A plume rises above the summit crater of Yasur, seen here from the west across Lake Siwi in 1988. Yasur has produced near-continuous Strombolian activity since at least 1774 and this style of activity may have continued for the past 800 years. The mostly-unvegetated cone is has a 400-m-wide summit crater.
