EXPLOSIVE ERUPTIONS OF 1924 IS THE VOLCANO WATCH topic this week; the column written by USGS Hawaiian Volcano Observatory scientists and affiliates:
For nearly two decades prior to the explosive eruptions in 1924, Halemaʻumaʻu hosted a large lava lake. In February 1924, this lava lake drained over the course of 2 days, leaving behind an incandescent crater that was around 380 ft deep by 1,700 ft wide (115 m deep by 520 m wide). Halemaʻumaʻu remained an empty crater for the next 2 months.
April 1924 saw the summit of Kīlauea hit with an earthquake swarm that migrated down the East Rift Zone. Residents of Kapoho in the lower East Rift Zone felt more than 200 earthquakes on April 22–23, which resulted in an approximately 4-mile-long by 1-mile-wide (6.5 by 1.6 km) tract of land cracking and subsiding. This included the area near the eastern point of the Island of Hawaiʻi dropping by about 14 ft (4m) and the ocean covering nearly a half mile (1 km) of previously dry land. Despite the shaking and subsidence in the lower East Rift Zone, associated with lava draining from the summit lava lake, no eruption occurred from the rift zone.

Explosions of ash, lapilli, and blocks continued to be ejected from the crater. The largest of these explosions occurred on May 18 with lightning-charged ash going up higher than 4 miles (6.5 km), as well as spreading across the crater floor. Several people were near the crater rim when this explosion occurred. Unfortunately, a resident of Pāhala was hit by a block and died that night at the hospital in Hilo. This was the only fatality during these explosive eruptions.
Scientists originally proposed that the lava lake draining exposed cracks in the crater floor that allowed groundwater to enter the system. This groundwater may have flashed to steam and resulted in the many explosions over the 16 days in May 1924. However, new research being undertaken by the Hawaiian Volcano Observatory could reveal other explanations for these explosive events. This research will help us to better understand these explosive bursts that occurred nearly a century ago and compare them with the more recent explosions from the summit of Kīlauea in 2018.

Kīlauea is not erupting. Its USGS Volcano Alert level is ADVISORY. Webcams show no signs of active
Mauna Loa is not erupting. Its USGS Volcano Alert Level is at NORMAL.
Webcams show no signs of activity on Mauna Loa. Seismicity remains low. Summit ground deformation rates show inflation above background levels, but this is not uncommon following eruptions. SO2 emission rates are at background levels.
There were five earthquakes above magnitude 3 and with 3 or more felt reports in the Hawaiian Islands during the the week ending May 10: a M3.5 earthquake 9 km (6 mi) ESE of Pāhala at 32 km (19 mi) depth on May 10 at 4:56 a.m. HST, a M3.8 earthquake 11 km (6 mi) ENE of Pāhala at 32 km (19 mi) depth on May 7 at 11:58 p.m. HST, a M3.3 earthquake 0 km (0 mi) NE of Pāhala at 39 km (24 mi) depth on May 7 at 7:35 a.m. HST, a M3.0 earthquake 35 km (21 mi) ENE of Waimānalo Beach at 8 km (5 mi) depth on May 5 at 4:26 p.m. HST, and a M3.7 earthquake 12 km (7 mi) SSE of Fern Forest at 5 km (3 mi) depth on May 4 at 1:05 p.m. HST.

THE RESIDENT OF PĀHALA WHO DIED IN THE 1924 VOLCANIC ERUPTION of Kīlauea was Truman T. Taylor, bookkeeper for Pāhala Sugar Plantation, according to the Hawaiian language newspaper of the time Ka Nupepa Kuokoa. Two soldiers also died in the blast and were never found, according to a translation of the the May 22, 1924 front page story in Kuokoa:
Amongst the visitors on this past Sunday was one who met with tragedy, after breaking both his legs and being burned by the hot ash from the lava, that being Truman T. Taylor, the bookkeeper of Pahala Sugar Plantation.
Two soldiers disappeared on that same day after the lava exploded violently, and their whereabouts are not known; a great number of soldiers were sent under the leadership of Captain Charles H. Perkins to search of them.
It is said that Truman A. Taylor was around 1,800 feet from the crater, and even at that distance, large rocks were thrown into the sky from the crater and they fell on this side and that side of the pit.
Someone heard a voice calling saw Mr. Taylor, and when they went to save him, it was seen that he broke both legs, and his body was scorched by the hot ash of the lava that was thrown up above.
The victim was given medical treatment at the soldier camp at Kilauea and from there was quickly transported to the hospital in Hilo; there he died.

for 2021 and 2022. Photo by Myra Sumida
Makuakane is 73 years young and was nominated by Hawai’i County Nutrition program for the Hawai’i County Office of Aging 2022 Outstanding Older American Award. The awards bio describes her as a Kaʻū girl who grew up in Nā'ālehu. "Lucy is helpful, kind, talented, and is a great example of someone living their senior years to the fullest. Her support of both the Nā'ālehu and Pāhala Senior programs makes her outstanding in the eyes of her friends in both communities. She currently serves on the executive boards of both the Nā'ālehu Senior Club (President) and the Pāhala Senior Club (Advisor). She is a willing

She said, “I’m not much of a talker; I’m more of a doer!” She is an accomplished tennis athlete playing in the Nationals seven times and placing twice since joining the USTA Senior Tennis League.

"The recent indictment of Rep. George Santos and the ethics abuses surrounding Clarence Thomas are exactly why trust in public officials remains at an all time low. Corruption in government is not new, but that doesn't mean we have to turn a blind eye either. It's a betrayal of public trust.
"I stand with the growing number of Democrats and Republicans calling on The Speaker to expel George Santos. And I support the efforts in Congress to create a binding code of ethics for The Supreme Court.
"Since being elected I've demanded reforms from the bottom to the top, from rules regulating our elections, to increased transparency in government, and, once elected, holding those in power accountable for their actions. No one is above the law and there shouldn't be double standards!
"It won't happen overnight, but there are bold steps we can take as elected officials to start to root out corruption."
During the closure, County of Hawai'i encourages residents to use the nearest available recycling and transfer stations at Ocean View (92-9017 Māmalahoa Highway) and Pāhala (96-1250 Old Māmalahoa Highway). Both transfer stations are open Sundays, Tuesdays, and Fridays from 6 a.m. to 6 p.m.
