Authorities say another three people are missing in a landslide just north of Quito.
Three people were killed in two separate slides. The man whose today death in the hospital was announced by the interior minister was struck by loosened earth while working on bridge-building project.
The fourth person killed in yesterday's quake was a child crushed by bags of falling rice in Quito.
Damage was not widespread but slides blocked several highways and more than 30 aftershocks were felt.
