The timing of the San Francisco earthquake and the Azusa Street Revival are not coincidence. Below is one account, there are many more:

Meetings were transferred to the former African Methodist Episcopal
Church at 312 Azusa Street. During the next few days as they were
renovating the lumber store the first convert was recorded. One of the
women who were cleaning the building had one of the workmen down on his
knees and he was soundly converted before the place was opened.

On Easter Sunday morning (April 15th) Jennie Evans Moore took the
Asbery’s to Smale’s church. After the sermon, when Smale invited
testimonies. Jennie took the floor and told the congregation what had
taken place in the Asbery home and in Azusa Street. She then spoke in
tongues and the awed congregation heard Ruth Asbery give the
interpretation.

On Tuesday a reporter from the Los Angeles Times visited Azusa Street.
On the following day the paper carried the report of this visit. The
same paper led with a report of the San Francisco earthquake that
resulted in the death of 10,000 people.

Excerpt from the Stanley Frodisham prophecy from 1965:

http://www.propheciesfortoday.uk.com/listA.php?id=174

With great judgements will I plead with the population of this country. Great darkness is coming upon the countries that have heard My gospel but no longer walk in it. My wrath shall come upon them. The darkness shall be so great and the anguish so sore that men shall cry out for death and shall not find it. There shall be a lingering death, famine and great catastrophes.

The prophecy above is not the only one in modern times that I have come across that states the Lord is not pleased with his church and we will be judged to bring us back to him. It’s pretty clear in the Word of God concerning the sins of Israel.

Also from the Stanley Frodisham prophecy:

When I visit My people in mighty revival power, it is to prepare them for the darkness ahead. With the Glory shall come great darkness, for the Glory is to prepare My people for the darkness.
