Five　M　s　7.0　earthquakes　(Wenchuan,　Yushu,　Lushan,　Jiuzhaigou　and　Maudo)　have　occurred　on　the　eastern　Tibetan　Plateau　since　2008,　and　＞　20　historical　earthquakes　(M　s　＞=　5.0)　have　also　been　recorded,　demonstrating　the　strong　seismic　activity　prevalent　in　this　region.　Owing　to　the　geomorphology　of　the　region,　consisting　of　alpine　valleys　with　a　lack　of　Quaternary　deposits,　it　is　difficult　to　conduct　paleo-earthquake　research　through　the　excavation　of　trenches.　Lacustrine　sediments　are　regarded　as　the　most　suitable　archives　for　paleo-earthquake　studies　because　they　often　comprise　a　detailed,　long-term,　and　continuous　environmental　record.　To　assess　the　seismic　activity　of　the　Diexi,　we　studied　a　well-exposed　outcrop　of　Xinmocun　lacustrine　sediments　that　included　three　sections　(XMCI　(11.5　m),　XMCII　(5.6　m),　and　XMCIII　(11　m))　near　Diexi　Lake,　moving　from　a　lake　shore　to　lake　center　environment,　at　the　intersection　between　the　Minjiang　fault　and　Songpinggou　fault.　Taking　into　account　the　geodynamic　setting　of　the　area　and　its　known　tectonic　activity,　soft-sediment　deformation　structures,　including　load　and　flame　structures,　injection　structures,　ball　structures,　pseudo-nodules,　boudinage　structures,　plunged　sediment　mixture,　liquefied　breccia　and　micro-faults,　discovered　within　the　sections　are　interpreted　as　seismites.　High-resolution　grain-size　and　magnetic　susceptibility　indicators　were　used　to　obtain　a　continuous　record　of　the　changes　in　physical　properties　within　the　three　sections　enabling　the　recognition　of　additional　seismic　events　that　did　not　result　in　soft-sediment　deformation　structures.　Rapidly　deposited　layers　with　underlying　soft-sediment　deformation　structures　in　the　sections　record　five　(XMCI,　XMCII　and　XMCIII)　seismic　events;　these　comprise　siliciclastic-enriched　sandy　sediment　fluxes　from　earthquake-triggered　landslides　or　dust　of　siliciclastic-enriched　clastic　materials.　Isolated　rapidly　deposited　layers　(without　underlying　soft-sediment　deformation　structures)　record　18　(XMCII),　12　(XMCI),　and　21　(XMCIII)　additional　earthquake-induced　inputs　of　detrital　material　into　the　lake.　Optically　stimulated　luminescence　and　14　C　dating　of　the　XMCI,　XMCII,　and　XMCIII　sections　indicate　continuous　sediment　deposition　from　19.4-9.9　ka,　15.5-10.1　ka,　and　18.7-10.6　ka,　respectively,　and　the　seismic　events　recorded　in　these　sections　can　be　cross-correlated　within　the　age　error　range.　Hence,　there　are　a　total　of　30　seismic　events　recorded　within　the　Xinmocun　sediments　during　the　period　18.6-10　ka,　suggests　a　weakly　periodic　pattern　with　an　apparent　recurrence　time　of　similar　to　280　years.　The　Minjiang　fault　and　Songpinggou　fault　are　Holocene　active　faults　with　a　risk　of　causing　strong　earthquakes.　Due　to　the　Diexi　area　is　located　at　the　intersection　of　the　Minjiang　fault　and　Songpinggou　fault,　and　has　frequent　seismic　activity,　suggest　a　high　seismic　risk　in　the　future.
