The Pacific Northwest is host to more than the anticipated megathrust earthquake that will happen off the Cascadia coast in the future. That earthquake will be due to the stress building between the Juan de Fuca and North American plates as the oceanic Juan de Fuca plate dives deep beneath the Pacific Northwest.
However, there are also deep earthquakes within the subducting plate, and shallow earthquakes in the overlying continental crust. This is because of additional forces acting on the region besides subduction-zone processes.

Note the size of this Earthquake:

2018-12-11 02:26:30.6
8hr 07min ago 58.65S 26.44W 150 7.1 SOUTH SANDWICH ISLANDS REGION

from:
_Earthquakes today | Earthquake today | earthquake | earthquakes


Note the odd wave form appearing on this display, in the region of that earthquake, and seemingly originating out of the west coast of Africa.:

MIMIC-TPW "1"

from:
_MIMIC-TPW

I could not say if the two are related, however this is a strange phenomenon.

We are at the end of the year 2018, we left a survey to choose which earthquake impacted them more in this 2018, the deep quake #Fiji, the seismic sequence in #Lombok(#Indonesia), the seismic sequence in #Mayotte(#France ) o The earthquake of #BuenosAires(#Argentina).

After May postponed the Brexit vote in Parliament, the country is so determined to go back in time that even quakes occurred in the wrong order Also, hello Preston New Road seismicity! Where have you been for the last month? @seismo_steve

Use the map below to explore recent earthquake activity. This map shows the earthquake feed from the USGS for all earthquakes in the last 7 days within the SCSN reporting region. Expand the left sidebar to view the event listing; selecting an event will highlight its map location. Once selected, for further information, clicking an event ID (ex. ci38354200) link will take you to the USGS page for that event. Events are color-scaled by the time they occurred (red: within 1 hour; blue: within 1 day; yellow: within 7 days; grey: older) and size-scaled by their magnitude, as repressented in the legend below.

Please note that not all earthquake information displayed on this map may have been reviewed by a seismologist, and automated solutions are likely to be updated. The map updates every 5 minutes with the most recent earthquake data available, the same refresh rate as the USGS earthquake feed

That is bizarre. Anybody find any news item on that?
Had not found much except that, there was another explosion in November this year at pretty much the same place (+-KM) and, that Battle Mountain is also known by its fireworks.

--time went out, sorry for the duplication--
... there had been many earthqukes in Nevada, and over the Great Basin, see this map Nevada Seismological Lab, it does specify if it was an explosion or earthquake, I'm entretaining checking out if there were more :)

Russia’s Emergencies Ministry said that, according to preliminary information, there was no damage to Kamchatka peninsula following Thursday’s powerful quake, RIA news agency reported.

A major earthquake with a magnitude of 7.4 struck off Russia’s sparsely populated far east on Thursday, but officials said the threat of a tsunami had passed and no damage was reported.

The quake off Russia’s Kamchatka peninsula, which was initially measured at magnitude 7.8 by the United States Geological Survey (USGS), before being revised downwards, struck 82 km (50 miles) west of Nikolskoye at a depth of 9 km.

The Pacific Tsunami Warning Centre at first said hazardous tsunami waves from the earthquake were possible within 300 km of the epicenter along the coasts of Russia, but later said the threat of tsunami had passed.

Russian RIA and TASS news agencies, citing officials at the local Emergencies Ministry, also said there was no threat of a tsunami following the quake. No damage was reported, they said.
