Fire department calls Hawaii lab explosion an accident

U.S. News

A visiting researcher who lost an arm last month in a laboratory explosion at the University of Hawaii told fire investigators the blast occurred after she turned off a digital pressure gauge she was using to check the pressure in a gas cylinder. A report released by the Honolulu Fire Department on Monday said the researcher told investigators she didn't hear gas leaking before the explosion. Photos in the report showed torn pieces of a metal gas cylinder sitting on a floor strewn with debris. Compressed hydrogen, carbon dioxide and oxygen detonated inside an air tank in the laboratory, fire investigators said in their report. Fire investigators concluded the blast was an accident.


Investigators: Lab explosion caused by electrostatic charge

U.S. News

Michael Bruno, vice chancellor for research at the University of Hawaii at Manoa, talks to reporters Friday, July 1, 2016, in Honolulu. A laboratory explosion at the University of Hawaii that resulted in a researcher losing her arm was likely caused by static electricity, according to an independent investigation. The University of California Center for Laboratory Safety, which handled the investigation, released its results Friday.


Kilauea summit blows ash aloft anew as more lava flows into Pacific

The Japan Times

HONOLULU – A small explosion at the summit of Hawaii's erupting Kilauea Volcano on Sunday sent ash spewing into the air, creating a driving hazard for roads on parts of the Big Island, the U.S. Geological Survey said. Lava fountains from a fissure in the volcano reached as high as 180 feet (55 meters) from Saturday night into Sunday, pushing flows of molten rock into the ocean, it said. "Seismic activity at the crater continues with gas explosions and ash eruptions under 10,000 feet (3,050 meters). While the eruption is never predictable, conditions appear stable for the moment," Richard Rapoza, a spokesman for Hawaii Emergency Management Agency, said in an email. The eruption, which entered its 39th day on Sunday, stands as the most destructive in the United States since at least the violent 1980 eruption of Mount St. Helens in Washington state that reduced hundreds of square miles (km) to wasteland and killed nearly 60 people, according to geologist Scott Rowland, a volcanologist at the University of Hawaii at Manoa.


Hawai'i's Kilauea Eruption Did Not Rain Gemstones From The Sky

Forbes - Tech

Since the beginning of May 2018, the Kilauea volcano on Hawai'i is erupting. First a cloud of fragmented older lava, volcanic ash and vapor rose from the Pu'u'O'o crater on the summit, magma then migrated to the flanks, opening a series of fissures from where now lava is pouring out. Around five weeks into the eruption, some residents of the town of Kalapana reported small, green crystals to be found on the ground, soon speculating that the crystals rained out from the eruption column or the lava fountains of Kilauea. The green crystals are olivine, a very common magnesium-iron-silicate mineral to be found in magmatic rocks. Olivine crystals of high quality are used also in jewelry.

The Second International Workshop on User Modeling was held March 30- April 1, 1990 in Honolulu, Hawaii. The general chairperson was Dr. Wolfgang Wahlster of the University of Saarbrucken; the program and local arrangements chairperson was Dr. David Chin of the University of Hawaii at Manoa. The workshop was sponsored by AAAI and the University of Hawaii, with AAAI providing eight travel stipends for students.
