What does the Richter scale determine?

1989 was the year of the Loma Prieta earthquake in Northern California at over 7 on the scale. It caused massive destruction and many deaths mainly in San Francisco. The epicenter was in Santa Cruz where I lived at the time

Player #120374466, my family and I moved from San Francisco to Sacramento in 1988. So we avoided the earthquake fortunately. But we knew many people who were affected. I still remember watching the World Series when things started shaking. The Bay Bridge fell. Freeways collapsed. One of the worst earthquakes ever.

I love on the island of Crete, and 5 years ago, after living here already for 8 years, I have felt the first 7richter quake, destroyed villages and even cities! It was a nightmare! Since that day we have over 200quakes on a daily base! Now, in Santorini like a month ago, another 7 richter struck and “woke” up the volcano! Idk what’s going on here, but them quakes ain’t normal no more! They started and ended when they start build an airport in a village no one actually lives! Now in Santorini it started with the start of building a new metro line! They shouldn’t drill that deep under ground! Many lives lost. Another tragedy

Another severe quake was in early 1990s . I believe it was called the Northridge quake caused by an unknown fault.

Lol why did a lot of people pick number of push-ups you can do
