While there are several charts you might consider for Venezuela, Campion’s amazing “The Book of World Horoscopes” starts its charts for the country with its Proclamation of Independence on July 5, 1811 at 4:27 pm. This provides an Ascendant of 12 Libra 51 and an MC of 11 Cancer 44 for the capital: Caracas at 10 N 30’ 22” and 66 W 54’ 52”
For Earthquakes: Aleppo #13128, Richter #3338, Shaanxi #2263 and Tangshan #2778.
You might also check the TNP Admetus and the asteroids Admete and Admetos as they refer to “deep in the earth” or land.
You can try using Melpomene for the theme of a tragedy. Other points will also be strong.
