Geological Summary

Lava flows from two isolated cinder cones NW of Lassen Peak blocked drainages, forming three small lakes. The cones lie SW of Burney Mountain and WNW of MaGee Peak. Lava flows from the Silver Lake cinder cone formed Silver Lake NE of the cone and crescent-shaped Author Lake to the east and traveled 3.5 km to the SW. The crater of Silver Lake cone is open to the SW. The flat-topped Buckhorn Lake cinder cone to the SE of Silver Lake dammed up Buckhorn Lake, NE of the cone, and produced a lava flow that traveled 3.5 km to the SW. These basaltic cones are of possible Holocene age, but lie outside the area of glaciation at Lassen and their age is not known with certainty.

The Global Volcanism Program is not aware of any Holocene eruptions from Silver Lake. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Silver Lake page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The small grayish area at the center of this NASA Landsat image is a lava flow from the Silver Lake cinder cone. Lava flows from the cone dammed up drainages, forming two small black-colored lakes, Silver Lake and Arthur Lake. Another small dark-colored lake at the lower right, south of the two large elongated light-colored areas, was formed when lava flows from the Buckhorn Lake cinder cone blocked a stream valley.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
