Cosmos-1809 satellite data on ELF emissions, plasma density, Ne and variations dNe in the ionosphere above the Caucasus-Central Asia region during a period of enhanced seismic activity are presented. The data show that small-scale plasma irregularities with dNe/Ne ~ 3-8% and with a characteristic scale of 4-10 km along the orbit are excited on geomagnetic field tubes connected to the epicentral region, simultaneously with earthquake related ELF emissions. The empirical models of such emissions are developed on the basis of available experimental data.
