According to a real-time map of earthquakes, created by Mapbox, using data collected from the USGS earthquake data feed, there have been 9,651 tremors detected in the last 30 days, 1,740 of them occurring in the last week and 176 in the last day. (Note these numbers change as each new tremor is recorded)

A screen shot of the map shows why all eyes should be on the "Ring of Fire," which is "a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. It has 452 volcanoes (more than 75% of the world's active and dormant volcanoes)," according to Wikipedia.

With the recent FEMA Drill called Cascadia Rising, which practiced a simulated field response operation within their jurisdictions and with neighboring communities, state EOCs, FEMA, and major military commands to a scenario of a 9.0 magnitude earthquake along the Cascadia Subduction Zone (CSZ) and the resulting tsunami, it once again highlighted the fact that the U.S. government is preparing for what scientists and researchers have warned is long overdue.... the big one.

The Cascadia Rising 2016 page states "Recent subduction zone earthquakes around the world underscore the catastrophic impacts we will face when the next CSZ earthquake and tsunami occurs in our region," as they highlight the 2004 Indonesia event (9.1 mag EQ) with 228,000 fatalities, the 2010 EQ in Chile (8.8 mag) causing 500 fatalities and the 2011 Japan 9.0 EQ which caused 18,000 fatalities, not counting the global damage still being done from the subsequent Fukushima nuclear plant meltdowns.

The Cascadia Subduction Zone is not the only area of concern though as a dire warning came out in early May, reported on by the LA Times, with a headline of "San Andreas fault 'locked, loaded and ready to roll' with big earthquake, expert says."

The San Andreas fault is one of California’s most dangerous, and is the state’s longest fault. Yet for Southern California, the last big earthquake to strike the southern San Andreas was in 1857, when a magnitude 7.9 earthquake ruptured an astonishing 185 miles between Monterey County and the San Gabriel Mountains near Los Angeles.

It has been quiet since then — too quiet, said Thomas Jordan, director of the Southern California Earthquake Center.

"The springs on the San Andreas system have been wound very, very tight. And the southern San Andreas fault, in particular, looks like it’s locked, loaded and ready to go," Jordan said in the opening keynote talk.

The key quote from that article states "Here’s the problem: Scientists have observed that based on the movement of tectonic plates, with the Pacific plate moving northwest of the North American plate, earthquakes should be relieving about 16 feet of accumulated plate movement every 100 years. Yet the San Andreas has not relieved stress that has been building up for more than a century." Two days ago it was reported that large-scale motion detected near San Andreas Fault system.

Now we see a prediction offered by scientists from the University of Hawaii at Mānoa of a "nine percent chance a magnitude 9 or larger earthquake will strike the Aleutian Islands in the next 50 years," reported by Extinction Protocol.

What does Cascadia, Aleutian and San Andreas Fault have in common? They are all connected to the Ring of Fire, as shown by the USGS map shown below, obtained from Google images.
