¹And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein.
 ²But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months.
 ³And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.
 ⁴These are the two olive trees, and the two candlesticks standing before the God of the earth.
 ⁵And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed.
 ⁶These have power to shut heaven, that it rain not in the days of their prophecy: and have power over waters to turn them to blood, and to smite the earth with all plagues, as often as they will.
 ⁷And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them.
 ⁸And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified.
 ⁹And they of the people and kindreds and tongues and nations shall see their dead bodies three days and an half, and shall not suffer their dead bodies to be put in graves.
 ¹⁰And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth.
 ¹¹And after three days and an half the spirit of life from God entered into them, and they stood upon their feet; and great fear fell upon them which saw them.
 ¹²And they heard a great voice from heaven saying unto them, Come up hither. And they ascended up to heaven in a cloud; and their enemies beheld them.
 ¹³And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand: and the remnant were affrighted, and gave glory to the God of heaven.
 ¹⁴The second woe is past; and, behold, the third woe cometh quickly.
 ¹⁵And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
 ¹⁶And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
 ¹⁷Saying, We give thee thanks, O LORD God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
 ¹⁸And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
 ¹⁹And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.

Acts 16
²⁵And at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard them.
 ²⁶And suddenly there was a great earthquake, so that the foundations of the prison were shaken: and immediately all the doors were opened, and every one's bands were loosed.
 ²⁷And the keeper of the prison awaking out of his sleep, and seeing the prison doors open, he drew out his sword, and would have killed himself, supposing that the prisoners had been fled.
 ²⁸But Paul cried with a loud voice, saying, Do thyself no harm: for we are all here.
 ²⁹Then he called for a light, and sprang in, and came trembling, and fell down before Paul and Silas,
 ³⁰And brought them out, and said, Sirs, what must I do to be saved?
 ³¹And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.
 ³²And they spake unto him the word of the Lord, and to all that were in his house.
 ³³And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway.
 ³⁴And when he had brought them into his house, he set meat before them, and rejoiced, believing in God with all his house.
