Israel military detects 6 blasts, each 11 seconds apart, before Beirut explosion
- ceejayoz 6y ago> “I do not believe that they are associated with the large explosion in Beirut,” Jerry Carter, director of IRIS data services, told Reuters. > “They could be from a seismic survey,” he added, referring to geologists carrying out airgun bursts for underwater mapping.
- tyingq 6y agoInteresting that Isreal is (maybe) capable of detecting far away fireworks bursts. I wonder how they filter out meaningless noise.
- thephyber 6y agoMy naïve guess is that it's used to assist in triangulating where incoming rockets / mortars are fired from. Edit: I read the article and it has nothing to do with the Iron Dome (unless it's military equipment posing as science equipment).
- tyingq 6y agoSure. I'm curious if they have some ML or other tech to weed out false positives.

- Zenst 6y agoI could speculate that an array of seismic or comparable detectors would be able to pick up direction and with filtering and processing, identify the type of source.

- frank2 6y ago>I wonder how they filter out meaningless noise If the meaningless noise is local, I would try employing multiple detectors separated widely.
- tyingq 6y agoI mean meaningless noise like mining, road building, seismic tests, fireworks displays, etc, versus actionable stuff.
- tatersolid 6y agoI would expect that the IDF has sonobuoys and hydrophone nets everywhere they can stick them in the area. Their neighbors have various large and small warships and have a history of using them via surprise tactics.

- ceejayoz 6y agoNext you're gonna tell me "News provided by Architects & Engineers for 9/11 Truth" on a paid PR site about an author who apparently hasn't published anything since 2002 (http://cem.uaf.edu/cee/people/leroy-hulsey.aspx http://cem.uaf.edu/cee/people/leroy-hulsey.aspx) is legit.
- maerF0x0 6y agoYou're not wrong. I was more trying to point out the conspiracy-like tone of the title. And coming from Israel ...
- fghorow 6y agoGeophysicist here. These 11 second periodic blasts are due to airguns from a Turkish seismic survey vessel that happened to be working in the region. N.B. they continued after the Beirut explosion. Here's a (long; thanks Zuck) link to a FB post from IRIS (the Incorporated Research Institutions for Seismology): https://www.facebook.com/IRISEarthquake/photos/a.361020589973/10158943990109974/?type=3&__xts__%5B0%5D=68.ARCQ2xtt4S6O1JJO8mz4ReWWCGs8NwcCVEH32leM7QYUR-Bm7TcXyFn0P7i6gkQLJC2Kg5-DSIXusJwqBq85SVzU2NYJomn6xm1bZniYFT4wuxihBPVQ-RU6xhJTIhO5LYfAZa0uUq7uPjriyW1_n8qj_uYB2ozR8Zcv4KFdSxyHbGxmqFGYLwdCsA0kwDe_fwigH1_FfqHjUKav-tNLGZL6VB9v1GGINF656LCAZFtXCPNGrEy3-2ErJkHs5y0lZ_Y6ijrd5RsOLTiDnOx-HUAemv7Cm_rG29dYqdMrzkls05q4YQw2j61z9H7XGjM200V6akNWB-0SvNWuLrCo&__tn__=-R https://www.facebook.com/IRISEarthquake/photos/a.36102058997...
- xref 6y ago> Hayoun assessed that the Beirut incident involved underground explosions. The 43-metre (140-foot) deep crater at the port could not have been left by the explosion of the amount of ammonium nitrate reported by Lebanese authorities, he said: “It would have been shallower, maximum 25 or 30 metres.” To make a claim about “maximum crater depth” seems like you’d need a lot of data about the ground composition below the storage area, and if the anfo was in a concrete silo that could amplify the blast by letting pressure build before failing etc
- dogma1138 6y agoIt’s not the Israeli military that claims that, it’s an Israeli seismologist that works for an oil company.
- stunt 6y agoThey should also investigate how the fire started in the warehouse. Some warehouse fire setting are just arson or have business motivations like insurance fraud. In many cases they have no idea what else is stored in the warehouse and things can go really wrong.
