The horror fall occurred on the one-year anniversary of Kilauea erupting in May 2018, sending lava into residential communities on Hawaii Island.
A man was critically injured late Wednesday after climbing over a safety railing at Hawaii Volcanoes National Park and falling 70 feet from Kilauea volcano's caldera.
"Visitors should never cross safety barriers, especially around risky and destabilized cliff edges", John Broward, chief ranger at Hawaii Volcanoes National Park, said in a statement. He warned that crossing safety barriers could result in serious injuries or death.

According to officials, the ship is scheduled to leave port before midnight on May 3. The church's media centre was not immediately available for comment.
"At approximately 9:00pm, the man was found alive but seriously injured on a narrow ledge about [20 metres] down from the edge". He was taken by helicopter to the Hilo Medical Center to be treated for his injuries. On Thursday his condition was upgraded to stable.
"He obviously is doing remarkably well for his fall", Hawaii County Fire Department Battalion Chief Matthias Kusch told the station. But it said in a statement that Kilauea "ranks among the world's most active volcanoes and may even top the list".
According to the Hawaii Tribune-Herald, a less fortunate person died in this volcano in October 29, 2017.
Volcanic eruptions hit Hawaii a year ago.
Kilauea dominated headlines last summer, when it spewed lava, ash and "vog"-a unsafe mix of water, carbon dioxide and sulfur dioxide-during a period of intense activity".
