Dear RG researchers
Is there any record of earthquake that triggered more than 50,000 landslides?
Thanks for positive feedback.
Regards
Ijaz
Obviously the Wenchuan earthquake, but have a look at Schmitt's database to find others.

Please look at the table 1 of this article. At least four earthquakes triggered more than 56, 000 to 197,481 landslides and one triggered 50,000 landslides.

I am not sure the total number of landslides is really that meaningful. If you map thousands of earthquake triggered landslides you will focus on the big ones and will not pay attention to small ones. So if the official record documents 30,000 landslides there might be 30,000 additional small ones that no one cared to map.
It really depends on the mapping approach.

Landslides occurred mostly along weakly cemented and indurated rocks, colluvial sand and cemented soils. It is also worth noting that fissures and ground crack which were induced by main and after shock are still present and they pose a major potential threat for future landslides in case of another earthquake activity or under extreme weather conditions.
On 12 November 2017 at 18:18 UTC (21:48 Iran Standard Time, 21:18 Arabia Standard Time), an earthquake with a moment magnitude of 7.3 occurred on the Iran–Iraq border, with the Iraqi Kurdish city of Halabja, and the Sunni Kurdish dominated places of Ezgeleh, Salas-e Babajani County, Kermanshah Province in Iran, closest to the epicentre, 30 kilometres (19 mi) south of the city of Halabja, Iraqi Kurdistan.
It was felt as far away as Israel and the United Arab Emirates. With at least 630 people killed (mostly in Iraq's Kurdish Halabja area and the Iranian Kurdish dominated province of Kermanshah), and more than 8,100 injured, as well as many more unaccounted for, it was the deadliest earthquake of 2017.
The M=7.3 12th November Iran-Iraq earthquake is now known to have killed over 450 people. As the story slowly drops from the news, some information is emerging about landslides triggered by the earthquake. Unfortunately there is still considerable confusion, and interestingly at times it seems that the landslides are being interpreted as the fault rupture. Once again I am reminded that the understanding of landslides in the earthquake community is not as strong as would be ideal.
The largest set of landslides appears to have occurred close to the village of Mela Kabod in Iran, at about 34.535, 45.898.
There is extensive slip in the upper portion of the slope as well. These appear to be lateral spreading type landslides with quite limited slip (though the resolution of the images is 3 metres, so those tension cracks must be quite large)

can you help me with the acceleration records of halabja earthquake I couldn't find it and I need it desperately.
