Summary:

• The USA had a third of the world covid deaths yesterday.  Japan has been leading the world for most of the past couple of months, and was #2 with 200 new deaths.  Germany #3 with 127 and Taiwan #4 with 54.
• Japan continued to have the most new cases with 41,584, with the USA and Taiwan #2 and #3, both in the range of 24,000.
• Who knows what is happening in China, which has reported 80,000 covid deaths since early December, which would thus mean around half of all deaths occurred in China.  However, most experts say around a million died these past two months, which would mean that China had about a hundred times more deaths than the entire world combined.
• But about the USA, this winter season has only had a mild bump compared to last year and the year before.  Hospitalization is a good indicator, for tests are performed and should be reliable.

Turning next to the subject of the day, the death total in the recent Turkey 7.8/7.5 earthquakes has exceeded 20,000.  The previous quake of this magnitude occurred in 1999, killing 17,127.  A 7.8 earthquake in 1939 saw 32,700 killed.  The country is in a seismically active area where the Eurasian, African and Arabian plates are colliding.  The orange ones are of magnitude 7 and higher.

Here is a historic list of relatively recent earthquake casualties.

• 1905  India  (Kangra)            7.8    20,000
• 1908  Italy (Messina)            7.2    82,000
• 1915  Italy (Avezzano)          6.9    32,610
• 1920  China (Hiyuan)           8.6  235,502
• 1923  Japan (Great Kanto)    7.9  142,807
• 1927  China (Gulang)           7.9    80,000
• 1935  Pakistan (Auetta)        8.1    60,000
• 1939  Chile (Chillan)            7.7    28,000
• 1939  Turkey (Erzincan)       7.8    33,000
• 1970  Peru (Ancash)             7.9    70,000
• 1976  Guatemala                  7.5     23,000
• 1976  China  (Tangshan)      7.6   655,237
• 1988  Armenia                      6.7    25,000
• 1990  Iran                              7.4    45,000
• 2001  India (Gujarat)            7.6    20,023
• 2003  Iran (Bam)                   6.6    31,000
• 2004  Indonesia (Sumatra)    9.1  297,200
• 2005  Pakistan (Kashmir)     7.6    87,351
• 2008  Chiba (Sichuan)          7.6    88,287
• 2010  Haiti                            7.0  316,000
• 2023  Turkey (+Syria)          7.8    20,000+

Here are the deadliest earthquakes in history:

• #1    1556  Sanxi, China  8.0  830,000
• #2    2010  Port-au-Prince, Haiti  7.0  316,000
• #3      115  Antakya, Turkey  7.5  260,000
• #4      525  Antakya, Turkey  ?  250,000
• #5    1976  Tangshan, China  7.8  242,769
• #6    1139  Gyzndzha, Azerbaijan  ?  230,000
• #7    2004  Sumatra, Indonesia  9.1  227,899
• #8      856  Damghan, Iran  8.3  200,000
• #9      893  Dvin, Armenia  ?  150,000
• #10  1923  Tokyo, Japan  ?  142,807 

Note the differences from the above list by Wikipedia and the one below by Newsweek.   For example, a death difference of 655,327 and 242,769 for Tangsan, China.  Both numbers can be found in references, and this earthquake only occurred in 1976.  Something about reliable data from China.  Also, why don't the deaths increase with higher magnitude?

• Location near populations centers.
• Depth of epicenter.
• Type of infrastructure.

And, no matter what people say and in what they believe, there is yet no sure way to predict earthquakes.  That from the USGS.  From Wikipedia, some statistical data might provide a clue, as for example clustering of smaller earthquakes.  The thinking is that maybe 5% of serious earthquakes have followed this sequence.

Then the question is about any value to earthquake warnings.  What would be the economic and societal cost to scaring a population base and be a lot more wrong than right. There is that cost-benefit ratio of earthquake prediction.

Then there are precursors, running from aeronomy to zoology.

• Before an earthquake, there are pressure waves and foreshocks not noticed by humans, but detected by a variety of animals.  Studies have covered 130 species over thousands of years, mostly in China and Japan.  The general conclusion is that these behaviors were not necessarily predictive.

• 
  These waves can be measured by seismometers and other instruments.  Something called seismic waves have been confirmed to predict certain earthquakes.  It's possible that this method can be developed to work.

• 
  Radon gas released by seismic stress can be measured and used as a prediction tool.  However, this phenomenon does not always occur.
• There are electromagnetic anomalies like ultra low frequency magnetic changes, but the field has generally discredited this technique.

• 
  Maybe the most touted (and criticized) claim is the VAN method from the University of Athens.  The researchers measured geoelectric voltages, providing from 6 to 115 hours of warning time.  Most reviewers found the method to be flawed.  A 2020 report indicated that the VAN method suffered from an abundance of false positives and was therefore not usable as a prediction protocol.
• Perhaps the most celebrated prediction occurred in Corralitos, California a month prior to the 1989 Loma Prieta earthquake which occurred around 5 miles away.  I wrote about my experience with this event several times.  Just 3 hours before the quake, a seismo-electromagnetic device  soared to about 30 times greater than normal.  Certainly, there must have been a reason, but subsequent monitoring throughout California did not repeat anything like this, so the Corralitos anomaly was cast aside as a sensor-system malfunction, or unrelated magnetic disturbance.

• 
  Satellites measurements, ionospheric disturbances and a range of space related options have been looked at, but nothing dependable has developed.
• There are examples of predictive successes for several major earthquakes, but nothing has subsequently been universally acclaimed.

There was optimism in the 1970's leading to decades of disappointments.  Most experts today say that earthquake prediction is not intrinsically impossible.  Time, luck and such will tell.

I'll end with some photos from Gretchan Gould about Marjorie Taylor Green regarding the Chinese balloon and the heckling of Biden at his State of the Union presentation.
