The National Earthquake Monitoring & Research Centre maintains and operates a nationwide seismological network. The seismological records are integrated into an acquisition-treatment workflow that allows detecting and locating local and teleseismic earthquakes. A database comprising all the seismic events is documented as and when the seismic signals are analysed at each seismic centre (NEMRC
, and RSC).
The seismic bulletins produced by the analysts are shared with the International Seismological Centre (ISC) on regular basis since the early years of the network (in the 1980s), and contribute therefore to the reviewed ISC bulletin. The bulletin shared with ISC comprises all local earthquakes greater than ML 4 ( ~ Mw 3) and teleseismic earthquakes recorded at NEMRC.
Seismic catalogues are exported from the seismic databases on regular basis for DMG internal needs. In addition, catalogues are concatenated and qualified before the publication of DMG seismicity maps.
Some extracts of the seismicity catalogues have also been published and are shared as repository data material of articles, provided that the articles from which they belong are properly referred.

Kakani is one of the historical stations of the DMG-DASE collaboration. A first station was deployed there on March the 27th
1980. In the aftermath of the Gorkha earthquake, a broadband station was installed, complementing the historical short period z component ZM500 station. The broadband seismic signals at that station were telemetered since then.
The seismic records are shared hereafter. The station is registered as KKN under the FDSN network NK.

Continuous GNSS time series were acquired at 3 stations in the framework of the DASE-DMG collaboration since November 1997. The permanent GNSS monuments were installed on a transect of the Himalayan range at the longitude of Kathmandu. These historical stations (Gumba - GUMB, Daman-DAMA and Simra-now SIM4) were complemented later by more than 20 stations deployed by Caltech (PI. JP Avouac) within the framework of the Nepal Geodetic GPS Network (NGGN). In the meantime, the 3 historical DASE-DMG stations were maintained and upgraded on regular basis to insure the homogeneity of the NGGN network.
The last major upgrade date back from the aftermath of the Gorkha-2015 earthquake. The three Trimble NetR9 stations are now integrated in the seismic network telemetry to Kathmandu.
The cGPS data are distributed here in RINEX3 format, on regular basis, since their update
