ANOTHER AUGUST 7M EARTHQUAKE!

...at a Glance (with time ticking)

(Source data can change without notice or correction.)



Earthquakes of 5.0 to 5.9M thru Wednesday--12; two quakes of 6M or greater: 8/21 7.2M SOUTH ISLAND OF NEW ZEALAND, 8/14 6.3M GREECE (last reported earlier)

California earthquakes in past week--267; none of 4M or greater

Volcanic ash over 5 mi (8 km)--none

Sunspot No. high--113 on 17 August

Smallest to largest daily total area of sunspots--230 on 20 August from 660 on 14 August

(100 equals a Planet Earth area.)

X-Class Solar Flares: none detected; last M-Class flares (5/day) 8 on 11 June (see ticker for fewer MC, if any)

Planetary Geomagnetic Indices: high of 86 on 18 August;

one set of K-Indices of 4 or more (5 or more/24 hours*)--17-19,21 August

(* The 24 hour period can overlap two days.)



Moon for August per Astronomy Magazine

5 first quarter, 6 perigee, 12 full, 19 last quarter, 19 apogee, 27 new, 31 another perigee

The moon is at another perigee (228,618 miles near) on 31 August.






August Mars Calendar:

30 July to 29 September--Retrograde motion of Mars in the Constellation Aquarius

27 August--Closest to Earth (34.6 millions miles near), New Moon

28 August--Opposition (alignment of Sun, Earth, Mars)

30 August--Perihelion (128.4 million miles nearest the Sun)



Mars arises in the east in the evening after sunset. It is the brightest object in the sky after the Sun and the Moon.



ISRAEL Earthquakes do occur, and the most recent 25 quakes are shown on a map at http://www.gii.co.il/html/seis/seis_fs.html .

Most are north or south of Israel on the line of the Jordan River valley.



AURORA SURPRISE: "On Aug. 18th, Northern Lights appeared as far south as California and Arizona in the United States. The display was a surprise. It was triggered by the interplanetary magnetic field (IMF), which unexpectedly tilted south after a knotty magnetic structure in the solar wind drifted past our planet. South-pointing IMFs promote strong geomagnetic activity." (from www.spaceweather.com )



Recent Volcanic Eruptions:





DUKONO Halmahera, Indonesia 1.70°N, 127.87°E; summit elev. 1,185 m

volcanic activity at low levels during 8-15 August, sulfur-dioxide emissions generally high, with maximum emission rates on 11-12 August





Ash data is summarized from the weekly GVN/USGS report at

http://www.volcano.si.edu/reports/usgs/

SPECIAL NOTE



Atmosphere Effects from Aerosols in Volcanic Eruptions



From the Smithsonian's Global Volcanism Network:


quote:




In April and May of 1982 El Chichon volcano in Mexico erupted with such a volume of gases that the atmosphere of the planet was changed for years. Here is a URL for a graphic illustration (Fig. 26) of the atmospheric effect of some volcanoes and atmospheric aerosols:

This is the list on Atmospheric Effects from the Smithsonian:

This is the explanation:
