The spatial distribution of superbolides from the CNEOS database with impact energy \u22651 kt was found to be uniform, with a global frequency estimate of 5.73 \u00d7 10\u22129 events\/km2\/year. However, this conclusion does not hold when considering the entire GLM-Bolides dataset associated with confirmed events. For a country the size of Brazil, the expected frequency of events with impact energy \u22651 kt is one every 19\u00e2\u0080\u009320 years. The distribution of superbolide energy in the CNEOS database, modeled using the Generalized Pareto Distribution, estimates an average recurrence period of one \u2265440 kt event every 80 years and one \u226515, 000 kt event every 1,100 years for Chelyabinsk- and Tunguska-like impacts, respectively. A significant negative correlation was found between altitude and the known total weight (KTW) of the meteorites associated with the CNEOS superbolides, suggesting that higher altitudes favor greater fragment dispersion. A comparison of the velocity and altitude distributions between BRAMON meteors and CNEOS superbolides indicates that extreme events such as Tunguska probably do not have a cometary origin.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Alberto S Betzler Monthly Notices of the Royal Astronomical Society, staf673Published: 24 April 2025 LINK + PDF (OPEN ACCESS) &#8220;This study analyzes the positional and physical data of meteors and superbolides observed by the ground-based&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[96,97],"tags":[118,5963,4613,4173,902],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/38161"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=38161"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/38161\/revisions"}],"predecessor-version":[{"id":38162,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/38161\/revisions\/38162"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=38161"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=38161"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=38161"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
