Mishkat al-Masabih

Ubayy bin Ka'b (may Allah be pleased with him) narrates: It was the practice of the Prophet (peace and blessings be upon him) that when two-thirds of the night had passed, he would stand up and say: "O people! Remember Allah, remember Allah, the earthquake is about to come, immediately after it another earthquake is about to come, and death has come with its hardships, and death has come with its hardships." Its chain is weak, narrated by al-Tirmidhi.
