Pele's surface lava has finally reached the steepest portion of the Pali and numerous breakouts sent lava coursing down the hill

The new website features interactive maps that display earthquake and monitoring data and you can view near-real-time data streams across all monitored volcanoes

The science of volcanology was changed forever, and today the risks from future eruptions anywhere in the world are lessened because of what happened on that fateful day.

The front portion of the lava delta collapsed recently, but dozens of lava rivulets have begun the rebuilding process.

Hawaiian Volcano Observatory has transformed stacks of paper earthquake records into digital squiggles.
