vaivaigyanikon ke anusar bhumigat sathon men halachal hone se bhukanp ate hain. bhumi ki tektonik pleton ke khiskne se bhukanp ate hain. bhumi ke andar se vibhinn gaison v urja ki tarangon ke rup men bahar ane se in pleton men halachal hoti hai. praimri tarangon ki gati 6 se 7 milimitar prati sekand hoti hai aur sekandri tarangon ki gati 3.5 ki.mi. prati sekand hoti hai. ye tarangen chattanon ko idhr-udhar ya upr-niche khiska deti hain. bhukanp ki tivrata is bat par nirbhar karti hai ki uska kendra bhumi ki satah se kitna niche hai.
bhukanp vigyani jinhen sijmaelaejist kaha jata hai, bhumi ki halachal ko rikard karne ke lie sijmaegraf mashin ka prayog karte hain. unke anusar bhumi par prativarsh 10 lakh bhukanp ate hain. riktar paimane par bhukanp ki tivrata 2.5 tak hone par am admi ko bhukanp ka pata bhi nahin chalta lekin sijmaemitar bata deta hai. tivrata 3.5 hone par kuch hi log ise mahsus kar pate hain. tivrata 4.5 hone par mamuli nuksan ho sakte hain. tivrata 6 hone par kafi nuksan ho sakte hain. tivrata 7 ya isse adhik hone par bare paimane par tabahi hoti hai. bhukanp ka kendra prithvi par hone se kam tabahi dekhi gai hai. yahi kendra jab samudra ke niche hota hai to adhik tabahi hoti hai.
samudra se uthne vali tarangane jab tat ki or ati hain to sunami kahlati hain. in tarangon ki gati am bhukanp ki tarangon ki gati ka dasvan hissa hi hoti hai. islie sunami ki chetavni di ja sakti hai. bhukanp ke karan janne ke lie bhumi ki antrik sanrchna ko samjhna bhi jaruri hai. prithvi par ane vale bhukanp angreji men mantjiunanam aur chandrama par ane vale bhukanp davvdunanam kahlate hain. 1969 se 70 ke bich men chandrama ki satah par 5 jagah sijmaegraf steshan banae gae.
pratyek ne 600 se 3000 ke bich men munakvek ;davvdunanamaddh rikard kie jabki chandrama par koi tektonik plet ya samudra nahin hai. riktar paimane par inki tivrata 2 anki gai. is jankari ka prayog chandra ki antrik jankari ke lie kiya gaya. mangal par bhi sijmaegraf steshan lagaya gaya jahan par ek sal men sirf ek tarang hi rikard ki gai. bhuvaigyanik bhukanp ki bhavishyavani karne ka koi karagar upakaran abhi tak viksit nahin kar pae hain. bhukanp ke jyotishiya karan rhudhne ke lie ham mediniya jyotish ka sahara lete hain. mangal bhumi ka karak hai.
shani bhumi ke andar se niklne vali vastuon jaise vayu v gaison adi ka karak hai. rahu dharti kanpan karta hai aur tor for ka karak hai. in grahon ka apsi sanbandh banne par bare bhukanp ate hain. bhukanp ke kuch jyotishiya karan is prakar hain:
û mangal aur shani men purn drishti sanbandh ya sthan sanbandh.
û mangal aur shani ek dusre se kendra ya trikon men a jaen.
û shani svarashi men ho.
û mangal tula rashi men ho.
û mangal aur shani ka ashtam bhav se sanbandh ho.
û mangal shani ke nakshatra men arthat pushya, anuradha v uttarabhadrapad men ho.
û shani mangal ke nakshatra men arthat mrigshira, chitra v dhanishtha men ho.
û grahan se 3, 4, 5, 13, 16, 17, 28, 37, 48, 57, 71 v 78ven din bhukanp ate hain. bhukanp ke sthan ka nirdharan karne ke lie kurmachakra ka sahara liya jata hai. kurmachakra men kachue ki akriti banakar use 27 nakshatron men vargikrit kiya jata hai. aj ke vaigyanik lachai arthat lasvains chvepajapavadapadah ainjmsspjme ki sahayta se jis prakar se sthan ka nirdharan karte hain vahi karya hamare jyotishi kurmachakra dvara karte hain.
bhukanp se hani: chitra 7, 8, 9, 10 bhukanp se jan v mal ki hani hone ke sath-sath pine ke pani ki kami, svasthya sanbandhi samasyaen, vishva se sanpark kat jana adi kasht hote hain.
bhukanp ke prakritik lakshana:
û bhukanp se 6 se 78 din purva chintiyan lakhon ki sankhya men bhumi se nikal kar peron, chattanon v paharon par charhti hanai.
û kutte 2 ghante se 2 hafte pahle betrtib bhaunkte v bhagte hain.
û gahri kali bari chintiyan 6 ghante pahle sthan tyag kar ande lekar bhagti hain. û chuhe 12 se 36 ghante purva bilon se nikal kar bhagte hain.
û bandron ka utpat barh jata hai.
û gay rone v ranbhane lag jati hai. bhukanp ki punravritti: ek bhukanp se dusre bhukanp men antral 3,5,7,13,15,17,34 v 45 din ka hota hai. 26 janvri 2001 ko bhuj men pratah 08.46 par ae bhukanp ki kundli is prakar hai: bhuj ki kundli ka adhyayan karne par ham pate hain ki mangal ki athvin drishti shani par par rahi hai.
lagnesh shani chaturth bhav men vrish rashi men guru ke sath hai aur mangal navam bhav men tula rashi mane hai. ashtamesh budh lagn men shukra ke sath shani ki kunbh rashi men hai. rahu pancham bhav men mithun rashi men hai. kunbh lagn ke lie surya aur guru marak hain. marak guru ki drishti ashtam bhav par hai.
trikon men pap grah trikon ko pirit kar rahe hain. pratham bhav ke pirit hone se sthan ka svarup hi badal gaya. pancham bhav ke pirit hone se abadi ka nuksan hua. navam bhav ke pirit hone se unnati men badha ai. chaturth bhav par mangal ki drishti parne se avas ki samasya utpann hui. marak surya ke dvadash bhav men hone se kharchon ka bojh barha.
us samay ki kundli ke hisab se mangal ki mahadsha men shani ki antardasha chal rahi thi aur rahu ki pratyantar dasha men shani ki hi sukshm dasha thi. ab prashn yah uthta hai ki bhukanp ka prakop bhuj par hi sarvadhik kyon hua? dilli ya kisi anya sthan par kyon nahin? is prashn ka uttar dhundhne ke lie dilli aur bhuj ki us samay ki navansh kundliyon ka tulnatmak adhyayan karte hain. donon navansh kundliyon ka adhyayan karne par pate hain
ki bhuj men rashi ka pratham navansh aur dilli men rashi ka chaturth navansh tha. pratham navansh shubh nahin mana jata. bhuj ki navansh kundli men mangal ke ashtam bhav aur shani ke chaturth bhav men ane se hi bhukanp ka sarvadhik asar bhuj par hua. navansh kundli men surya uchch ka hone par bhi achche fal nahin de paya. kyonki saptam bhav men rahu ke sath hone se surya ko grahan sa lag gaya, isi karan parosi rajyon aur videshon se sahayta pahunchne men deri hui aur vyapak jan-hani hui.
marak guru bhi rog sthan men tha, dilli ki navansh kundli men surya aur rahu chaturth bhav men hain, jisse logon men bhay to vyapt hua, par jan-mal ka koi nuksan nahin hua. nauven bhav men chandra ho, to pancham bhav ke grah bhi sahayta pahunchate hain. shani svarashi men lagn men a gaya. is karan dilli men koi nuksan nahin hua. is prakar ham dekhte hain
ki mangal, shani aur ashtam bhav ka sanbandh bhukanp ka karan bana. bhuj ke bhukanp ke bad 2001 se 2005 ke bich men vishva men ae kuch bare bhukanp: in sabhi bare bhukanpon ka adhyayan karne par ham pate hain ki un tarikhon men mangal v shani ka drishti ya rashi sanbandh ban raha tha ya ve ek dusre se kendra ya trikon men the.
