It is true that the conjunction of Saturn and Mars in a violent sign (Aries, Taurus, Scorpio and Aquarius) causes all sorts of natural disasters like earth quakes, cyclones, volcanic eruptions, typhoons and storms. I will now explain this by examples as under: -
(a) 26.8.1883. Netherlands rocked; eruption of Krekatoas; violent explosions destroyed two-thirds of the Island; 36000 people died; many buildings collapsed. Saturn and Mars were then conjoined in Taurus, a violent sign. Venus and Mercury conjoined in Cancer.
(b) 28.10.1891. Mino and Owain Provinces near Nagoya, Japan severely rocked; 7500 people killed; 2 lac houses destroyed; many rendered homeless. Saturn and Mars at that time conjoined in Virgo. Venus and Mercury also conjoined in Libra.
(c) 12.6.1897. Assam severely jolted; destroyed many buildings; thousands of people killed. At that time Mars was in Leo and Saturn in Scorpio, both aspecting each other.
(d) 18.4.1906. San Francisco severely jerked; destroyed hundreds of buildings thousands lost their lives. Saturn was in Aquarius and Mars in Aries. Both were placed in violent signs. Saturn had 3rd aspect on Mars. The Sun and Moon conjoined with Saturn in Aquarius.
(e) 15.12.1916. Kemsu, China severely rocked; great landslides occurred killing lacs of people; many buildings were shaken into pieces; lacs of trees uprooted. Saturn was then in Cancer and Mars in Sagittarius. Mars had 8th aspect over Saturn. Ketu and Saturn conjoined in Cancer.
(f) 1.9.1923. Tokyo was severely rocked; many buildings destroyed; lacs of people killed; Rahu and Mars then conjoined in Leo - a fiery sign. Saturn and Rahu are identical planets. So this conjunction in a fiery sign Leo gave the worst natural disaster. From the above, you will find that the conjunction of Saturn and Mars in a violent sign causes all sorts of natural calamities.
5. Whether Astama Sani i.e. Saturn in the 8th is at all harmful
Astama Sani i.e. Saturn in the 8th if conjoins with Mars or gets aspects from Mars causes all sorts of violent deaths. Conjunction of Saturn and Mars in violent signs (Aries, Taurus, Scorpio and Aquarius) is a very dangerous affliction which generally causes violent accidental deaths. I will now explain this phenomenon by example horoscopes: -
(a) Death by assassination
Birth-chart: Taurus-Mars and Rahu; Scorpio-Ketu; Sagittarius-Saturn; Capricorn-Sun and Mercury; Aquarius-Venus and the Moon; Aries-Jupiter (Born on 15.1.1929 at 1 p.m.)
This is the horoscope of the American Negro leader of non-violence Dr Martin Luther King who won Nobel peace prize in 1964. He was assassinated on 4.4.1968. Saturn is placed in the 8th aspected by Mars. Conjunction of Mars and Rahu is placed in a violent sign Taurus and in the lagna. These two afflictions caused his violent death. Thus astama Sani i.e. Saturn in the 8th proved to be very evil.
(b) Death by plane crash.
Birth-chart: Aries-Ascendant, Mars; Gemini-Ketu; Leo-Jupiter; Virgo-the Moon; Scorpio-Saturn; Capricorn-the Sun, Mercury and Rahu; Aquarius-Venus (Born on 23.1.1897 at 12 p.m.)
This horoscope is of Netaji Subhas Chandra Bose who died in a plane crash on 18.8.1945. Saturn is placed in the 8th in a violent sign Scorpio aspected by Mars by its 8th aspect. This single affliction caused his violent death.
(c) Death by bomb explosion.
Birth-chart: Sagittarius-Ascendant; Capricorn-Rahu; Aries-Jupiter; Cancer-Ketu and Saturn; Leo-the Moon; Virgo-the Sun and Mercury; Libra-Mars. (Born on 25.9.1916 at 12.30 p.m.)
This is the horoscope of Pandit Din Dayal Upadhyay who died of bomb explosion. Saturn is posited in the 8th along with Ketu. Astama Sani proved to be very dangerous in his life.
(d) Death by execution.
Birth-chart: Aquarius-Ascendant, Jupiter; Aries-the Moon; Taurus-Rahu; Virgo-Saturn and Mars; Scorpio-the Sun, Venus, Ketu and Mercury. (Born on 15.11.1891 at 12.15 noon)
This is the horoscope of German Field Marshall Erwin Rommell. He tried to assassinate Hitler in a coup-de-etat but failed. He was the executed by Military Court-Marshal. Saturn is placed in the 8th along with Mars aspected by Rahu. Thus astama Sani proved to be very evil in his life.
