Major solar flare triggers 3 strong earthquakes in Alaska (M6.3), Argentina (M6.3), Russia (M6.4)

Strange Sounds – December 1, 2020

Well, if you look back at data from the past two days, there is a clear correlation between the proton density sent from the sun and the occurrence of large earthquakes (M > 5.6), with a time shift of 1-2 day(s).

The biggest solar flare in more than 3 years occured on Nov. 29th, triggering widespread radio shortwave outages and hurling a huge CME in space.

Luckily, the small sunspot that erupted wasn’t facing Earth during its explosive event. But still, particles from the solar eruption may have triggered a series of 4 strong earthquakes that hit across the world within less than 12 hours between Nov. 30th and Dec. 1st.

M6.4 Russia – Nov. 30th, 22:54:34 (UTC)

The first earthquake of the series is a very deep M6.4 quake that hit 88 km SSE of Sovetskaya Gavan’, Russia.

The offshore quake epicenter was situated at a depth of 587km (364.7 miles) and no tsunami was created.

M6.3 Argentina – Nov. 30th, 22:54:59 (UTC)

Just 20 seconds after the first strong quake of the series, another big blast rattled 76 km WSW of San Antonio de los Cobres, Argentina.

Although very deep (147.8 km or 91.8 miles), the quake was reported by at least 16 people, most reporting very small shaking.

It is worthwhile to report that a M5.9 earthquake (so a big one too!) hit about the same region on Sunday, Nov. 29th at 1:40 p.m. local time – the same day than the solar eruption.

M6.3 Alaska – Dec. 1st, 16:22:40 (UTC)

Finally a M6.3 earthquake hit offshore, 38 km (23.6 miles) ESE of Nikolski, Alaska at a depth of 23 km (14.3 miles).

Eight reports of shaking have already been published on the USGS homepage.

Solar cycle 25: the Sun wakes up

Space Daily – October 30, 2020

The Sun has entered its 25th solar cycle and is about to wake up. For the last few years our star has been pretty sleepy, with few sunspots, bright flares or massive ejections of magnetized plasma emanating from its surface. This quiet period is known as the solar minimum, but things are starting to heat up again.

Experts on the Solar Cycle 25 Prediction Panel recently announced that the Sun has officially entered a new cycle, its 25th since we’ve had enough data to reliably recognize them. While we can expect space weather to get more exciting in the next few years, with peak sunspot activity expected in 2025, the panel came to the consensus that this next cycle will be very similar to the previous, both generally weaker than the average solar cycle.

“While small and medium-sized solar storms are more likely during peak solar activity,” explains Juha-Pekka Luntama, Head of ESA’s Space Weather Office, “it is important to remember that individual large solar events, huge flares and coronal mass ejections, can happen at any point, independent of where we are in the solar cycle or how strong the cycle becomes.”

If such solar storms impact Earth, they can create geomagnetic storms in our magnetosphere. While good news for aurora hunters, these storms can disrupt and even damage power grids on Earth and satellites in orbit, and the vital services they provide.
