10/21/18 Earthquake Trinidad
*5.2 mww* 11.25 Mi Depth
Earthquakes using mww or mwr scales usually mean the quake has substantial consequences seismically. As you can see, the USGS explanation of seismic scales is no better than no explanation, so the closest you can get to understanding the scales is to observe the global quake behavior surrounding these “special” quakes. I consider mww and mwr as alarm bells, signaling more earthquakes to come.
