KILAUEA, Hawaii - USGS recently released their overview of Kilauea Volcano's 2018 lower East Rift Zone eruption and summit collapse. 

It all started on April 30, when the long-term Pu'u 'O'o eruptive vent collapsed and magma began moving downrift toward Puna.

By May 3, the Volcano Alert Level was raised to a Warning. The next day, a 6.9 magnitude earthquake rocked the south flank of Kilauea. After that, there were explosive events, Fissure 8 was reactivated and lava began to flow out, and there were near-daily summit collapse events.

By August, Fissure 8 activity had significantly decreased, and at the end of the month, ocean entry was no longer active.

On October 5, over five months later, the Kilauea Volcano Alert Level was lowered to an Advisory. 

It wasn't until March 26, the following year, that the Volcano Alert Level was back to Normal.

Here are some facts and statistics from USGS:

  • largest lower East Rift Zone eruption and summit collapse in at least 200 years
  • 13.7 square miles of land inundated by lava
  • 875 acres of new land created by ocean entries
  • 716 dwellings destroyed by lava 
    • 30 miles of roads covered by lava
    • 1 billion cubic yards of lava erupted
  • Magnitude-6.9 south flank earthquake on May 4, the largest in Hawaii since 1975
  • 62 summit collapse events, May 16 to August 2
  • 12 ash-producing explosions May 16-26
