The steam has melted a pond about 100 feet wide, the waters roiling with bubbles of hot volcanic gases rising from the magma.
The soils consist of finely broken up basaltic rock fragments and are highly enriched in sulphur and chlorine, probably derived from volcanic gas emissions.
The venting probably was produced by a combination of rain water percolating down to hot rocks and volcanic gas coming from deeper levels, scientists said.
Johnston was the first geologist on the volcano, and soon became a leader within the USGS team, taking charge of monitoring of volcanic gas emissions.
Another missing sign of a coming eruption is the absence, so far, of volcanic gases such as excess carbon dioxide, hydrogen sulfide or dinitrogen oxide.

However, water vapor is consistently the commonest volcanic gas; as a rule, it comprises more than 60 % of total emissions during a subaerial eruption.
We clearly show that in the Guatemalan subduction zone up to 95 percent of the nitrogen in volcanic gases comes from . . . marine sediments,
Volcanic gas emissions from this volcano are measured by a Multi-Component Gas Analyzer System, which detects pre-eruptive degassing of rising magmas, improving prediction of volcanic activity.
The snow-capped mountain _ 45 miles southeast of the sprawling capital city _ belched hot rocks and breathed scorching volcanic gas down its 17, 992-foot slope.
Thousands of trees at Mammoth Mountain southeast of Yosemite National Park were killed by an invisible volcanic gas, not by drought as originally thought, researchers say.
