This forecast had many good points despite very moderate solar driving conditions (common at this time of year).
Quakes barely made it to Mag 6 but the biggest quakes fitted the forecast profile well.
The Southern Sumatra 6.4 was a risk location from the 5-9 August forecast but was dropped from this forecast, a frustrating mistake.
Volcanoes picked up late in the period, including Piton de la Fournaise.
Volcanic action usually follows quake action so eruptions typically come late or soon after a quake period.
Heavy rain in Sierra Leone caused a hillside to collapse with many people buried.
The West Asia Monsoon has delivered a very heavy dose of rain to the Himalayan Foothills, leaving many villages underwater and millions of people displaced.
Christchurch got some very heavy rain.
Canterbury skifield operators watched with glee as half a meter of powder snow fell on top of earlier snowfalls making this the best ski season for a long time.
Standard meteorologists realise the global warming story doesn't fit so the catchcry is changing from "climate warming" to "climate change."
Little Ice Age weather fluctuations are being hijacked into the global warming political agenda but it is a square peg bashed awkwardly into a round hole.
