(Psychological / emotional perspective)
An erupting volcano usually signifies that we are not in control of a situation or of our emotions â of which there may be a hurtful release.
If the lava is more noticeable, feelings will run very deep.
If the lava has cooled there has been a deep passion that has now cooled off.
If the explosiveness is more noticeable, and seems more recent, anger may be more prominent.
