Geological Summary

Gunung Tanggamus is of Quaternary age (van Bemmelen 1949b). Its products, which mostly consist of lavas, breccias, and tuffs of predominantly dacitic and andesitic composition, dominate the geology of the western part of the Lampung Province in southern Sumatra (Zulkarnain, 2011). Older Tanggamus products close to the main cone are generally pyroclastic breccias, consisting of porphyritic andesite and lapilli tuff. The younger products that make up the relatively undissected cone are of intermediate composition, and those deposits in the proximal zone surrounding the cone and in more distal regions are pyroclastic and laharic breccias and ignimbrites (Husein et al., 2015). The ignimbrites appear to be younger than the pyroclastic breccias (Husein et al., 2015). The lavas on Tanggamus are vesicular and porphyritic, and at about 1.4 million years old, are younger than the pyroclastic breccias and ignimbrites. The laharic breccias, consisting of porphyritic andesite and pumice, yielded an age of 1.5 Ma; however, field observations indicate that these units may be younger (Husein et al., 2015).

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Tanggamus. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Tanggamus page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

WOVOdat
   Single Volcano View
   Temporal Evolution of Unrest
   Side by Side Volcanoes

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments.

IRIS seismic stations/networks

Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Tanggamus. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice.
