The Riobamba earthquake strikes Ecuador.
1797 Riobamba earthquake
The 1797 Riobamba earthquake occurred at 12:30 UTC on 4 February. It devastated the city of Riobamba and many other cities in the Interandean valley, causing up to 40,000 casualties. It is estimated that seismic intensities in the epicentral area reached at least XI on the Mercalli scale, and that the earthquake had a magnitude of 8.3, the most powerful historical event known in Ecuador. The earthquake was studied by Alexander von Humboldt, when he visited the area in 1801/2.
Confederate States of America
In Montgomery, Alabama, delegates from six break-away U.S. states meet and form the Confederate States of America.
The Confederate States of America (also called the Confederacy, the Confederate States, C.S.A. and The South) was a government set up from 1861 to 1865 by eleven Southern slave states that had declared their secession from the United States. Secessionists argued that the United States Constitution was a compact among states, an agreement which each state could abandon without consultation. The U.S. government (The Union) rejected secession as illegal. Following a Confederate attack upon Fort Sumter, a federal fort in the Confederate state of South Carolina, the U.S. used military action to defeat the Confederacy. No foreign nation officially recognized the Confederate States of America as an independent country, but several did grant belligerent status.

in 1936Radium becomes the first radioactive element to be made synthetically.
On 4 February 1936, radium E (bismuth-210) became the first radioactive element to be made synthetically in the United States. Dr. John Jacob Livingood, at the radiation lab at University of California, Berkeley, was bombarding several elements with 5-MEV deuterons. He noted that irradiated bismuth emits fast electrons with a 5-day half-life, which matched the behavior of radium E.
