The series of explosive eruptions in May 1924 followed the withdrawal of lava from lava lake in Halema‘uma‘u Crater that began in February and the ensuing collapse of its crater floor in late April. Scientists infer that the lava had drained to a depth below the water table at the summit, currently about 500 m (1,640 ft) below the floor of the caldera.

Eight persons, including newspaper and movie men observing the scene at Halema‘uma‘u, were caught in a rain of hot rocks from this explosion. The rocks emitted hissing sounds as hot gas, mainly steam, escaped from them. Park superintendent Thomas Boles was knocked down twice by this bombardment.

On May 11, Ruy Finch and W.O. Clark visited Halemaumau and found a rock fragment weighing about 180 kg (400 pounds) that had been thrown 60 meters (200 feet) from the rim of the crater.

Later scientists at the Observatory listed May 10 as the first day of the eruptive series. Between this date and May 27, they carefully recorded all explosions, ballistic falls, electric storms, and muddy rains as well as earthquakes felt and recorded on seismographs.

After the severe earthquake swarm in lower Puna subsided, seismic tremor became more pronounced at the summit of Kīlauea Volcano. The floor of the crater of Halemaumau continued to collapse.

On April 22, an observer at the Kapoho railroad quarry counted 238 felt earthquakes over a period of four hours. By Sunday, April 27, things had calmed considerably at Kapoho, although a dozen shocks were felt during the day and half a dozen more overnight.

These tracks were damaged by the vertical drop along the zone of cracks and faults that ran parallel to the east rift zone of Kīlauea Volcano. Witnesses reported that where the railroad entered the valley, the ties and rails were swinging like a suspension bridge for a distance of about 61 meters (200 feet).

By April 22, 1924, the incessant earthquakes caused many people to leave the district. When Hilo Tribune Herald reporter Jazz Belknap reached the Kapoho train station, he found a great crowd waiting for the autos that were hauling passengers out of the district.

Valley of Ten Thousand Smokes in Katmai National Park, circa 1922. Windy Creek is in the foreground. Following the June 6, 1912 eruption of Novarupta-Katmai, thousands of fumaroles filled the valley for many years. Buried snow fields, glacial streams, and precipitation were converted to steam by the heat trapped in the pyroclastic flow.
