The first disaster causes a lot of fires in the forests. Also, it throws a lot of volcanic gases which causes air pollution, such as, ash fall, CO2, and methane. "Mud volcanoes are one of the significant natural sources of atmospheric methane"(Dimitrov, 2002). The volcanoes affect the lands and cause landslides. On the other hand, the second disaster affects the cities more than the forests.
A natural hazard that does not affect California but common in the Philippines are tropical storms. The most recent and one of the most dangerous was Typhoon Haiyan in November 2013. 5260 people were killed, and the number may rise due to illness breaking out in camps. The Philippines is very prone to typhoons as they develop in the Pacific Ocean and move westwards towards the islands. California has a very hot climate and so tropical storms are extremely rare in the state.
Ricardo Perez Historical Processes of Puerto Rico San Fermin Earthquake of 1918 The geological position of Puerto Rico raises a concern for earthquakes in the modern day. The island is located very close to the junction of the Caribbean and North American tectonic plates. A combination of seismic and volcanic activity created the Caribbean islands as we know them today. All of the Caribbean islands, with the exception of Barbados, were created from the fierce volcanic activity of the millions of years ago during the Antillean Revolution. Violent movements of the plates in the Post-Glacial era created the Puerto Rican Trench, nearly 24,000 feet deep, which is the deepest point in the Atlantic Ocean.
J. Subbiondo © 2004The CrustThe outer layer of the Earth is called the crust. It is made up of rock that floated to the surface when the Earth was formed. It is not a continuous layer, but is made up of large masses called tectonic plates.These plates drift slowly across the Earth's surface (tectonic means moving).The movement of these plates creates mountains and valleys.At weak points in the crust, it causes volcanic eruptions. And when plates bump into each other, earthquakes occur -- emitting shock waves or vibrations called seismic waves. The crust is the Earth's coldest layer.
The volcanoes can be dangerous as well. Mt. Etna in Sicily, Italy is considered one of the most active volcanoes on earth. While Japan has over 100 active volcanoes, some that are very dangerous. These volcanoes are caused by tectonic plates that make up part of the earths surface.
There can be deaths, also, but only 5% of tornado deaths are caused by Weak Tornadoes. The next type is Strong Tornado. Significant Tornadoes (F2), which travel from 113 to 157 miles per hour and Severe Tornadoes (F3), which travel from 158 to 206 miles per hour, are classified as Strong Tornadoes. Theyusually last for about more than 20 minutes and can cause extensive damages: roofs of well-constructed buildings can be ripped off, trains can be overturned, and even large old trees can be uprooted and snapped. Not only properties and nature are damaged, but also human.
How to predict an volcanic eruption Ground Deformation Ground deformation is the change in shape that happens before during or after a volcanic eruption. This happens because the sides of the volcano change shape because the magma in many ways to measure the change of shape of the volcano, like leveling, triangulation and more recently using continuous Global Positioning System (CGPS). It is also possible to use lakes as large tilt meters. Tilt meters measure the tiny degrees of tilt or slope on land. This is one of the oldest methods of knowing when ground deformation was caused because of rising lava.
(Some geologists argue that this portion of the Eurasian Plate is actually a fragment of the North American Plate called the Okhotsk microplate.) A part of the subduction zone measuring approximately 190 miles (300 km) long by 95 miles (150 km) wide lurched as much as 164 feet (50 metres) to the east-southeast and thrust upward about 33 feet (10 metres). (“Japan Earthquake and Tsunami of 2011, 1”) A series of extremely destructive tsunami waves followed the 9.0 earthquake along with the dozens of foreshocks and aftershocks that came with it. The city of Sendai, its surrounding area and airport were pounded by a wave
Initially, hurricanes are formed over warm water in the tropical oceans and develop best when far from the jet stream while tornadoes are formed over land and formed within storms that are often very close to the jet stream. Other than that, hurricanes can be up to several hundred miles wide while tornadoes are usually not more than a quarter of a mile. Besides that, hurricanes can last up to 3 weeks while tornadoes usually last not more than an hour. Likewise, the strength of the wind of hurricanes are usually 180 mph while the maximum strength of the wind of tornadoes can be up to 300 mph. Additionally, hurricanes occur in the Atlantic Ocean with an average of 10 tropical storms
The climate is very bipolar though due to varying elevations and winds across the island. The east side of the island has the heaviest amount of rain which equals to about 3.5 meters a year. Not only does this side receive a great amount of rain it is also affected substantially more by the cyclones that wreak havoc on the tropical island. Rain clouds expel so much moisture to the east of the highest grounds the highlands in the central part of the island are much drier and cooler. The downside to the central highlands though are multiple thunderstorms that cause incredible damage due to lighting strikes.
