Deformation during 2007 - 2011 [uplift; Observed by InSAR]

Deformation during 1993 - 2005 [uplift; Observed by InSAR]

Start Date: 1993 Stop Date: 2005 Direction: uplift Method: InSAR
Magnitude: Unknown Spatial Extent: Unknown Latitude: Unknown Longitude: Unknown

Remarks: PS-InSAR shows slight uplift of the Tatun volcano group during the observation period, 1993-2005.

Slant range displacement rate of the processed PSs in the northern Taiwan area. This result has been adjusted by using the base point of ?Taiwan Vertical Datum 2001? installed by the Ministry of the Interior in Keelung harbor as the control point. Topographic map in background is the Taiwan digital elevation model from Taiwan Forestry Bureau. Shortening in slant range (rate in negative with warm colors) represents land uplift and elongation (rate in positive with cold colors) represents land subsidence in slant range direction. Black solid lines mark the main active faults and dashed lines are the inactive faults defined by the Central Geological Survey: (1) Chinshan Fault; (2) Shanchiao Fault; (3) Kanchiao Fault; (4) Taipei Fault; (5) Hsinchuang Fault; and (6) Nankang Fault. Black triangular: leveling survey points after Hou (2007). White dashed lines encircled the PS pixels that will compare with leveling data along profiles A and B in Fig. 11. Black dashed line frame XX? defines the PS pixels that will show in Fig. 12.

Photo Gallery


The Tatun (Datun) volcano group forms the northernmost part of Taiwan, north of the capital city of Taipei (lower left). About 20 andesitic lava domes are included in the Tatun group. The two small narrow peninsulas west of the top center of this NASA Landsat image mosaic (with north to the top) are formed by lava flows from the Tatun group. The latest eruptions in the group are of late Pleistocene and mid-Holocene age, but hot springs, fumaroles, and solfataras are found over wide areas, and extensive geothermal exploration has occurred.

The latest eruptions in the group are of late Pleistocene and mid-Holocene age. Hot springs, fumaroles, and solfataras are found over wide areas, and extensive geothermal exploration has occurred.

A phreatic eruption from a fissure on the west side of Cisingshan lava dome, seen from the west, took place at the time of the Cisingshan debris avalanche about 6000 years ago. The fissures contain small funnel-shaped craters that were the sources of explosive breccias several hundred meters wide and several meters thick that were considered to possibly be related to lithostatic unloading of the youngest lava flows of Cisingshan, which may have occurred only a few years before the collapse.
