Today, March 19th, marks the second anniversary of an explosion within Halema‘uma‘u Crater that heralded the start of a new eruption cycle, the first at Kilauea’s summit since 1982. That eruption continues.
Surprisingly, this eruption was not preceded by traditional indicators, such as earthquakes and ground swelling. Also unusual, this new summit eruption occurred without interrupting activity on the volcano’s east rift zone, which has been erupting nearly nonstop since 1983.
Although lava is frequently visible deep within the summit vent, there are no significant eruptions of ash or spatter. Instead, the vent emits great quantities of volcanic gas.
