Any idea if a meteorite hit Eureka? At about 1:30 am my wife and I saw a huge flash of light and heard a boom outside our house. I went running out and found nothing and no-one. Meteors aren’t supposed to flash when they hit but it is the only thing I can think of.
There was a tremendous boom/bang preceded by a bluish flash that I could see reflecting on the window a second or so just prior. It was on the east side of us. There was no way you could have slept through it. I'm not sure what time it was, but 12:42-12:45 sounds about right. Because of the flash I thought it was a transformer but tthe explosion was much louder and sounded more like a huge bottle bomb. Our windows didn't rattle but the dog was mighty freaked.
Just heard another one, accompanied by a flash, and this time we were able to spot a sizable cloud of smoke in the same direction. We’re reasonably certain it was smoke from the way it dissipated. We’re in Bayview, and the flash was due west. Could’ve been as far away as the north jetty, or just somewhere behind the mall. I’m guessing homemade mortars.
Colourless gas. Colourless liquid at extremely low temperatures or under very high pressure. Odour of rotten eggs at very low concentrations. Sickening sweet odour at 30-100 ppm. The ability to smell H2S can begin to dull at 50 ppm and can be completely lost. EXTREMELY FLAMMABLE GAS. Forms explosive mixtures with air over a wide concentration range. Very low ignition energy. Gas is heavier than air and may hug the ground. Distant ignition and flashback are possible. During a fire, irritating/toxic sulfur dioxide may be generated. Confined space hazard. Can accumulate in confined spaces, especially in low-lying, poorly ventilated areas, producing a fire/toxicity/explosion hazard. COMPRESSED GAS. Cylinders and closed containers may rupture violently if heated, releasing large amounts of flammable gas or may cause cylinder to rocket. May ignite in contact with some metal oxides and oxidants. VERY TOXIC. May be fatal if inhaled. EYE IRRITANT. Gas may be severely irritating to the eyes and respiratory tract. Causes lung injury-effects may be delayed. Inhalation of high concentrations may cause respiratory paralysis, irregular heartbeat, collapse and death. May cause nervous system effects. Liquefied escaping from cylinder can cause frostbite.
Fire Hazard Summary:
FLAMMABLE GAS. Burns with a pale blue flame. Form explosive mixtures with air over a wide range. Very low ignition energy. Ignites spontaneously at 260 deg C (500 deg F). Leaking gas will be initially colder and heavier than air, and may hug the ground and travel a considerable distance to a source of ignition and flash back to a leak. During a fire, irritating/toxic sulfur oxides (mainly sulfur dioxide) may be generated. Can accumulate in confined spaces, especially in low-lying, poorly ventilated areas, producing a fire/toxicity/explosion hazard. Compressed gas. Heat from fire can cause a rapid build-up of pressure inside cylinders, which may cause explosive rupture and a sudden release of large amounts of flammable gas or may cause cylinder to rocket.
