Volcano in Ecuador erupting

From: SelbyHort at aol.com on 1999.10.07 at 01:06:35(3706) The following posting was obtained from the NOAA site that monitors volcanic activity worldwide. Apparently the Guagua Pichincha Volcano that overlooks Quito has erupted with a thick cloud of ash. For those who might know them, Dr. Tom Croat, Dr. Dick Mansell, Lynn Hannon and Tom's assistant Beth, are all now in this area of Ecuador. I imagine that their trip to Lita will be eventful and memorable. At any rate, the eruption does not sound like a huge exposion such as Mt. St. Helens, but the ash falling over the area is sure to add some excitement to their travels. -Donna Atwood Selby Gardens +More ************************************** FVXX20 KWBC 052225.VOLCANIC ASH ADVISORY STATEMENT ISSUED 2225 UTC 05 OCTOBER 1999 BY THE WASHINGTON VAAC .
