On are moving away from each other.

On May 17th, 2018, the Kilauea volcano in Hawaii erupted, potentially risking many lives.
The eruption took place at 4:15, local time on Thursday where the volcano began to discharge ash and spew out lava. Residents that lived nearby were evacuated from their homes. But by the end of the eruptions, multiple houses and other structures were either partially destroyed or reduced to nothing.
Kilauea is a shield volcano meaning it’s found at constructive plate boundaries where the plates are moving away from each other. However, Kilauea is made from a hot spot. A hot spot is where magma wells up through a crustal plate. There are 2 reasons why this may have happened. The first is that the magma was extremely hot, or the crust is weak and brittle
Kilauea has been erupting constantly since 1983, but this eruption was incredibly explosive and followed after a large earthquake. The area near the volcano is very used to eruptions as they are very frequent. However, the involvement of an earthquake enhanced the effect of the volcano creating an explosive eruption.
People have been advised not to return to their homes due to the high amounts of sulphur in the air and fissures in roads and other places
