TephraDB_Prototype_ver1.2

This is the updated tephra fall distribution map dataset for assessing tephra fall hazards (thickness in mm) in Japan. This database was created using the database of Suto et al. (2007) (https://www.jstage.jst.go.jp/article/bullgsj/58/9-10/58_261/_article/-char/ja/) with ArcGIS.

This version is a revised version of ver1.1. Some errors were found in Hokkai_Koma_Ko_h, Hokkai_Koma_1998, NGO, Fuji_SWR, S_16_3, and ACP4 in ver1.1. Please use this version instead of ver1.1.

The exact method is available in Uesawa et al. (2022) appliedvolc.biomedcentral.com/articles/10.1186/s13617-022-00126-x. Please find the scripts to create the hazard curve at https://github.com/s-uesawa/Prototype-TephraDB-Japan.

Special thanks to Dr. K. Komura @CRIEPI for this revision.

Caution! Some more errors were found in this version. Please use ver1.3.
