Particle Help

So when the player stands still I want to still spawn the particles. But every time they move it creates more and more particles. Is there a way to make it so when they move they spawn a certain amount and when they stop moving it still displays the other amount and not add more particles?
Thank you!

Code (Text):

    @EventHandler
public void onPlayerMove5(final PlayerMoveEvent e) {
    if (ParticleAPI.volcanoash.contains(e.getPlayer().getUniqueId())) {
   
        new BukkitRunnable() {
            @Override
            public void run() {
                if (ParticleAPI.volcanoash.contains(e.getPlayer().getUniqueId())) {
                    ParticleEffect.EXPLOSION_NORMAL.display(10, 15, 20, 0, 0, e.getPlayer().getLocation().add(0,2.5,0), 10);
                    //ParticleEffect.EXPLOSION_NORMAL.display(10, 15, 20, 0, 0, e.getPlayer().getLocation().add(0.3,3,0.3), 70);
                    //ParticleEffect.EXPLOSION_NORMAL.display(10, 15, 20, 0, 0, e.getPlayer().getLocation().add(0.3,3,0.3), 70);
                    ParticleEffect.LAVA.display(10, 40, 1000, 0, 0, e.getPlayer().getLocation().add(0,2.6,0), 5);
                } else if(!(ParticleAPI.volcanoash.contains(e.getPlayer().getUniqueId()))) {
                    e.setCancelled(true);
                   
                }
            }
        }.runTaskTimer(Hub.plugin, 0, 20);
   

}
}
