Volcanoes are closely linked to the movement of tectonic plates, the massive slabs of rock that make up Earth’s crust. Most volcanic activity occurs along plate boundaries. 1. Subduction Zones When one plate slides beneath another, it melts into magma.…
The Richter scale is a logarithmic scale used to measure the magnitude of earthquakes. Developed in 1935 by Charles F. Richter, it quantifies the energy released at the earthquake’s source. How the Scale Works Each whole number increase represents 10…
Solar storms are powerful bursts of energy released from the Sun, often caused by solar flares or coronal mass ejections (CMEs). When these charged particles reach Earth, they interact with the magnetosphere, the protective magnetic field surrounding our planet. What…
A second powerful earthquake has struck the state of Yaracuy, Venezuela, this time registering a magnitude 7.5 at a shallow depth of 10 km on 24th June 2026. Shallow earthquakes of this size are capable of producing intense ground shaking across…
A powerful magnitude 7.1 earthquake struck the state of Yaracuy, Venezuela on 24th June 2026 at a shallow depth of 10 km. Shallow earthquakes of this size are capable of producing strong, widespread shaking, and early reports indicate that tremors were…
A powerful magnitude 7.8 earthquake struck eastern Mindanao at a shallow depth of 45 km, making it one of the strongest seismic events to affect the Philippines in recent years. Shallow mega-thrust earthquakes of this size are capable of causing…
A magnitude 5.9 earthquake struck the Molucca Sea at a shallow depth of 40 km, producing noticeable shaking across nearby islands in eastern Indonesia. No major damage has been reported, but this region is known for frequent moderate to strong…
It is regarded as the southern section of the East Pacific Rise in some usages, generally south of the Challenger fracture zone which is associated with a triple junction between the Juan Fernández microplate, the Pacific plate and the Antarctic…
The province borders the provinces of Jambi to the north, Bengkulu to the west and Lampung to the south, as well a maritime border with the Bangka Belitung Islands to the east. It is the largest province in the island of Sumatra, and it is slightly smaller than Portugal, the…
Frederick Hasselborough, an Australian, discovered the uninhabited island on 11 July 1810, while looking for new sealing grounds. He claimed Macquarie Island for Britain and annexed it to the colony of New South Wales in 1810. The island was named for Colonel Lachlan Macquarie, Governor of New South Wales from 1810 to…
