How is energy of an earthquake stored before the earthquake?
the energy is stored before the earthquake in the exinstle manner of the earthquake. The exinstile manner is below the earthquake where the rumble happens.

The cause of St Helens Volcano Eruption in the year 1980 was a 5.1 magnitude earthquake. The volcano didnt erupt for 120 years before this eruption .. so all the magma in the magma chamber had alt of pressure and was pushed out. the volcano was in a position where plates move.

What comes before during and after and earthquake?
Before an earthquake nothing perceptible to humans happen. Several types of animals act up though. During a earthquake the ground trembles. Depending on the magnitude this might be anything from a light tremble to a violent shaking. Most of the time nothing happens after an earthquake, but sometimes there is an aftershock, which is another earthquake of a lesser magnitude.
What happens before the eruption of the Kilauea volcano?
When the magma gets close to the surface, the gases dissolved in it start to come out, forming gases which help the magma rise further and erupt. If there is a lot of gas in the magma, it may explode as the gases expand. There may also be triggers like a landslide that uncaps the magma reservoir (like at Mt. St. Helens in 1980) or an interaction with groundwater that causes an explosion.
How is the energy that causes an earthquake stored before the earthquake happens?
It is stored in the form of elastic strain (also known as elastic potential energy) in the rocks of the crust as they deform under stress.
