1400 years ago nobody knew that earthquakes precede eruptions however it was portrayed in the Quran.
Prediction of volcanic activity
Seismic activity (earthquakes and tremors) always occurs as volcanoes awaken and prepare to erupt and are a very important link to eruptions. Some volcanoes normally have continuing low-level seismic activity, but an increase may signal a greater likelihood of an eruption. The types of earthquakes that occur and where they start and end are also key signs.
