Visited Bromo again in October, mainly to observe the yearly peak of the Orionid Meteor Shower. However not many large and long-living meteors was observed.
This was my 5th visit this year. Activity in bromo has increased in 2015, compared to 2014. Gas emissions, especially sulphur outputs have increased in 2015. A constant rumbling sound could be heard during my visit to the crater on the 19th October, caused by what seems to be, intense gas pressure.
