| Discovery and Significance of Volcanic Earthquake Geoheritage of Laoheishan Scenic Area in Wudalianchi Global Geopark |
| Laoheishan and Huoshaoshan in Wudalianchi Global Geopark in China are the latest active volcanoes with detailed historical records that erupted in 1720–1721 AD (300 years ago). It is difficult to distinguish between rock deformation caused by lava flow and structural deformation caused by the shaking due to earthquakes on lava platforms, although volcanic earthquakes are closely related to volcanic eruptions. Extensive research has been performed on volcanic eruptions and earthquakes in Laoheishan and Huoshaoshan by using seismic network records and historical materials, but there is no discovery and report on tectonic deformation caused by volcanic earthquakes. During the 1:2000 large-scale surveys of geoheritage in the Laoheishan Scenic Area, more typical structural deformation relics, such as ground cracks, earthquake mole track, extrusion ridges, lava collapse, and landslide were newly discovered. These deformations should be volcanic earthquake geoheritage based on their distinction from the lava plastic deformation and the comparison with typical earthquake geoheritage in other regions. They prove that earthquakes have occurred during the eruption of the Laoheishan volcano 300 years ago. The discovery of volcanic earthquake geoheritage has filled the blank in the earthquake geoheritage of Wudalianchi Global Geopark, and the analysis of this genesis and time has an important reference value for further studies on the rules of seismic activity. Furthermore, it can be a reference for the field investigation and research on volcanic seismic geoheritage in other volcanic geoparks in China. |
