Natural Disasters 
We waited omnipotently for the occurrence of The Berg Timer's strongest day of 1992 on October 18, a "21" strength day. We knew when, but where? It all started in Egypt on October 12. A powerful 5.9 quake struck Cairo killing 370. Then, on October 17 a 6.6 quake struck Colombia, South America. Then another quake hit Colombia, a 7.2 quake on October 18. California finally felt the push with a 4.7 quake and seven aftershocks on October 21. Then on October 24 a 6.7 quake hit Soviet Georgia. These quakes occurred between 6 days before to 6 days after BT's strongest day of 1992, just as I've forecasted.

Earthquakes
Daily Earthquakes 
Quakes are most probable during the low BT periods just before and just after strong BT days (BT inverted in chart for easy viewing).
Below are compared world quakes > 5.9 and The Berg Timer for late 2005.
Below are compared all 2002 world quakes 5.5 or stronger and The Berg Timer.
These events met at least one of the following criteria: moderate damage (approximately $1 million or more), 10 or more deaths, magnitude 7.5 or greater, or Modified Mercalli intensity X or greater. Note the clustering around the strongest BT days.
The Great Cascadia Megathrust Earthquake of 1700
This immense quake was featured on the Discovery Channel on April 17, 2005. It occurred just before a very strong "15" strength BT day.

This great earthquake occurred about 9 pm on the night of January 26 in the year 1700. This was almost 100 years before the first European explorers made contact with native peoples on the west coast. The time and date of the earthquake are known because the large tsunami, or tidal wave, generated by the earthquake swept across the Pacific Ocean and did considerable damage at several places along the east coast of Japan. Japan has a written history dating to that time, and the size of the tsunami and its arrival time were well recorded. Using this, and other historical data, scientists were able to calculate the time of occurrence, location, and size of the generating earthquake. This was one of the world's great earthquakes with a magnitude estimated at 9. Oral traditions of the native peoples of Vancouver Island suggest the tsunami destroyed a village at Pachena Bay on the west coast of Vancouver Island, and that the shaking damaged houses in the Cowichan Lake region of south central Vancouver Island.
This earthquake occurred on the Cascadia Fault, the boundary between the North American and Juan de Fuca plates. This type of large earthquake is now known as a megathrust earthquake.
Morocco Quake of Feb 24, 2004
The devastating Morocco earthquake on February 24 killed 600 and left thousands homeless. It occurred within one week of very strong daily BT. The below forecast was publicly provided to newsgroups two months prior to the earthquake and was also published on this website. Again, strong quakes can be expected within one week on either side of very strong daily BT.
Central California and Iran Quakes of December 2003 
The Central California and Bam Iran quakes struck, as usual, during a low BT period just before a very strong BT day. Two persons died in the California quake and 26,271 died in the Iran quake.
Below are shown the 2000 world quakes >5.9 compared to BT. Note the strong clustering of quakes between the two strong BT periods.
The strongest individual quake was an 8.0 which hit Indonesia on June 4, killing 103 with $6 million in damage. The strongest quake lines are when two or more quakes occurred on the same day. The magnitudes of the quakes were totaled for each day.
California Quakes 
California quakes are most likely during the week preceeding a Berg Timer value of seven "7" or greater as the planets are moving toward conjunction. Up to 400% more quakes occurred in the eight days preceeding BT = 7 than at any other time. The fewest earthquakes occurred when BT = 7 or more.
Below are compared daily earthquakes in California >3.9 and the daily Berg Timer for 1997 through 2000 upon which some of the above summary is based. Most quakes occur just before strong BT days.
The correlation is quite consistent over all years studied. Earthquakes occur when BT is very low just before strong BT. The strongest quakes occur when BT is very low for a sustained period just prior to strong BT.
The strongest quake period above was mid-October 1999 when the Bullion Mountains (Hector Mine) 7.4 earthquake occurred. There was a prolonged period of low BT immediately followed by very strong BT. You should be aware of these periods if you live in a California.
Other California Quakes and International Quakes 
The three quakes shown above in red were discussed in my November 1992 issue of WEF. Below is the excerpt:
"We waited omnipotently for the occurrence of The Berg Timer's strongest day of 1992 on October 18, a "21" strength day. We knew when, but where? It all started in Egypt on October 12. A powerful 5.9 quake struck Cairo killing 370. Then, on October 17 a 6.6 quake struck Colombia, South America. Then another quake hit Colombia, a 7.2 quake on October 18. California finally felt the push with a 4.7 quake and seven aftershocks on October 21. Then on October 24 a 6.7 quake hit Soviet Georgia. These quakes occurred between 6 days before to 6 days after BT's strongest day of 1992, just as I've forecasted."

The Great 1906 San Francisco Earthquake 
Below are compared the quakes occurring in California in 1906 and The Berg Timer.
Strong earthquakes are most probable just before and after strong BT days. The San Francisco quake struck on April 18, 1906, just before one of these strong BT periods. The 7.8 strength quake killed 3,000 with $524 million in property damage.
The Northridge Earthquake of 1994 
Below are compared California quakes >3.9 and The Berg Timer in early 1994.
The 6.7 Northridge quake occurred on January 17, 1994. Fifty seven died with more than 9,000 injured and $40 million in property damage. The quake occurred during a sustained period of very low BT followed by very strong BT.
The New Madrid Earthquakes
Below are compared the 1811-1812 New Madrid Missouri quakes in the United States and The Berg Timer.
There were basicly four quakes referred to as the New Madrid quakes. The first two occurred on December 16 in northeast Arkansas. The third occurred on January 23 and was about the same strength as the first two. The fourth and final quake was the largest earthquake of the 1811-1812 series. As quoted from the USGS:
"Several destructive shocks occurred on February 7, the last of which equaled or surpassed the magnitude of any previous event. The town of New Madrid was destroyed. At St. Louis, many houses were damaged severely and their chimneys were thrown down. The meizoseismal area was characterized by general ground warping, ejections, fissuring, severe landslides, and caving of stream banks."
All quakes occurred at BT lows just prior to high BT days. The final and strongest of the four occurred just prior to the strongest BT day of the year, a "13" strength BT day.
The other quakes shown in March occurred in China (March 8), Venezuela (March 16), Rome (March 22), France (March 23), and four more occurred on March 26 in Caracas Venezuela.
The Strongest Earthquake in Chinese History
On August 22, 1902, the strongest quake in China's long history hit the Xinjiang area. It was reported 8.1 in strength by international seismographers. The Chinese government rates it at 7.8.
The quake occurred just two days before one of the strongest BT days in history, a "20" strength BT day on August 24.
One of the Deadliest Earthquakes in Recorded History
On July 27, 1976, a 7.8 quake hit Tangshan China, killing 240,000 people and causing $7 million damage. It occurred just before a very strong "14" strength BT day on August 10. It's listed by the source below as one of the most deadly quakes in recorded history.
The Strongest Earthquake in Alaska in 64 Years
On November 3, 2002 an 8.4 quake struck Fairbanks Alaska just three days after the strongest BT day of the year.
The Strongest Earthquake in Alaska History
On November 10, 1938 an 8.7 quake struck the Alaskan peninsula, just before the strongest BT period of the year (same data source as above).
Monthly Earthquakes 
Monthly earthquakes show the same correlation to The Berg Timer as daily quakes---high quake probability just before and after strong BT. Below are compared monthly U.S. earthquakes and monthly Berg Timer from 1971 through 1980. This chart was first published in the February 1991 Whole Earth Forecaster.
The brown columns are the number of quakes each month >5.0. The blue columns are the number of quakes >7.0. Green columns are quakes >9.0. I exaggerated the green columns x 5 so they would be easy to see; the green columns each represent one 9.0 earthquake. Quakes usually occur during low BT periods just before and after strong BT periods.
Data Source: Earthquakes of the United States. Hardbound book.
The chart below are quakes >5.0 from 1970 through 1996 compared to monthly Berg Timer using a different quake data source.
Quakes occur in clusters just before and just after strong BT periods.
Tsunamis
Most Tsunamis are caused by earthquakes so it's not surprising that Tsunamis correlate well with BT just like earthquakes.
Each Tsunami event is shown below for the active year of 1995 compared to daily BT.
Tsunamis are most likely just before and after strong BT.
The disastrous South Asia Tsunami of 26 December 2004 occurred just one day after a strong "9" strength BT day on December 25.
Moonquakes 
Between 1969 and 1972, six seismic stations were deployed on the lunar surface during Apollo missions. Seismic data was continuously recorded until 1977. Below are compared daily Moonquakes for 1976 and 1977 and The Berg Timer.
Just like earthquakes, moonquakes occur in clusters just before and just after strong BT days.
Note that most moonquakes occurred within two days of the strongest BT days of both 1976 and 1977.
Both earthquakes and moonquakes share the same timing behavior with respect to planetary positions, as represented by BT.
The conclusion:
The mechanism causing seismic activity is the same on two different celestial bodies. I submit that when seismic data is collected from all planets, it will be found that all planets share the same seismic correlation to The Berg Timer.
Whatever the mechanism, when the planets are in certain symmetrical and identical configurations (as represented by BT), seismic activity is caused on all planets immediately preceeding and following such configurations. The planets may act as armatures as they move through the solar system's interplanetary magnetic field, creating electromagnetic stress which affects all planets simultaneously within the field.
The name of this website should be changed to Whole Universe Forecaster.
Volcanoes 
Krakatau 
Below are compared the famous Krakatau Volcano eruption of August 26, 1883, and The Berg Timer.
Just like earthquakes, volcanoes occur just before and after strong BT days. Krakatau erupted just prior to the strongest BT day of the year, an unusually strong "14" strength day.
The eruption was preceeded by a column of ash and steam rising 11 km into sky from Perboewtan on May 20th and the top of Perboewtan being blown off in an eruption in mid-June (shown as smaller grey lines). 36,417 lives were lost (32,000 from the Tsunamis). The explosions were heard 4653 km away on the Island of Rodrigez in the Indian Ocean. A two meter high wave was recorded in Auckland, 7767 km away. The old island of Krakatau was destroyed. The former volcanic cones of Perboewatan and Danan fell into a hole in the crust which flooded with sea water. Only the southern part of Rakata remained. Two-thirds of the original island was destroyed.
Mount St. Helens 
Below are compared Mount St. Helens Volcanic Seismicity and the monthly Berg Timer.
From the first eruption, May 18, 1980, Mount St. Helens seismicity is most high just before and after strong BT. The monthly BT values for the two strong months in 1980 and 1982 are the highest BT values of the 20th century. A monthly BT of equal strength occurs again in July, 2020.
The strongest BT day of 1991 on June 9 (a '12 strength' day) coincided with the following volcanic activity as reported by the Omaha World-Herald:
"Manilla, Philippines (AP) - A volcano began spewing ash Saturday (June 8) for the first time in 600 years, and authorities planned an evacuation of nearby Clark Air Base if volcanic activity increased. Mount Pinatubo, a 4,795-foot volcano about 60 miles northwest of Manila, sent steam 16,000 feet into the air and sent ash as far as 15 miles away."
"Tokyo (AP) - Mount Unzen, a volcano that claimed at least 37 lives less than a week ago, burst to life again Saturday (June 8), spewing superhot debris that set homes on fire and blacking out a nearby city of 45,000."
Tornadoes 
Below are compared daily combined tornado totals (from Nebraska, Iowa, Illinois, Kansas, Missouri, Oklahoma, Texas and Arkansas) compared to the daily Berg Timer during the 1994 tornado season.
Tornadoes are most probable just before and just after strong BT (BT has been inverted in the above chart for easy viewing). When BT is low, hitting "0", tornadoes are most probable. This is the same correlation as for earthquakes, moonquakes and volcanoes.
The Worst Tornado Outbreak in U.S. History
The most widespread tornado outbreak in U.S. history occurred April 3-4, 1974. 330 people died and 5,484 were injured during the 148 twisters in thirteen states. Seven category F5 tornadoes occurred on April 3, including the deadly Xenia Ohio twister. Below are all tornado reports during that period compared to The Berg Timer.
Tornadoes occurred during low BT periods just before and after high BT. The big April 3-4 outbreak occurred exactly at the lowest 3-day BT period on April 3.
2002 Tornadoes
There were forty-four F3 strength tornadoes in the United States in 2002. These twisters caused 32 deaths, 550 injuries and $386 million in property damage. Again, tornadoes are most probable during low BT periods (peaks in the above chart) immediately before and after strong BT.

Hurricanes, Typhoons, Cyclones and Tropical Storms 
Berg Timer Forecast for Atlantic Cyclone Events
Below are compared all Atlantic cyclonic activity for 1944 through 2007 compared to the Berg Timer. Cyclones include all hurricanes, tropical storms and subtropical storms with winds < 90 mph. The Berg Timer is the total daily BT value each year for June through September.
Like precipitation, tornadoes, and earthquakes, Low BT = High Cyclones. The major peaks in the Cyclones correspond, within one year, to major lows in BT (1948, 1955, 1961, 1969, 1975, 1981, 1990, 1995, 2001, 2005).
Note the major low of BT in 1969 which corresponds with the major high in cyclone events (Hurricane Camille, wind speed >160 mph).
Note the major high of BT in 1986 which corresponds with the major low in cyclone events (no hurricanes > 90 mph).
2008 should be an above average hurricane season.
Hurricane Genesis - 1999 through 2004 Hurricane Seasons
The chart above represents when Atlantic cyclones during the 1999-2004 seasons hit their strongest wind speeds after a Berg Timer of "5" strength or more. In the red box, all but 3 hurricanes hit their maximum strength 2 to 8 days after a BT "5" day. If it's necessary to be in the Atlantic/Caribbean area during hurricane season, you should schedule your visit outside the 2-8 day window occurring after a BT "5" day.
The wind speed charts for each season are shown below. The only misses were Hurricane Lili in 2002 and Isabel in 2003 when no BT=5 occurred. However, multiple "4's" occurred just prior to maximum winds of both.
The 2-8 day window for maximum hurricane strength probability discussed above is shown below for each occurrance of BT = 5 using a horizontal red line. Hurricane wind strength peaks 2-8 days after the Berg Timer = 5 or stronger. To order BT for any one year period into the future or the past, please see the Products page.
2004 Hurricane Season
BT forecasted that the 2004 season would be strong, with the 2-8 day window active for most all of the season.
CHARLEY wind speed peaked 7 days after The Berg Timer = 11.
FRANCES peaked 5 days after BT = 9.
IVAN peaked 5 days after BT = 6.
JEANNE peaked 5 days after BT = 5.
2003 Hurricane Season
BT forecasted the 2003 season with great accuracy, forecasting both genesis and peak strength.
Hurricanes are generated when daily hits "5" strength or greater. Then they hit their peak strength 2-8 days later.
You shouldn't plan on being in the Caribbean inside of a week after a spike in daily BT of value "5" or stronger and especially not with a daily Berg Timer value of "7" or higher. These forecasts are good for all cyclone generating oceans, Atlantic, Pacific and Indian.
The Eastern Pacific Hurricane IGNACIO began one day after very strong BT "12" day. Hurricane JIMENA began precisely on an BT "7" day. Note that no new hurricanes formed in early to mid October when BT was very low. Then Patricia formed again after BT hit "6" strength on October 17.
Notice also that hurricane genesis begins at the same time in different oceans. On August 28 when BT hit "7", two hurricanes began within three days of each other, each in different oceans. And three cyclones began within two days of BT=5 on October 3 in two different oceans. Hurricane genesis shares the same cause, regardless of location. That cause is atmospheric change as represented with BT.
2002 Season
Below are all hurricanes (4) for the 2002 Atlantic season compared to the daily Berg Timer. The BT forecast for 2002 was published here several months before the 2002 season.
BT correctly forecasted the beginning of hurricanes GUSTAV, ISIDORE and KYLE. All three hurricanes began within two days of the two strongest BT days of the period, September 5 and 16. Hurricane LILI began within 3 days of the strongest BT day. There were no new hurricanes formed afterwards as BT calmed down. Note how LILI re-generated itself after four BT = 4's occurred on 9/28-29 and 10/1-2.
2001 Season
BT's 2-8 day probability window correctly forecasted all periods of the most intense wind speeds of 2001.
2000 Season
BT's 2-8 day probability window was very accurate in forecasting the strongest wind periods of 2000.
