Geological Summary

The Qal'eh Hasan Ali volcanic field in SE Iran contains 14 maars of late Quaternary age, which were erupted through desert alluvium, granodioritic rocks, and Eocene volcanics in an area several hundred kilometers away from the closest Quaternary volcanoes. The maars, which produced tephritic pyroclastic deposits, have diameters ranging from 150 to 1200 m. The largest, known as Great Crater, is 1.2 km wide and 200-300 m deep. Ar-Ar dating of phlogopite in volcanic bomb samples from Great Crater gave ages of 112-119 ka (Pang and others, 2015).

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Qal'eh Hasan Ali. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Qal'eh Hasan Ali 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.

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 Qal'eh Hasan Ali. 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.
