Mauna Loa For approximately 28 million years, the Hawaiian hotspot has belched out islands and atolls. The hotspot sits in the same position, spewing upward from the mantle, while the Pacific Plate moves above it. This combination created the string we know as the Hawaiian Islands. Eight major isles comprise the archipelago. Each was once …
The Valley of Ten Thousand Smokes “The sight that flashed into view…was one of the most amazing visions ever beheld by mortal eye. The whole valley as far as the eye could reach was full of hundreds, no thousands–literally tens of thousands–of smokes curling up from its fissured floor…It was as though all the steam …
Mount Edgecumbe Just over 100 miles south of Alaska’s Glacier Bay National Park resides a stratovolcano known to the Tlingit as L’ux. The name means “to flash” or “blinking,” a fascinating moniker for a volcano, ostensibly because the Tlingit first encountered the mountain while it produced smoke or erupted. In an interesting etymological confluence, lux is …

The Decade Volcanoes On 22 December 1989, the United Nations General Assembly designated the oncoming decade – the 1990s – as the International Decade for Natural Disaster Reduction. The gist was to reduce the loss of life and property due to tsunamis, earthquakes, floods, storms, droughts, landslides, and volcanoes. The resolution intended to identify and study some …
The Loudest Sound On 27 August 1883, reverberations from the northwest disturbed the morning serenity of sheep ranchers outside Alice Springs, Australia. The men later described the sound as “a series of loud reports, resembling those of artillery.” No war raged in central Australia in 1883; no military exercises took place. Were these ranchers under attack …
Frankenstein’s Monster Volcano Mary Shelley might not be the first name encountered when considering women in science and nature, but she led an extraordinary life and has an intriguing connection to one of the largest events in geologic history. Additionally, many literary critics dubbed one of her novels as the first science-fiction piece ever written. Her …
Mauna Kea – Hawaii’s High Point Hawaii is the youngest full-fledged addition to the United States of America and perhaps the least congruent. It is, after all, a string of islands in the middle of the Pacific Ocean. The state isn’t the only one with volcanoes, but it is unique in that it was created …
Documenting Demise As we explored in the previous issue, Mt. St. Helens began to display activity in March 1980, a string of action that led to the largest recorded landslide and an incomprehensible lateral blast on May 18. This two-month period allowed geologists and amateur scientists time to study the mountain in the buildup. Many volcanologists …
The Mt. St. Helens Eruption Today is the 40th anniversary of the eruption of Mt. St. Helens. Located in southern Washington’s Skamania County, the stratovolcano is 50 miles northeast of Portland and 100 miles south of Seattle. In early 1980 the mountain was 9,677 feet high, making it the fifth-highest peak in the state. Rising …
