The crater of Pu’u O’o volcano in Hawaii has partially collapsed prompting civil defense alerts of a coming lava flow potential on the flanks of the volcano.

A multiple week long earthquake swarm has taken place at Kilauea, along with a rise in the greater magma chambers levels spilling over the top of the crater a few days ago.

Today, the volcano next to Kilauea (Pu’u O’o’) partially collapsed.

A similar event occurred in Hawaii the week prior to Japan’s megaquake in March 2011, Pu’u O’o drained, followed 5-6 days later by the M9.0 in Japan.
