How strong is an earthquake?
Events with magnitudes greater than 4.5 are strong enough to be recorded by a seismograph anywhere in the world, so long as its sensors are not located in the earthquake’s shadow. The following describes the typical effects of earthquakes of various magnitudes near the epicenter. The values are typical only.

What is the most deadly tsunami in history?
On March 3, 1933, the Sanriku coast of northeastern Honshu, Japan, which suffered a devastating tsunami in 1896 (see above), was again stuck by tsunami waves resulting from an offshore magnitude 8.1 earthquake. The quake destroyed ~5,000 homes and killed 3,068 people, the vast majority as a result of tsunami waves.
What are the 5 natural disasters?
A natural disaster is a major adverse event resulting from natural processes of the Earth; examples are floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, and other geologic processes.

Why do earthquakes often occur in the Philippines?
The Philippines lies along the Pacific Ring of Fire, which causes the country to have frequent seismic and volcanic activity. Many earthquakes of smaller magnitude occur very regularly due to the meeting of major tectonic plates in the region.
Where is Pacific Ring of Fire?
Pacific Ocean

Why is there lava inside the Earth?
It erupts non-explosively and moves very quickly when it reaches Earth’s surface as lava. This lava cools into basalt, a rock that is heavy and dark in color due to its higher iron and magnesium levels. Basalt is one of the most common rocks in Earth’s crust as well as the volcanic islands created by hot spots.
Why might volcanoes be found in lines or groups?
Earth’s volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle. Therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging, and most are found underwater.
Why are there volcanoes in Hawaii?
The local tectonic plate (in the case of the Hawaii hotspot, the Pacific Plate) slowly slides over the hotspot, carrying its volcanoes with it without affecting the plume. Over hundreds of thousands of years, the magma supply for the volcano is slowly cut off, eventually going extinct.
