While working as Controller in Charge I had a sector quicklooked behind the desk as it was the busiest sector. Another sector controller had a question to which I told him to standby as I noticed an MSAW alert on the quicklooked scope. By the time I noticed there was an aircraft below the MIA(Minimum IFR Altitude); there was nothing I could say to the Controller working the aircraft as the aircraft was climbing. I do not think the controller working the sector ever issued a lower altitude alert. I think the controller did not understand that we are required to avoid MIAs while the aircraft is climbing to the MEA(Minimum Enroute Altitude).
ZSE Controller in Charge reported observing a sector with an aircraft below the Minimum IFR Altitude.
