CVGHM reported that during 1-29 February multiple pyroclastic flows from Semeru traveled 500 and 2,500 m into the Besuk Kembar and Besuk Kobokan rivers (on the S flank), respectively. During 1 February-30 April dense gray-to-white plumes rose 100-500 m above Jongring Seloko crater and drifted W and N. Incandescence was visible up to 50 m above the crater during 1 February-31 March. Seismicity decreased from March to April. Observations indicated that the lava dome grew in April. On 2 May CVGHM lowered the Alert Level to 2 (on a scale of 1-4) and reminded the public not to approach the crater within a 4-km radius. ...plus

Notre Tour Leader pour les expéditions Doni est juste revenu d'une visite au Semeru et rapporte que le 27 mars, lui et notre groupe ont observés des explosions fréquentes toutes les deux ou trois minutes, avec beaucoup de puissance suffisante pour éjecter des bombes rayonnantes et produire des petites avalanches ardentes vers le bas sur le flanc sud du volcan.

I was on a flight yesyerday from Jember to Surabaya with 2 friends and saw Mt Semeru explode at app. 09.37 on the 18 Oct 2008.
