Are the abundance of earthquakes and the omission by preachers of any mention of the Antichrist among the signs of the Day of Judgment?

"Frequent earthquakes are among the minor signs of the Hour, according to the Prophet, peace and blessings be upon him: "The Hour will not be established until knowledge is taken away and earthquakes become frequent." As for the disappearance of the mention of the Dajjal and imams abandoning his mention on pulpits, there is a hadith concerning this whose authenticity scholars have differed upon: "The Dajjal will not appear until people cease mentioning him, and until imams abandon mentioning him on pulpits."
