True or false: the number and the size of earthquakes decrease before a volcanic eruption.

The statement is True. Earthquakes identified with volcanic movement may deliver perils which incorporate ground splits, ground misshapening, and harm to artificial structures. There are two general classifications of seismic tremors that can happen at a fountain of liquid magma: spring of gushing lava structural quakes and extensive stretch seismic tremors.  

Earthquakes delivered by pressure changes in strong shake because of the infusion or withdrawal of magma (molton shake) are called spring of gushing lava structural quakes (Chouet, 1993). These seismic tremors can make land die down and can deliver huge ground splits.

These seismic tremors can happen as shake is moving to fill in spaces where magma is never again present. Well of lava structural seismic tremors don't demonstrate that the fountain of liquid magma will eject however can happen at whenever.

the correct answer is c
