No one can avoid the day of the Lord (see study note on Isaiah 2:5–22).
the windows of heaven are open: This image is similar to the great flood in Noah's time (see study note on Genesis 7:11–12).
the foundations of the earth are shaken: An earthquake often marks a theophany, which is a physical sign of God's presence (see also Isaiah 6:4; 13:13; 19:1).
