The lava dome inside the crater of Mt St Helens Volcano continues to grow. A magnitude 3 earthquake hit the volcano yesterday at 5:22am, which caused a rockfall and sent an ash plume above the crater rim. The cause of the earthquake is unknown. Currently the rates of seismicity and ground-deformation are low.
