SUNSPOT WATCH: Sunspot 431 is growing fast. During the last 24 hours it has swollen four-fold in area, and now poses a threat for X-class solar flares. Follow it at www.spaceweather.com .



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)

Mars rises in the east in the late evening after 1 August, advancing to early evening by 31 August. It is the brightest object in the sky after the Sun and the Moon.

MORE Volcanos acting up



The following references came from Ruthanne Lidmann, Dave Thomson and the Volcano List:



The Sunday Aug. 10 Internet edition of the Denver Post carried a lengthy article on the monster bulge at Yellowstone Lake, labeling it a "hydrothermal event".



http://www.denverpost.com/Stories/0,1413,36~53~1561852,00.html



=================================

In New Zealand at White Island water has created the largest crater lake

known there, submerging all the volcanic vents.



http://www.gns.cri.nz/what/earthact/volcanoes/bulletins/wizv070803.html



For those interested in going and seeing, remember that volcanic gases can kill people.

=================================



Soufriere Hills volcano on Monsterrat, West Indies, continues in an eruptive state, and reports frequently estimate the gas emission. The report also documents what is done to safeguard the remaining population:



Montserrat Volcano Observatory, Montserrat, W.I.

Report for the period midday 1 August to midday, 8 August 2003



..At the close of last week's report, the volcano was extremely active with intense ash venting from the explosion crater. Throughout most of the rest of the week, the volcano was fairly quiet with occasional rockfalls. ..



Sulphur dioxide emission rates were high for most of the week, ranging from 700-900 tonnes per day on 1-5 August. On 6 August the emission rate dropped slightly to 450 tonnes per day.



Residents of Montserrat and visitors to the island are advised to tune into ZJB Radio for up-to-date information on the volcano. Access to all areas south of the summit of Garibaldi Hill and the Belham Bridge gate, and to Bramble airport and beyond is prohibited. There is a maritime exclusion zone around the southern part of the island that extends two nautical miles beyond the coastline from Trant's Bay in the east to Isles Bay on the west coast.

++++++++

The deepest ocean trench in the Atlantic is the Puerto Rico Trench, north of Puerto Rico. In the past couple of month there has been continuing seismic activity in an arc west, north and east of Puerto Rico. Montserrat is a ways south and east of Puerto Rico. Montserrat's volcano, Soufriere Hills.



There is a seamount (underwater volcano) in the Juan de Fuca plate off the Oregon coast.



Mentioned last week is the volcano near the recent 7.6M Carlsberg ocean ridge quake on July 15th
