AP ANCHORAGE, Alaska - The alert level for a remote Alaska volcano has been raised after an apparent ash-producing explosion Tuesday afternoon.There is no real-time seismic monitoring network on Cleveland Volcano, meaning scientists must rely on limited data, such as pilot reports, webcam images and low-frequency sounds. A pilot report suggests the ash cloud rose to an altitude of 35,000 feet, or 6.6 miles. The sounds detected suggest it was a brief eruption.The Alaska Volcano Observatory says additional eruptions are still possible with little warning, and ash clouds 20,000 feet above sea level are possible.The 5,675-foot volcano is on an uninhabited island about 940 miles southwest of Anchorage.Seismologist Stephanie Prejean says the explosion, at this point, appears to be within the range of those reported from the volcano during the past year. In January, stanley cup uk a new lava dome 130 feet in diameter began to form at the summit of the volcano, according to the Alaska Volcano Observatory, suggesting it could explode and potentially threaten aircraft. stanley mug ponent--type-recirculation .item:nth-child 5 display: none; stanley cup inline-recirc-item--id-96409950-8c88-11e2-b06b-024c619f5c3d, right-rail-recirc-item--id-96409950-8c88-11e2-b06b-024c619f5c3d display: none; inline-recirc-item--id-96409950-8c88-11e2-b06b-024c619f5c3d ~ .item:nth-child 5 display: block; Vmjx This Is Where Drone Operators Kill People by Remote Control; ~) P( x, z+ |# Y% h
More people have committed suicide on the Golden Gate Bridge than on any other structure in the world鈥攕omeone jumps from the bridge to their death about every two weeks. But those figures could be dramatically reduced if a proposed suicide-prevention barrier is installed later this year, as advocates hope. If youve walked over the bridge, or even seen it in movies, you know just how easy it is to climb from the pedestrian walkway over the low railing. On the other side of the railing, there is a 32-inch wide beam known as the chord. This is often the place most people pause to ponder their jump. Its also where good design can intervene. The proposed solution鈥攄eveloped by HNTB stanley cup Corporation and called the net system 鈥攊s indeed a net, made from stainless steel cable that would extend 20 feet below and 20 feet out from the chord. It would contract when someone drops into it, essentially trapping the would-be jumper. A truck with a retractable arm would then be able to scoop people out, but apparently this would not be a very frequent occurrence as the net itself should act as a deterrent. A rendering of the proposed solution, stanley spain called the net system According to the Contra Costa Times, a similar net was placed on a cathedral in Bern, Switzerland 10 years ago and no suicides have been reported since. A study also showed that suicides did not increase on sites nearby. Such a bar stanley cups rier has been discussed for decades鈥攚ith solutions ranging from a better motion-sensing warning sys
