It may just be coincidence but I am inclined to believe that the sun does influence geo-magnetic activity on earth.

Solar activity markedly increased this week, with the sunspot number rising to 130 on Monday, August 1 — the highest since a reading of 131 on April 14, 2011. The average daily sunspot numbers more than doubled this week compared to last, rising nearly 54 points to 99.3. ……
NOAA’s Space Weather Prediction Center: “Three coronal mass ejections (CMEs) are currently en route to Earth, with the commencement of geomagnetic storming expected early to mid-day on August 5 with the arrival of the CMEs associated with the August 2-3 events. The third of the string, seemingly the fastest CME, may catch up with the first two in the next 12-18 hours, compressing the plasma and enhancing the embedded magnetic field. Storming levels are expected to attain G3 (strong) conditions. The current Solar Radiation Storm may experience a kick with the shocks and attain S2 (moderate) thresholds.
“Some level of geomagnetic disturbance is expected to continue through August 7 as the series of CMEs affect the Earth. Continued activity is likely from these regions as they continue to rotate off the visible solar disk over the next seven days. The Space Weather Prediction Center will continue to monitor this event as it unfolds.”

Eighteen Indonesian volcanoes are on “alert” status, two of which are at Alert Level 3, which is called “Siaga”, the Volcanology and Geology Disaster Mitigation Center says. Center head Surono said Sunday in Jakarta the erupting Mount Lokon in North Sulawesi and Mount Ibu in North Maluku were the two volcanoes at Siaga status. The center has adopted four levels of alert status: “Normal” (Level 1), “Waspada” (Level 2), “Siaga” (Level 3) and “Awas” (Level 4).
Surono said the conditions at Mt Lokon and Mt Ibu were currently considered most worrisome because they had been consistently erupting searing clouds affecting a radius of 2.5 kilometers. ……
Surono added that 16 other volcanoes were at Level 2 alert status, “Waspada”, including Mt. Papandayan and Mt. Guntur in West Java. “Locals have reported several quakes,” he said. ….
Surono said that President Susilo Bambang Yudhoyono had summoned him on Saturday to report the volcanoes’ status and the center’s preparations to anticipate possible disasters.
