    Blast from unexploded US bomb grounds flights at Japanese airport​

    An unexploded U.S. bomb from World War II that had been buried at a Japanese airport exploded Wednesday, causing a large crater in a taxiway and the cancellation of more than 80 flights, Japanese officials said.

    No one was hurt, and there were no aircraft nearby when the bomb exploded at Miyazaki Airport in southwestern Japan, Land and Transport Ministry officials said.

    An investigation by the Self-Defense Forces and police confirmed the explosion was caused by a 500-pound U.S. bomb and there was no further danger. Officials were determining what caused its sudden detonation.

    A video recorded by a nearby aviation school showed the blast spewing pieces of asphalt into the air like a fountain. Videos broadcast on Japanese television showed a crater in the taxiway reportedly about 7 meters (yards) in diameter and 1 meter (3 feet) deep.

    Chief Cabinet Secretary Yoshimasa Hayashi said more than 80 flights had been canceled at the airport as of midafternoon Wednesday.

    The airport said the taxiway damage was repaired overnight and flights resumed Thursday morning.

    Miyazaki Airport was built in 1943 as a former Imperial Japanese Navy flight training field from which some pilots took off on suicide attack missions.

    A number of unexploded bombs dropped by the U.S. military during World War II have been unearthed in the area, Defense Ministry officials said.

    Hundreds of tons of unexploded bombs from the war remain buried around Japan and are sometimes dug up at construction sites. (ABC News)

    High explosive සේරම වගේ plastic කාණ්ඩයට අයිති එ‍්වා. වෙඩි බෙහෙත් වගේ තදට pack කරල තිබ්බාම, වතුරෙන් බේරිලා තිබ්බාම පත්තු වෙන එ‍්වා නෙවෙයි. පොඩි කාලෙ අපි සෙල්ලම් කරපු plastic clay මතකනෙ. අන්න එ‍් වගේමයි. ගුලියක් අරගෙන කැමති හැඩේකට හදා ගන්න පුළුවන්. වෙනම contain කරන්න අවශ්‍ය නෑ.

    500 pound වගේ බෝම්බයක් හදද්දි එ‍්කෙ ප්‍රධාන අරමුණ blast pressure එකෙන් කරන විනාශයනෙ. ඉතින් shrapnel හෙවත් කොටස් කැඩිලා විසි වෙලා කරන හානිය එච්චර වැදගත් වෙන් නෑ. ඉතින් රාත්තල් 500 ම වෙන්න තනිකරම plastic explosive ගුලියක් තමයි ඕකෙ තියෙන්නෙ.

    Explosive එක අවුරුදු 80 නෙවෙයි 500 ක් විතර ගියත් සාමාන්‍ය තත්ත්ව යටතේ කිසිම වෙනසකට ලක් වෙන්නෙ නැහැ. මොකද එ‍්ක බොහොම stable රසායනික සංයෝග එකතුවක්. තෙත් වුණා කියලා, උෂ්ණත්වය වෙනස් වුණා කියලා වෙනසක් වෙන්න ඉඩක් නැහැ.

    අනික වෙඩි බෙහෙත් වගේ plastic explosive මොනව‍ත් රත් වුණාට, හයියෙන් යමක් වැදුණාට පුපුරන්න ඉඩක් නෑ. එ‍්වා පුපුරන්න ක්ෂණික shock එකක් එක්ක අධික තාපය combination එකක් තමයි ඕන. Blasting cap එකක් වගේ පාවිච්චි කරන්නෙ එ‍් නිසා.

    එ‍් හින්දා සාමාන්‍යයෙන් ඔය වගේ ලොකු බෝම්බයක් නිශ්ක්‍රීය කරද්දි වුණත් වැඩිපුරම බලන්නෙ අන්න එ‍් blasting mechanism එක අක්‍රීය කරන එක ගැන. Explosive එක කොහොමත් පට්ටම stable. එ‍්ක ගැන බය වෙන්න දෙයක් නෑ.

    කාලයක් යනකොට අක්‍රීය වෙනවා නම් වෙන්න තියෙන්නෙත් ඔය Blasting cap එක තමයි. එ‍් වගේම එ‍්ක අනවශ්‍ය විදිහට press වුණොත්, electric arc එකකට අහු වුණො‍ත් සක්‍රීය වෙන්න ඉඩක් තියෙනවා. මෙතනත් වෙලා තියෙන්නෙ එහෙම දෙයක් වෙන්න ඕන.
