Bystanders spooked by strange goings on at crucifixion

As reported in Matthew:

From the sixth hour until the ninth hour darkness came over all the land. About the ninth hour Jesus cried out in a loud voice, “Eloi, Eloi, lama sabachthani?”—which means, “My God, my God, why have you forsaken me?” When some of those standing there heard this, they said, “He’s calling Elijah.” Immediately one of them ran and got a sponge. He filled it with wine vinegar, put it on a stick, and offered it to Jesus to drink. The rest said, “Now leave him alone. Let’s see if Elijah comes to save him.” And when Jesus had cried out again in a loud voice, he gave up his spirit. At that moment the curtain of the temple was torn in two from top to bottom. The earth shook and the rocks split. The tombs broke open and the bodies of many holy people who had died were raised to life. They came out of the tombs, and after Jesus’ resurrection they went into the holy city and appeared to many people. When the centurion and those with him who were guarding Jesus saw the earthquake and all that had happened, they were terrified, and exclaimed, “Surely he was the Son of God!”

As reported by Luke:

It was now about the sixth hour, and darkness came over the whole land until the ninth hour, for the sun stopped shining. And the curtain of the temple was torn in two. Jesus called out with a loud voice, “Father, into your hands I commit my spirit.” When he had said this, he breathed his last. The centurion, seeing what had happened, praised God and said, “Surely this was a righteous man.” When all the people who had gathered to witness this sight saw what took place, they beat their breasts and went away. But all those who knew him, including the women who had followed him from Galilee, stood at a distance, watching these things.
