You can use CreateDynamicSphere. (You'll need Incognito's streamer plugin.)

new explosionarea;

public OnGameModeInit() {
    explosionarea = CreateDynamicSphere(explosion x, explosion y, explosion z, 10.0);
    return 1;
}

public OnPlayerEnterDynamicArea(playerid, areaid) {
    if(areaid == explosionarea) {
        // things & stuff
        CreateExplosion(explosion x, explosion y, explosion z, type, radius);
    }
    return 1;
}
