4—GOD STRIKES THE ENVIRONMENT MANKIND PROTECTS: Revelation 8:5-7—
Most likely volcanic eruptions from the quake shoot water and steam with ash upward into the atmosphere, which comes back down as hail that looks reddish in color. These eruptions may also ignite the forests, so 1/3 of all trees are destroyed.
5—GOD SHOWS WHAT HE CAN DO TO THE OCEANS: Revelation 8:8—
An extinction-level asteroid or meteor plunges down to strike the ocean and devastates 1/3 of all ships, perhaps by tsunamic tidal waves. God then turns the oceans to blood or lets the normal process of red tide poison the seas.
